What Is Strategic Spatial Planning Environmental Sciences Essay

IntroductionStrategic spacial planning is arguably an attack which rails against the discourse of the scientific rational comprehensive theoretical accounts of be aftering which has and still does keep a big influence in current manners of planning. This short essay will hopefully explicate to contrivers why a strategic spacial planning attack is more contributing in the current context which we find ourselves in. This will be done through replying a set of inquiries which will clear up the attack, its intent and methods, how it differs from rational comprehensive attacks of maestro planning and land usage planning, why contrivers should utilize it, what can be expected from it, and its utility.What is Strategic Spatial Planning?Strategic spacial planning is a method to assist work out complex spatial jobs through making strategic visions and new spacial individualities. Harmonizing to Kaufman and Jacobs ( in Albrechts, 2001 ) strategic systems originated in the US around the 1950 â €˜s due to the demand for quickly altering and turning corporations to be after efficaciously and pull off their hereafters at a clip when the hereafter seemed ill-defined. In Europe, strategic spacial planning dated back to the 1920s and 30s, and was used to direct the activities of others ( Mastop in Albrechts, 2001 ) . From Albrechts ( 2006 ) it can be understood that the word ‘spatial ‘ brings into focal point the ‘where ‘ of things, the creative activity and direction of particular ‘places ‘ and sites every bit good as the interrelatednesss between different activities in an country, and important intersections and nodes within an country. This spacial focal point allows for a more effectual manner of incorporating different dockets – such as, economic, societal, and cultural – and their spacial impacts ( Albrechts, 2006 ) . The word ‘strategy ‘ has its roots within a military context ; in ancient conflict ground forcess would work out a scheme prior to the conflict on how best to get the better of the enemy. It is understood that this type of scheme had four basic elements – an accurate apprehension of the existent state of affairs, realistic ends, focused resources in countries where they would be most effectual, and continuity of the action until the coveted result is achieved ( Albrechts, 2010 ) . These elements are strongly rooted in systems of strategic spacial planning. In its entireness, strategic spacial planning is a procedure which is directed at a limited figure of strategic cardinal issue countries. It determines an countries strengths and failings in the context of its chances and menaces ; it scans external tendencies, and the resources that are available. It gathers major public and private stakeholders and allows for a wide and diverse procedure of engagement. It develops a realistic long-run vision along with schemes in order to pull off and act upon spacial alteration. Importantly it is orientated towards determinations, actions, consequences, and execution, in the short, average and long-run ( Albrechts, 2001 ) . â€Å" It is so impossible to understand material topographic points and societal nodes such as ‘the metropolis ‘ , ‘the city-region ‘ and ‘the part ‘ in footings of a unidimensional hierarchy of graduated tables † ( Albrechts, 2010:6 ) . This definition illustrates that strategic spacial planning is non a individual construct or process, but it is a set of constructs, processs and tools that are tailored carefully to whatever state of affairs is presented ( Albrecht, 2001 ) . Furthermore it is a development-led attack and a transformative and integrative, public sector-led, and socio-spatial procedure through which a vision, consistent actions and agencies for execution are produced ; these are so able to determine and border what a topographic point is and its potency of what it may go ( Albrechts, 2006 )How does it differ from MASTER PLANNING and LAND USE PLANNING?In order to understand the difference one needs to understand the principle of land usage planning and maestro planning. Land usage planning is a procedure of be aftering which is concerned with the location, strength, signifier, sum, and harmonisation of land development required for a assortment of spacial utilizations ; such as lodging, industry, diversion, conveyance, instruction, and agribusiness. A land usage program in this case fundamentally embodies a proposal as to how land should be used within a set of considered policy as enlargement and restructuring advancement in the hereafter ( Albrechts, 2004 ) . Traditional land usage planning is a more inactive planning attack aimed at commanding land usage through a zoning system and through ordinances. This harmonizing to Albrechts ( 2006 ) seems unfit for bridging the spread between plan-making, political decision-making and execution. This was one of the grounds why the demand arose for a different type of be aftering – a move off from regulative policy and instruments to a development-led attack which aims to step in more straight, coherently and selectively in societal world and development – strategic spacial planning ( Albrechts, 2006 ) . For Albrechts ( 2001 ) strategic spacial planning is to a certain extent rendered towards an integrated socio-economic class of action that supersedes the mere focal point on land usage planning. For Master Planning on the other manus, Friedman ( 2007 ) found that it is about a universally recognized signifier of planning pattern. His study found that in state after state, metropoliss through their authoritiess are mandated to bring forth maestro programs. Basically within these maestro programs states specify future land utilizations and location determinations. Maestro planning is a wholly inactive pattern and harmonizing to Friedman ( 2007 ) it needs to be rethought as it is out of line with the dynamic flows of globalization. Friedman ( 2007 ) defines master be aftering as being typically municipal programs instead than regional programs, and as being entirely concerned with land usage instead than with the entire spectrum of urban policy issues. They are drawn up by a specialised subdivision of municipal authorities instead than through a wider procedure of collaborative deliberation, and the procedure used to pull up maestro programs and acquiring them approved takes old ages therefore rendering them out-dated by the clip they can be implemented. Besides they are top-down, with comparatively minimal citizen engagement, and in conclusion when it comes to big scale undertakings ; maestro programs are frequently set aside to let for necessary alterations in land usage and circulation forms ( Friedman, 2007 ) . Opposing this, spacial planning is derived non from an functionary, compulsory character like maestro planning but from a function that coordinates instruments closely intertwined with urban policy formation and the design and execution of large-scale undertakings. Spatial be aftering involves a scope of histrions that include communities, authorities functionaries and private stakeholders. The chief intent of spacial planning is non to mandate peculiar land uses – as is in the case of maestro be aftering – but to let for a better coordination of urban policies and large-scale undertaking developments across infinite, to prove alternate policies and designs through revising their societal deductions, and to let for an informed public discourse about them ( Friedman, 2007 ) . In metropoliss such as the new downtown peninsula of Vancouver, maestro planning has been abandoned for systems of spacial planning in which be aftering returns by manner of affecting public hearings, bargaining, and dialogues. The consequences of this passage over a period of 25 old ages are testimony to the viability non merely of the Vancouver theoretical account but besides of the more abstract spacial planning theoretical account ( Friedman, 2007 ) .What are its chief PURPOSES and METHODS?Strategic spacial planning as mentioned earlier is used for complex jobs where governments at different degrees and different sectors and private histrions are reciprocally dependent ( Albrecht, 2001 ) . The theoretical account designs plan-making constructions and develops content, images and determination models which can act upon and pull off spacial alteration. It is about building new thoughts and processes that can transport these constructions through, therefore bring forthing ways of ap prehension, ways of consensus, and ways of organizing and mobilising for the intent of exercising influence in different spheres ( Albrecht, 2006 ) . Both is the short and long term, strategic spacial planning focal points on bordering determinations, actions, undertakings, consequences and execution, and incorporates monitoring, feedback, accommodation and alteration of the result. Its intent therefore is non a new political orientation prophesying a new universe order but as a method for making and