Ethical Violations Coursework Example | Topics and Well Written Essays - 250 words

Ethical Violations - Coursework Example According to the leader, the role was more suitable for ladies than for men and so instead of promoting the employee to take up the position, he employed a new person to take up the position. This was immediately identified as ethical violation because the labor laws of the country frowns on discrimination of any type (Johnson, 2012). The consequence of the violation on the leader who committed the violation was that he had to personally face a series of legal suits. This is because the employee involved suited the company and as the leader, the one who violated the ethics had to take off precious hours off his work schedule to attend to the court. All in all, it would be stated that accountability becomes deeply affected when such violations occur. This is because in the present circumstance, it became highly difficult for other employees of the company to trust the credibility of the leader to ensure fairness. The workforce also came to adopt a notion that the worker had taken issues of accountability into his own hands and so the larger workforce could not trust his credibility to be accountable (Wade et al, 2009) Wade, N. G., Worthington, E. L., Jr., & Haake, S. (2009). Comparison of explicit forgiveness interventions with an alternative treatment: A randomized clinical trial.

Communication Technologies Essay Example | Topics and Well Written Essays - 3500 words

Communication Technologies - Essay Example Then the ethical side of the matter is discussed. Two theories are drawn (Utilitarian and Kantian) to find out is it moral to monitor company's personnel. The third part of the paper is devoted to social responsibility. It is argued that a widespread use of monitoring techniques that intrude into employees' private life indicates the low level of social responsibility among employers, which in fact damages their own business. The section also brings recommendations on how to improve privacy preservation within the company and explains what benefits a company will receive. As the communication technologies continue to develop, the topic of workplace privacy becomes increasingly important. A hundred years ago manager was able to monitor his subordinates only through visual observation and mail check, if a business was related to frequent use of post services. Later, with the spread of telegraphic communication the tension of employers rose up, although it was still very hard for employees to misuse business channels for private purposes. Thus, there was little need in monitoring the use of business communication by personnel. Everything has changed with the development of phone, and later, e-mail. With the ease of access to better methods