maneuvering a better hereafter for a topographic point based on shared values ( Albrechts, 2006 ) . Albrechts ( 2006 ) goes farther on to explicate that the seven chief purposes of a strategic undertaking are – to develop an incorporate advanced attack for the assorted undertaking types ; to develop a to the full operational model based on sustainability ; to develop tools for quality direction ; to broaden the multi-actor/multi-level policy scenes and to measure current scenes ; to circulate the attack ; to develop an educational theoretical account ; and to set up a web of cognition between research workers, professionals, and authoritiess ( Albrechts, 2006 ) . The capacity for these undertakings to present the coveted result is dependent foremost on the system itself and on the conditions underlying it – such as structural restraints, and political, cultural, and professional attitudes towards spacial planning. The planning procedure is non intended to flux swimmingly from one stage to the following. It is a dynamic and originative procedure wherein new positions and facts that arise today may change the determinations made yesterday ( Albrechts, 2010 ) . This illustrates that it is ne'er a fixed procedure but is in a uninterrupted start of alteration from get downing to stop. The visions and frames which guide this procedure are ne'er ‘a given ‘ , instead they are to be constructed. The procedure of picturing is the procedure by which groups develop visions of future provinces for themselves, their administrations, metropolis, or their part that are clear, powerful and realistic. Basically this means that the visions are to be constructed within a specific context and scale sing issues that are of involvement within that infinite and within a peculiar combination of histrions. This is to be done within a method that to the full recognises the conditions of power, inequality, and diverseness. â€Å" The vision describes a metropolis or part as it may look like in the hereafter, and it must appeal to the long-run involvements of histrions who have a interest in the metropolis or part † ( Albrechts, 2010:8 ) .Why do this sort of planning?Strategic spacial planning undertakings conduct an in-depth survey of the country, therefore giving pen chant to the location being affected over anything else. With this these undertakings study external tendencies and the resources available hence leting for a wide and diverse procedure. Besides, by doing usage of this type of planning, contrivers are able to aim a assortment of countries ; including urban, rural, and economic countries ( Albrechts, 2006 ) . In the case of urban countries, strategic urban undertakings are utile as they aim to consolidate, transform, restructure or recycle the urban countries for new and emerging demands from public and private histrions. With respects to rural countries, strategic undertakings are utile as they aim to transform rural and suburban kineticss into a more sustainable and qualitative signifier of development while non burying to heighten the cultural significance of these infinites. Last, economic countries are seen as an of import portion of the attempt to maintain up international economic fight. Strategic undertakings seek to turn away from the old construct of concern Parkss spacial construct and direction to a focal point on the demands of houses that are to be translated into specifically designed employment locations ( Albrechts, 2006 ) .And what can we anticipate from it?This inquiry can be divided into two parts ; ‘we ‘ as contrivers and ‘we ‘ as the populace and private histrions. First, the essay will mean to the reference the latter portion. Strategic spacial planning undertakings are strategic to accomplish visions, ends, and aims from a assortment of policy sectors, and are to incorporate the community being affected. Visions is arguably one of the most of import factors of strategic undertakings as they are expected to be placed within the specific context, topographic point, clip and degree, and are to see specific issues that are of involvement to the different histrions ( Albrechts, 2006 ) . Basically what can be expected from strategic spacial planning undertakings is a critical analysis of the chief procedures and structural restraints which form infinites, which adds into a realistic, dynamic, integrated, and declarative long-run vision. It will supply a program for short-run and long-run actions, a budget, and a flexible scheme for execution ( Albrechts, 2010 ) . In footings of the undertakings eventual execution, it will supply believable committednesss to action battle and a clear and expressed nexus to the budget therefore leting for citizens, private-sector, different degrees of administration, and contrivers to come in a consensus ( Albrechts, 2010 ) . ‘We ‘ as contrivers will anticipate a different set of tools, tools which will steer the contriver on what to anticipate when moving as a strategic spacial contriver. For Albrechts ( 2010 ) , he finds it unthinkable that the contriver should move simply as a impersonal perceiver and chorus from playing a function in the building of visions and images. Alternatively, Albrechts suggests that contrivers should be needfully involved, and instrumental in confirming, explicating and implementing images and visions. This is a logical position, as if contrivers simply observe, there expertness in certain state of affairss are non shared, and their utility would be greatly undermined. Strategic spacial contrivers are to alternatively, challenge their ain ‘mental discourse ‘ which limit their creativeness, and get down afresh therefore leting for their creativeness and resourcefulness to flux and to be used in formulating, designing, and constructing new constructs and discourses ( Albrechts, 2010 ) .How utile is it?Strategic spacial planning is a flexible procedure that trades with complex jobs and is able to repair to a broad scope of jobs, but besides trades with each job unambiguously. This characteristic makes the attack really utile as it applies to a scope of different issues. For illustration ; the metropolis of Barcelona started utilizing a strategic planning attack in 1988 in order to heighten the cooperation between the public and private sector with the hope that the sweeten ing will beef up the place of the metropolis as a campaigner for the Olympic Games ( Albrechts, 2010 ) . The metropolis of Turin which was inspired by Barcelona besides undertook a strategic attack in the mid 1990 ‘s, for Turin this formed the footing for rethinking the potency of a former monopolistic town that had been extremely affected by the rise of the car industry. The purpose for Strategic spacial planning here was to transform Turin into a European city – â€Å" a metropolis of activities and know-how † ( Albrechts, 2010:5 ) . For the metropolis of Bilbao, the vision was to transport the metropolis into the economic, fiscal, and cultural capital of the Atlantic Arc. Last, for Prague, strategic spacial planning focused on incorporating the metropolis into European constructions ( Albrechts, 2010 ) . From this it is clear that strategic spacial planning is applicable to a diverse scope of issues and can accommodate easy to what is required in the context for which it is visualizing, therefore rendering it a utile attack to planning.DecisionFrom the information discussed in this essay the attack of strategic spacial planning has been explained. Through utilizing such an attack to be aftering it can be deduced that infinites can be become more active and synergistic both on a local graduated table – and the sectors within that scale – and on an international graduated table. â€Å" In short, episodes of strategic spacial planning informed by â€Å" relational complexness † constructs which accumulate sufficient power to â€Å" go † efficaciously and have digesting stuff and mental effects should be judged in the long-run in footings of their capacity to enrich the inventive resources, originative energies and administration civilizations through which quality of life and experience of diverse citizens and stakeholders in peculiar topographic points are likely to be enhanced. † ( Healey, 2006:19 )

Case Study Bharat Airways

Case Study Bharat Airways Evaluating the case and the plan of action for Bharat Airways The main problem facing Bharat Airways is the poor relationship between employees and management. In fact, the firm is deficient of human resources management competencies. Managing employees is one of the critical factors that contribute to the organizations success.Advertising We will write a custom case study sample on Case Study: Bharat Airways specifically for you for only $16.05 $11/page Learn More Poor leadership styles are the other problems facing the firm. In fact, the firm has chosen autocratic leadership style that has resulted into deprived relationship between employees and the top management. The result is reduced performance among employees, which eventually have negative effect on the performance of the firm. Bharat Airways should come up with various strategies that would address the employees concerns and the leadership styles. The first strategy is to change leadership and the management styles. The Company should adopt leadership and management approaches that motivate and encourage employees towards attainment of the organizations goals (Bass Riggio, 2008). In addition, the leadership and management styles should encourage communication between the employees and senior management and remove vices such as discrimination that tend to discourage employees’ work performances. Moreover, the leadership style should focus on creating positive change among employees through encouraging creativity and innovativeness in solving the problems facing the organization. The other plan for the organization should focus on creating positive relationship with the customers. Focusing on positive relationship with the customers entails generating services with additional value that satisfy clients beyond their expectations. Ensuring that the services provided are beyond the customers’ expectations will increase the firm’s clients’ base (Bangs, 2002). Focusing on customers will also ensure increased sales and revenue, which is critical for the growth and development of the firm. Research methodology In order to investigate the root causes of the problems faced by Bharat Airways, the study will utterly be a quantitative research. The requisite research data will be gathered across the study population through random sampling strategy.Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More A research technique dubbed as survey method will essentially be drawn on while descriptive statistics will be applied to help analyze the obtained data. By employing these research methods, any unanticipated research hypothesis will possibly be suggested, formulated and the study will be quicker and somewhat cheap. Besides, while investigating root causes of the problems, descriptive quantitative study method is considered suitable for th is particular research. Thus, the researcher intends to conduct the research study using Bharat Airways employees, customers, and the firm’s key informants whereby data will be gathered using a sample size of 200 hundred respondents. In fact, appropriate study sample will be chosen through organized random collection process. Research questions including the number of trained and untrained workforce, employees’ satisfaction, the rate of turnover, communication channels, leadership styles and customer contentment level will be asked. The researcher will administer a well-designed and tested study questionnaire to the respondents during survey to generate first hand research data. For the survey execution and design to be both effective and resourceful, the researcher will use follow-up mailings, response incentives, and offer pre-notification protocol advice to the study respondents. The implementation and administration of the research instruments following these strat egies will influence the general realization of satisfactory responses and successful generation of research data. Research Instrument Developing the research questionnaire is one of the key aspects of the study methodology given that the instrument is intended to serve its intended purposes. The instrument will follow the nine steps iterative guideline or framework proposed that will improve the content validity. The survey instrument also known as research questionnaire will be espoused and drawn on in this particular study both for conceptual and practical reasons. Thus, in this research, the root causes of the problems will be measured using organizational values as well as the employees, customers and management opinions.Advertising We will write a custom case study sample on Case Study: Bharat Airways specifically for you for only $16.05 $11/page Learn More Due to time and cost constraints, random sampling will be used to select the required responden ts. Although random sampling is quick and convenient method for selecting the participants, the researcher is free to select the participants who are accessible and convenient though not necessarily representative. Every respondent will be informed about voluntary participation and the level of confidentiality given to the information provided. In fact, the researcher will request the participants not to indicate their names and other personal or confidential information on the questionnaires to increase the chances of participation. Besides, the level of participation will be handled by informing the participants about the significance of the study. All these measures will assist in reducing non-response rates. Data analysis Given the nature of the research study to be conducted, descriptive statistics will be used to analyze data. In addition, data will be edited to ensure logical completeness and response consistency. Besides, the collected research information will be analyzed q ualitatively and quantitatively. The qualitative data will be analyzed using logical analysis and content analysis techniques. Regression analysis will be conducted to determine the relationship between the factors being investigated. The transactional and transformational style of leadership and the best leadership style for Bharat Airways Transactional leadership Transactional leadership focuses on the interactions between the top management and employees. In fact, in transactional leadership styles, rewards and punishments are used as a form of motivation. Rewards are in various forms and are provided to employees with increased performances and loyalty. Transactional leadership styles are effective in situations where increased performance is the major objective of the organization (Bass Riggio, 2008). In addition, transactional leadership works better in the circumstances where the problems can clearly be observed and simple. In other words, employees understand the limit and the consequences of their actions.Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More One of the major disadvantages of the form of leadership is that employees are aligned to the organizations requirements. In other words, transactional leadership does not encourage innovativeness and creativity in solving the organizational issues (Bass Riggio, 2008). In other words, the leadership style does not allow employees to be creative and innovative in getting solutions to the problems. Employees do not contribute creatively and innovatively in getting solutions affecting their work processes. The leadership style is not suitable in complex organizations where creativity and innovativeness remains critical in the attainment of goals and objectives. Most importantly, under complex situations where employees’ contribution is emphasized, transactional leadership is not the best approach (Bass Riggio, 2008). Essentially, Bharat Airways cannon apply transactional leadership style in managing employees given the complexity of the organization and the current situation. Transformational leadership Transformational leadership is characterized by its inspirational nature and positive changes it creates in an organization. Transformational leadership takes into consideration the concerns of employees and is focused on encouraging employees to achieve the goals of the organization. In fact, transformational leadership is geared towards creating positive change among employees. Moreover, in transformational leadership style, the members of the team are encouraged to attain the desired results on the assigned tasks. Further, leaders impart the vision of the group and take into consideration the members’ contribution in the attainment of the results. Besides, Transformational leaders have greater vision as well as inspirational characteristics, which is applied to motivate and change the expectations as well as perceptions of employees to work towards the desired goals and outcome. Given the circumstances in Bharat Airways, transformational leaders hip style is the best employees’ management approach. The reason is that employees of Bharat Airways need to be encouraged, motivated and inspired towards attaining the goals of the organization. In addition, Bharat Airways need visionary leaders to inspire and motivate employees towards attaining the desired outcome. Such characteristics are found in the transformational leadership style. The immediate steps to improve the situation of the organization The first step is to create a vision for the organization and formulate clear objectives that are achievable and measurable. Once the vision, mission and objectives have been formulated, a clear strategy outlining the steps on how the organization’s goals will be attained is then established. The vision, goals, and strategies are communicated to the employees as well as other stakeholders of the organization. Imparting the vision, goals and strategies will ensure that all stakeholders are involved in the attainment of t he organization’s goals. The second step is to come up with strategies that will ensure a change in the management of employees and leadership styles. The new management style will remove obstacles that alienate employees from work processes. The leadership style should encourage employees towards attaining the desired outcome. Implementing 7P’s marketing mix Product strategies The firm designs and produces varieties of airline products and services. The services include in-flight and on ground services. However, the innovative capabilities of the firm will be fully utilized to ensure the development and production of quality products and services that offer varied airways choices for customers (Constantinides, 2006). Moreover, the firm will aspire to introduce creative airline services and products in the airways market to establish its brand name. The products and services will be improved to suit the customer needs and bring convenience, a mixture of value and quali ty. Pricing strategies As expected, quality and increased value will attract high prices (Constantinides, 2006). Most of the Bharat Airways services are middle-high priced. However, the firm offer services that target all clients including high-end, middle and low classed travelling customers. The high-quality high-prices strategy will be applied particularly to outperform other airline competitors. In addition, the pricing strategy will be aimed at widening the spectrum of customers being targeted. In fact, the firm has been targeting customers at all levels. As such as, commissions or discounted prices will be offered to clients who use airlines often. Nevertheless, with entry of more competitors in the airline industry, Bharat Airways will widen its scope and capture the middle, high, and low-income clientele. Bharat Airways will also offer different prices to the clients including apex fares, low cost, cheap value, premium and value for money. Placing strategies Bharat Airways w ill adopt the business to customer distribution channel in order to directly deal with its customers. Direct interaction with customers will lead to the development of products and services that suit the customers’ needs. Moreover, direct sales of products and services will lead to prolonged market share. However, the routes of the airline around the world are still limited given that the firm is centrally placed. Therefore, Bharat Airways will expand its operation routes to reach all sorts of customers. The placement strategies will include offering affiliated services with different companies, using travelling or tour operator agencies, as well as making the twenty-four hours online reservation systems available to all clients. The promotion strategies The promotion strategies to be used by Bharat Airways will include advertising, public relations and sales promotions. The firm will use innovative advertising to attract and inform customers about products and services offer ed both in mass and digital media. Besides, Bharat Airways will associate its products and service with sports companies to increase brand name awareness and maintain public relations. The success of Bharat Airways in public relations will improve its goodwill and attract public attention. Further, Bharat Airways will provide special offers to associated sports people as a way of stimulating and retaining the customers’ loyalty. People Mix strategies Bharat Airways will employ a pool of competent and reliable workforce to deliver airline services to the customers. During recruitment, qualities such as responsiveness, compassionate attitude and problem cracking capabilities will be assessed. Besides, all employees must depict goodwill and inventiveness before being hired in the firm. Process mix strategy Given that Bharat Airways aims to deliver quality airline services to the clients, the organization will offer flight entertainment, repast services, luggage management servic es, airport facilities, flight statistics and reservation services. Physical evidence Bharat Airways will provide both in-flight and ground services to the clients. The in-flight services will include having tags or markers, luggage, ambiance, uniform, sanitation, decent inner surfaces, seats alignments and branded airplanes. On the ground, physical evidence will include branded tickets, logos, paperwork, ticket or booking offices.

Emily Dickinson - Continuing Enigma

Emily Dickinson - Continuing Enigma Known for:  inventive poetry, mostly published after her deathOccupation:  poetDates:  December 10, 1830 - May 15, 1886Also known as:  Emily Elizabeth Dickinson, E.D Emily Dickinson, whose odd and inventive poems helped to initiate modern poetry, is a continuing enigma.   Only ten of her poems were published in her lifetime. We know of her work only because her sister and two of her long-time friends brought them to public attention. Most of the poems we have were written in just six years, between 1858 and 1864. She bound them into small volumes she called fascicles, and forty of these were found in her room at her death. She also shared poems with friends in letters. From the few drafts of letters that were not destroyed, at her instruction, when she died, its apparent that she worked on each letter as a piece of artwork in itself, often picking phrases that shed used years before. Sometimes she changed little, sometimes she changed a lot. Its hard to even tell for sure what a poem by Dickinson really is, because she changed and edited and reworked so many, writing them differently to different correspondents. Emily Dickinson Biography Emily Dickinson was born in Amherst, Massachusetts. Her father and mother were both what we would today call distant. Her brother, Austin, was bossy but ineffective; her sister, Lavinia, never married, and lived with Emily and was protective of the much shyer Emily. Emily at School While signs of her introspective and introverted nature were apparent early, she traveled from home to attend Mount Holyoke Female Seminary, an institution of higher education founded by Mary Lyons. Lyons was a pioneer in womens education, and envisioned Mount Holyoke as training young women for active roles in life. She saw that many women could be trained as missionary teachers, especially to bring the Christian message to American Indians. A religious crisis seems to have been behind young Emilys decision to leave Mount Holyoke after a year, as she found herself unable to fully accept the religious orientation of those at the school. But beyond religious differences, Emily also apparently found the social life at Mount Holyoke difficult. Withdrawn Into Writing Emily Dickinson returned home to Amherst. She traveled a few times after that once, notably, to Washington, DC, with her father during a term he served in the U.S. Congress. But gradually, she withdrew into her writing and her home, and became reclusive. She began to wear dresses exclusively in white. In her later years, she did not leave her homes property, living in her home and garden. Her writing did include letters to many friends, and while she became more eccentric about visitors and correspondence as she aged, she had many visitors: women like Helen Hunt Jackson, a popular writer of the time, among them. She shared letters with friends and family, even those who lived nearby and could visit easily. Emily Dickinsons Relationships From the evidence, Emily Dickinson fell in love with several men over time, though apparently never even considered marriage. Her close friend, Susan Huntington, later married Emilys brother Austin, and Susan and Austin Dickinson moved to a home next door. Emily and Susan exchanged ardent and passionate letters over many years; scholars are divided today on the nature of the relationship. (Some say that the passionate language between women was simply an acceptable norm between friends in the nineteenth and early twentieth centuries; others find evidence that the Emily/Susan friendship was a lesbian relationship. I find the evidence ambiguous at best.) Mabel Loomis Todd, a descendent of John and Priscilla Alden of Plymouth colony, moved to Amherst in 1881 when her astronomer husband, David Peck Todd, was appointed to the faculty of Amherst College. Mabel was twenty-five at the time. Both the Todds became friends of Austin and Susan in fact, Austin and Mabel had an affair. Through Susan and Austin, Mabel met Lavinia and Emily. Met Emily is not exactly the right description: they never met face-to-face. Mabel Todd read and was impressed by some of Emilys poems, read to her by Susan. Later, Mabel and Emily exchanged some letters, and Emily occasionally invited Mabel to play music for her while Emily observed out of sight. When Emily died in 1886, Lavinia invited Todd to attempt to edit and publish the poems Lavinia had discovered in manuscript form. A Young Contributor and Her Friend The story of Emily Dickinsons poems, with their interesting relationship to womens history, is highlighted by the most fertile period of Emily Dickinsons writing, the early 1860s. A key character in this story is better known in American history for his support of abolition, woman suffrage, and transcendentalist religion: Thomas Wentworth Higginson. Hes also known in history as the commander of a regiment of black troops in the American Civil War; for this accomplishment he proudly used the title Colonel Higginson to the end of his life. He was the minister at the wedding of Lucy Stone and Henry Blackwell, at which he read their statement renouncing any strictures that the law placed on the woman when she married, and stating why Stone would keep her last name rather than assuming Blackwells. Higginson was part of the American literary Renaissance known as the Transcendentalist movement. He was already an recognized writer when he published in 1862, in The Atlantic Monthly, a short notice titled Letter to a Young Contributor. In this notice, he solicited young men and women to submit their work, adding, every editor is always hungering and thirsting after novelties. Higginson told the story later (in The Atlantic Monthly, after her death), that on April 16, 1862, he picked up a letter at the post office. Opening it, he found a handwriting so peculiar that it seemed as if the writer might have taken her first lessons by studying the famous fossil bird-tracks in the museum of that college town. It began with these words: Are you too deeply occupied to say if my verse is alive? With that letter began a decades-long correspondence that ended only at her death. Higginson, in their long friendship (they seem only to have met in person once or twice, it was mostly by mail), urged her not to publish her poetry. Why? He doesnt say, at least not clearly. My own guess? He expected that her poems would be considered too odd by the general public to be accepted as she wrote them. And he also concluded that she would not be amenable to the changes that he thought necessary to make the poems acceptable. Fortunately for literary history, the story doesnt end there. Editing Emily After Emily Dickinson died, her sister, Lavinia, contacted two friends of Emilys when she discovered the forty fascicles in Emilys rooms: Mabel Loomis Todd and Thomas Wentworth Higginson. First Todd began to work on the editing; then Higginson joined her, persuaded by Lavinia. Together, they reworked the poems for publication. Over some years, they published three volumes of Emily Dickinsons poems. The extensive editing changes they made regularized Emilys odd spellings, word usage, and especially punctuation. Emily Dickinson was, for instance, very fond of dashes. Yet the Todd/Higginson volumes have included few of them. Todd was sole editor of the third volume of poems, but kept to the editing principles theyd worked out together. Higginson and Todd were likely correct in their judgment, that the public could not accept the poems as they were. The daughter of Austin and Susan Dickinson, Martha Dickinson Bianchi, published her own edition of Emily Dickinsons poems in 1914. It remained until the 1950s, when Thomas Johnson un-edited Dickinsons poetry, for the general public to experience her poems more as shed written them, and as her correspondents had received them. He compared versions in the fascicles, in her many remaining letters, and published his own edition of 1,775 poems.

Compare and contrast between liberalism and conservatism Essay

Compare and contrast between liberalism and conservatism - Essay Example High level of individual freedom is the core of classical liberalism whereas liberal conservatism advocates small governmental intervention on individual matters. In other words both are similar as far as individual freedom is concerned. Classical liberalism advocates private property and liberal conservatism also do not deny earning of private property. Liberty and prosperity were the major slogans of classical liberalism. Liberal conservatives also emphasize human's freedom, capitalism and a free economy/market. Progressive liberals are not much keen in doing what they advocate in their manifesto. Most of their principles and policies were lie on paper alone. On the other hand, traditional conservatives believe in natural laws and moral principles. Tradition, custom, hierarchy, patriotism, localism regionalism etc are different dimensions of traditional conservatism whereas progressive liberals will never advocate all those things publicly, but they engage in similar activities pri vately.

Training teachers to produce software program and using in their classes - Thesis Proposal Example Additional research has demonstrated that 53% of the aspiring teachers who participated believed that they had confidence in their software programming skills in the classroom (Yost et al. 2003). Studies have shown that 50% of all educational professionals apply software educational material in the learning environment. The application of computer aids differs from educational locations. In some locations, the instructor application of software programming approaches 100%. In other locations the instructor application of software programming is nil. Many instructors attribute this deficiency to time constraints, economic constraints and deficiency in instructor preparation (Education World n.d.). The instructor application of software has been proven to increase student’s ability in quantifiable courses. The instructor application of the software programming has yet to be proven to enhance the students’ skills in social studies, language and the arts. Research has demonstrated that software programming consists of various levels which may be assessed distinctively. These implementations may be applied with varying levels of success to quantitative and graphic courses (Roschelle et al. 2001). There are courses which provide effective lesson administration and enable aspiring teachers to aggregate interactive classroom participation in the lesson plan. Those desiring to become educators may acquire the software programming skills in order to properly administrate the lesson plans and connect items to an assortment of web based resources. The web based resources may apply visual and auditory aids in order to facilitate classroom instruction. Aspiring teachers may acquire or enhance software programming ability by the following implementations: The integration of software programs in the classroom by the aspiring teachers

The Importance Of Wastewater Treatment Environmental Sciences Essay

The Importance Of Wastewater Treatment Environmental Sciences Essay Water scarcity is the major problem that is faced all across the world. Although 2/3rd of the earths crust is made up of water but all this water is not available for drinking and for other human activities as either it is locked in the form of ice or present in the form of vast saline oceans and seas. It has been found out that 97% of the total water is salty that is of no use to human and animals (except marine animal) and the remaining three percent is available as freshwater. More than half of this three percent is locked in glacier and less than 0.01% is available as fresh water. So water resources are less as compare to human demand for water. Above this, the major part of water that can be consumed is getting polluted because of human activities. This polluted and untreated water is causing abundant water borne diseases. Then the world is facing a huge climatic change which is further aggravating the water problem. Some of the regions are getting more rain water than earlier and some are getting almost negligible. Experts even believe that the next World War would not be for oil or land but it will be for water. Also because of improper use of water and lack of water treatment, the problem of water crisis will further increase where 884 million people are already not getting easy access to safe drinking water. And a further 2.5 billion people are getting difficult access to water for disposable and sanitation. Agriculture is also overusing and polluting the ground water thus depleting the natural source of water. So here water treatment plants will play important role. Water crisis at present is the biggest problem according to the United Nations. Almost 25 countries of Africa, parts of China, Peru and Brazil in Latin America, some parts of Middle East like Iran, Chile, Mexico, and Paraguay are some of the countries that are facing the water crisis. Even other parts of the world are facing the varied levels of the water crisis. Because of acute shortage of water, the food problems are getting aggravated. About 40 million people in Africa are facing the problem of food shortage. It is expected that if the similar conditions will persist then there will be 500 million till 2025 who will suffer from these problems. Nature has its role but the major water problem is arising because of its increasing consumption and faulty usage. Major chunk of the problem can be solved if the wastewater treatment is taken very seriously and precautions at every step are taken to improve the water quality. The supply and demand The demand for fresh clean water delivered to our homes is ever increasing as more and more residential homes are being established. Although 70% of the world is covered with water, only 1% is fresh water and thus raises a need to recycle waste water to satisfy our needs. Efforts to continuously recycle waste water are always stressed upon as a shortage would mean a disaster in heavily populated areas. Governments have committed billions towards research and development to such projects. Fresh water is also needed in agriculture. The demand for water in this sector is very high as farmer need fresh water for crops and cattle. Therefore, stresses the demand for sewage water treatment plants to be built. Water from rivers and lake are inadequate to provide water for farm and residences alike. The supply of sewage water treatment facilities are slowly dwindling. A crisis may arise from a lack of sewage water treatment plants as this would greatly reduce the supply of fresh water. Governments are desperately trying to keep up with the pace of development of the population but are slowly lagging behind. The supply of fresh water will be adequate for the next few years but if the development of sewage water treatment plant continues at its current pace it without a doubt a shortage would take place. Furthermore, the agriculture industry will be greatly impacted and the supply of food will go down as well leading to famine due to a shortage of water. The prospects of this industry The wastewater treatment industry most probably will be successful in future due to presence of new wastewater treatment technologies. Advanced Immobilized Cell Reactor technology is one of the new technologies which immobilize the organisms such as bacteria in the pores of the carbon matrix. This process can avoid the immobilized organisms from shock load application as the diffusion of the pollutants from bulk fluid phase to organisms follows Ficks law. Through conventional biological wastewater treatment, infinite electrical energy and vast land area are being consumed. Besides that, a huge investment in electromechanical equipment is involved which will bring about a huge total cost of operation. Generally, the total cost of operation for new technology is lowered compared to the convention technology. By using the new technology, the total cost of operation can be cut down to approximately 50 percent of the total cost of conventional treatment. Furthermore, the biological oxygen demand and chemical oxygen demand are reduced by 94 percent and 90 percent respectively. Oxygen consumption in the new technology is lower than in conventional technology. The oxygen gas is supplied in the form if compressed air from the bottom of the reactor. Both liquid and gas streams are in counter-current direction which facilitates the oxidation of dissolved organics and desorbs the converted products. This is to make sure the activated carbon keep up its activity throughout the process. Moreover, with all those new wastewater technologies such as Advanced Oxidation Process, NERV (Natural Endogenous Respiration Vessel), Wet oxidation and many others processes, wastewater treatment can be done efficiently. For instant, through the new technologies less land is required to use to build plant; the power consumption is lowered. Besides that, the requirement for electrical and mechanical equipment is lower compared to conventional technology. In a conclusion, wastewater treatment industries have a good prospect in the future with the help of new technologies. By using all those new technologies, waste water treatment can be done efficiently with lower overall lifecycle costs, lesser energy and equipment needed. We are sure that there is more new technologies will be invented in order to improve the wastewater treatment. The impact on the environment When the waste water is mixed with the waste materials such like garbage, household waste, toilets liquid and disposable things, the resulting product called sewage or waste water. This sewage water is normally will undergo a few process before it is release to the environment but there are still some impact on the environment. One of the impacts on the environment is agricultural impacts. The sewage water contains salts which is soluble that may accumulate in the root zone with possible harmful effect on soil health and crop yield. The physical and mechanical properties of the soil, such as dispersion of particle, stability of aggregates, soil structure and permeability are very sensitive to the types of exchangeable ions present in irrigation water. Thus, when effluent use is being planned, several factors related to the soil properties must be taken into consideration. On the other hand the effect of dissolved solids in the irrigation water on the growth of plants is also another aspect of agriculture which we have to concern. Dissolved salts increase the osmotic potential of soil water and increase the osmotic pressure of the soil solution which increases the growth and the yield of most plants decline progressively as osmotic pressure increases. In addition the one of the environment impact is ecological impact where the drainage water from waste water irrigation schemes drains particularly into small confined lakes and water bodies and surface water, and if phosphatesin the ortho phosphate form are present, the remains of nutrients may cause eutrophication. Here the overloading organic materials resulting in decrease in dissolved oxygen may lead to changes in the composition of a aquatic life such as fish deaths and reduced fishery. The eutrophication potential of waste water irrigation can be assessed using biological indices, which in turn can be qualified in monitory units using economic valuation techniques. The hidden impact on the environment is the increase on the production of green house emissions. The large agriculture reuse project might cause to the environmental externalities associated with pumping water uphill which emits greenhouse gas. Another impact is on the health. The sewage water contains pathogenic microorganisms like bacteria, viruses, protozoans and parasitic worms, the diseases and signs related with such infection are also diverse including typhoid,dysentry and cholera, diarrhea and vomiting. the concentration of he pathogens in waste water is dependent on the source population and the susceptibility to infection varies from one population to another. So basically he waste water is actually harm for the nature even though its treated and release to the environment so as a human being we should not dispose the waste into the water thus our water will be clean and the cost of the treatment can be reduced. The Processes involved in this industry Pre-Treatment(prepared by Brian Lee CL, 0902669) Pre-treatment consists of three sub-stages which are Screening, Grit Removal and Fat and Grease Removal. Pre-treatment is done to remove materials which are easily collected such as debris, leaves and trash which would damage or clog up pumps and skimmers of the primary treatment. Screening is used to remove large objects such as leaves, twigs and cans in the sewage stream. This is normally done with a giant mechanical rake bar which is automated. The rake bar revolves around a central axis at a rate varying on the accumulation and flow rate of the sewage stream. The screens vary in sizes to optimize solid removal. Objects accumulated are collected and disposed in landfills. Grit is minute granules such as sand or stone. The wastewater is channeled to a chamber where to velocity of the water is adjusted so that the grit would settle at the bottom of the chamber. Grit may cause damage to the pumps or other equipment. Grit removal may not necessary in smaller plant. Fat and grease are groups of compounds which are generally insoluble in water. The fat and grease are normally found floating on the surface of the water. In some plants, the fat and grease are removed by using skimmers to collect the fat and grease on the surface of the water in a small tank. However this can also be done in the Primary treatment stage in the same manner. 2) Primary treatment (prepared by Tan HY, 0903497) Primary wastewater treatment is the second step in the wastewater treatment process ahead of the preliminary treatment of a headworks, involves the physical separation of suspended solids from the wastewater flow using primary clarifiers. The objective of primary treatment is the removal of settle able organic and inorganic solids by sedimentation, and the removal of materials that will float (scum) by skimming. Approximately 25 to 50% of the incoming biochemical oxygen demand (BOD5), 50 to 70% of the total suspended solids (SS), and 65% of the oil and grease are removed during primary treatment. Some organic nitrogen, organic phosphorus, and heavy metals associated with solids are also removed during primary sedimentation but colloidal and dissolved constituents are not affected. The effluent from primary sedimentation units is referred to as primary effluent. On the other hand, primary treatment is the minimum level of reapplication treatment required for wastewater irrigation. It may be considered sufficient treatment if the wastewater is used to irrigate crops that are not consumed by humans or to irrigate orchards, vineyards, and some processed food crops. However, to prevent potential nuisance conditions in storage or flow-equalizing reservoirs, some form of secondary treatment is normally required  in  these countries, even in the case of non-food crop irrigation. It may be possible to use at least a portion of primary effluent for irrigation if off-line storage is provided. Primary sedimentation tanks or clarifiers may be round or rectangular basins, typically 3 to 5 m deep, with hydraulic retention time between 2 and 3 hours. Settled solids (primary sludge) are normally removed from the bottom of tanks by sludge rakes that scrape the sludge to a central well from which it is pumped to sludge processing units. Scum is swept across the tank surface by water jets or mechanical means from which it is also pumped to sludge processing units. 2) Secondly treatment (prepared by Harintharan S, 1101379) The secondary treatment in this sewage treatment is one of the most important part in this process. This process is basically designed to remove the waste product from the sewage. This system is also classified as fixed-film  or suspended-growth  systems. The secondary treatment contain a few processes, the 1st process is activated sludge. This activated sludge is majority from the plants which encompass the variety of mechanisms and processes that use dissolve oxygen  to promote the growth of biological flock that substantially removes organic material. This process basically change the ammonia  to  nitrite  and  nitrate  and ultimately to  nitrogen  gas. The 2nd process is this treatment is the Surface-aerated basins also known as Lagoons. This process basically removes the BOD from the sewage water. In an aerated basin system, the aerators provide two functions: they transfer air into the basins required by the biological oxidation reactions, and they provide t he mixing required for dispersing the air and for contacting the reactants (that is, oxygen, wastewater and microbes).However, they do not provide as good mixing as is normally achieved in activated sludge systems and therefore aerated basins do not achieve the same performance level as activated sludge units. The biological oxidation in the Surface-aerated basins is sensitive to the temperature and the rate of reaction increase with the temperature. The suitable temperature for this process is in between  0  °C and 40  °C. Besides that the constructed wetland is one of the process also. This process is a process which cleans the drainage of animals and used to recycle the waste water. The constructed wetland are known to be highly productive systems as they copy natural wetlands, called the Kidneys of the earth for their fundamental recycling capacity of the hydrological cycle in the biosphere and they provide a high degree of biological improvement but depending on design. T he next process is the filter beds which is knows as oxidizing beds are used where the settled sewage liquor is spread onto the surface of a bed made up of  coke, then liquor is typically distributed through perforated spray arms, then distributed liquor trickles through the bed and is collected in drains at the base, and the  biological films of bacteria, protozoa and fungi to reduce the organic content. The next process is the Biological aerated filters are a combine filtration with biological carbon reduction,  nitrification  or denitrification. Its a dual processer in purpose of to support highly active biomass that is attached to it and to filter suspended solids. Carbon reduction and ammonia conversion occurs in aerobic mode and sometime achieved in a single reactor while nitrate conversion occurs in  anoxic  mode. This process is operated either in up flow or down flow configuration depending on design specified by manufacturer. In addition the Rotating biological contactors are the next process in this secondary treatment. This is actually a secondary mechanical treatment system which is capable  of withstanding surges in organic load. The rotating disks support the growth of bacteria and micro-organisms present in the sewage, which break down and stabilise organic pollutants. Oxygen is obtained from the atmosphere as the disks rotate. As the micro-organisms grow, they build up on the media until they are sloughed off due to shear forces provided by the rotating discs in the sewage.   Effluent from the system is then passed through final clarifiers where the micro-organisms in suspension settle as sludge. The sludge is withdrawn from the clarifier for further treatment. After that the membrane bioreactor combine activated sludge treatment with a membrane liquid-solid separation process. The component on this system uses low pressure for microfiltration or ultra-filtration membranes and eliminates the need for clarification and tertiary filtration.   The elevated biomass concentration in the system process allows for very effective removal of both soluble and particulate biodegradable materials at higher loading rates. The final process in this secondary treatment is the secondary sedimentation where the process is to settle out the biological flock or filter material through a secondary clarifier and to produce sewage water containing low levels of organic material and suspended matter. 4) Tertiary treatment (prepared by Raiminder S, 0904743) The main purpose of the tertiary treatment is to ensure that the treated water which is to be released on to the environment is biologically accepted by all other fresh water organisms such as weeds and algae. This part of the treatment includes processes like physical water treatment, lagooning, and excessive nutrient removal processes.to ensure that the discharged water is raised in effluent quality before proceeding to the final stages. In physical water treatment, much of the residual suspended matters are removed using only physical processes such as sedimentation  method and the infamous filtration method. In the sedimentation  method, the water is place in a certain tank to allow all the remaining heaver objects to sink down to the bottom of the container. After few hours went most of the dense object are separated from the water, the cleared effluent or waste stream is removed. Sedimentation is one of the most common methods, quite often used at the beginning and the end of many water treating processes. Another physical method that is commonly used in the sewage water treatment system is the filtration method. In filtration, the water is allowed to pass through filters to separate the contaminating solids from the water. Sand filter is a common filter used in this process. In a number of wastewater treatment methods, semi-solid contaminants like grease and oil are allowed to float on the surface of the wat er, and then they are physically removed. Besides the in lagooning where lagoon is a stationary system having a continuous flow: several ponds working in parallel in which the inlet flow and the outlet flow are equals form lagoon plants. The lagooning technique is a natural and very efficient technique that consists in the accumulation of wastewater in ponds or basins, known as biological or stabilization ponds, where a series of biological, biochemical and physical processes take place. In these ponds or lagoons, certain types of the microorganism are actually supported as these biological agents help in treating the water further by removing the fine particulates. These types of biological ponds are usually classified as anaerobic ponds or oxidation ponds depending on the shape, depth, organic rate, level of treatment of that particular lagoon itself. The excessive nutrient removal is the most viral step in the last stages of the water treatment before the water is released to the environment. When the previously treated water comes to this area of the system, the nutrients level mainly nitrogen and phosphorus in the water is checked. Where when found in excess, the excessive nutrient removal step is carried out. This is because if the unchecked water supply is to be released into the natural water system (river, pond, etc.) it will cause a sudden increase in the native microorganism population of that certain water system. Some of the native microorganisms which are commonly found in ponds today are usually weeds, algae, and cyanobacteria. Therefore, after the sudden rapid grown in the population of these microorganisms, the number of algae for example, becomes unsustainable which causes most of them to die and eventually decay. The following decay process would substantially increase the biochemical oxygen demand (BOD) in that p articular pond, which would cause the other fresh water living organism such as fishes to die as well. Firstly, the nitrogen removal process is carried out. There are various methods of removing nitrogen, each with advantages and disadvantages. However, the biological treatment method is used most commonly. With this method, organic nitrogen and ammonia nitrogen is converted into nitrous and nitrate nitrogen in an aerobic environment, and is dispersed into the atmosphere as anaerobic nitrogen gas. Therefore the gas is removed from the water and released to the atmosphere. And as there is no secondary pollution, this can be called an effective method. In the removal of phosphorus is usually carried out using a method called enhanced biological phosphorus removal (EBPR). The first process in EBPR is the mainstream biological treatment process. Where the utilizing of aerobic and solids separation zones and the provision of return activated sludge are carried out. The next is a first side stream process for anoxic/anaerobic selection of desirable BPR organisms such as the polyphosphate accumulating organisms (PAOs). Finally, a second side stream process serves to ferment organic material in some of the return activated sludge to produce food utilized in the first side stream selection process. The system permits the three processes to be separated from each other by creating two side streams, allowing all three processes to be controlled separately and optimized in satisfying their own specific goals. Besides this biological method, the removal of phosphorus can also be done via chemical precipitation, usually with salts of iron, alu minum, or lime. Chemical precipitation is usually more reliable, easier to operate, and requires smaller equipment footprint than biological removal. But the main back draws of this chemical method is that it may form excessive sludge production as hydroxides precipitates and the chemical used in this method might be considered expensive. 5) Disinfection (prepared by Lim CS, 1001012) The main purpose of disinfection in the wastewater treatment is to provide a degree of protection from contact with infectants and pathogen organisms which will cause waterborne diseases such as cholera, dysentery and hepatitis. Disinfection is also used to reduce the load of microorganisms in the wastewater to be discharged to the environment. Primary, secondary and even tertiary treatments do not fully remove the incoming waste load and microorganisms in the water stream and as a result, many microorganisms still remain in the wastewater. Therefore, various methods of disinfection are introduced such as chemical methods, physical methods and biological methods. The effectiveness of disinfection depends on different factors including the quality of wastewater being treated, disinfectant dosage, type of disinfection being used and others. For instant, cloudy wastewater will not be treated efficiently due to less contact time between ultraviolet light and microorganisms. These microorganisms are shielding by those solid matters in wastewater stream and it reduces the contact time. Generally, long contact times, high concentration of disinfectant and optimum temperature and pH value will increase the effectiveness of disinfection. Chlorination is one of the chemical methods which is commonly used for disinfection in the wastewater treatment. It is widely used through the world due to its low cost and long-term history of effectiveness. Chlorine can be applied in two general ways, liquid and gas. Chlorine in gaseous form is generally added to the wastewater stream rather than liquid form which is also known as hypochlorite because the former costs lesser than the latter. When chlorine dissolves in pure water, hypochlorous acid is formed followed by hypochlorites which are known as free residual chlorines Chlorine is an extremely active oxidizing agent which will react with many other substances in the water stream. For instant, it reacts rapidly with such compounds as hydrogen sulfide, ferrous iron and manganese which found in industrial wastewater. However, if all of the chlorine is consumed in these reactions, no disinfection will result. Hence, to accomplish disinfection, sufficient chlorine is added into wastewater stream to satisfy the chlorine demand and produce residual chlorine which will destroy bacteria. There are few factors which will affect the effectiveness of chlorination. Among the factors are pH, temperature, turbidity, control system and many others. However, chlorination brings some disadvantage to environment. Chlorination of residual organic material can generate chlorinated-organic compound which may be harmful to the environment. Those residual chlorines are toxic to aquatic species; therefore, dechlorination is needed, adding to complexity and cost of treatment. However, chlorination becomes less favoured as disinfectant due to rising cost and it had found to be toxic to aquatic species. As a result, ozone and ultraviolet begin to be used as disinfectant. Ultraviolet (UV) light is more environmental friendly to be used as no chemicals are used and leave no toxic residual. Ultraviolet radiation and damages the genetic material of microorganisms, destroying their ability to reproduce. Before pass through the UV disinfection unit, the wastewater must pass through an advanced pretreatment component. Wastewater flows in the stream parallel to the UV light in a thin film in order to increase the contact time. To increase the effectiveness of the UV light, the UV radiation must come in direct with pathogen organisms and other microbial in the wastewater stream. The effectiveness of a UV disinfection system is affected by few factors including characteristics of the wastewater, the contact time, intensity of UV radiation and many others. Turbidity, flow rate of water stream and suspended solids are also play an important roles in UV disinfection. These factors must be kept at low levels to ensure proper treatment. Disinfection of wastewater, primarily by chlorination, has played an important role in the reduction of waterborne disease. However, there are more new disinfection processes are being developed in order to maximize the effectiveness of disinfection. Role of engineer in this industry The Chemical Engineering is the profession that combines chemistry and engineering concepts that help to solve problems related to world hunger, pollution of our environment, creating new materials, or meeting demands for energy. Chemical engineers develop low cost processes for useful chemical products, which make it possible for both poor nations and the United States to manufacture important fertilizers. The roles of a chemical engineer in waste water treatment have to minimize the waste across the plant or reduction of waste loading to the treatment plant. Other than that, chemical engineer need to state whether its systems for the treatment and reuse of wastewater, process water treatment for industry, high-purity water for sensitive medical or scientific applications, or systems to supply clean drinking water to people and their families. Besides that, as a chemical engineer also responsible for providing expertise in their respective discipline as it applies to the hazard analysis of the process being studied. Therefore, we also in charge for attending the initial hazard analysis kick-off meeting. On the other hand, we are also required to be available to the team as required with the understanding that the team leader will give adequate advance notice when their expertise is required. Lastly we are necessary to provide documents of any existing safeguards and procedures. Skills/ knowledge required Many types of skills and knowledge are required for chemical engineer in waste water treatment. They required intensive knowledge in wastewater treatment technologies, so that they will more easy to solve the problems when they face the difficulty. On the other hand, they also need expertise in equipment design, influent water treatment, effluent monitoring, and wastewater recycling. In addition, proficiency in computer, programming, modeling and data analysis, for example AutoCAD, Microsoft Office, FOTRAN, Origin, Maple, Polymath, and other software are also the knowledge needed for chemical engineer. Moreover, strong technical writing, presentation, and project management skills are also useful skill for chemical engineer in order to present the researches after they have completed. Besides the skills at above the hazard and operability study (HAZOP) technique also needed for a chemical engineer working in industry. The HAZOP technique is most popular in most industry because that is technique which is structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent efficient operation. Otherwise, HAZOP as well a qualitative technique based on guide-words and is carried out by a multi-disciplinary team (HAZOP team) during a set of meetings.
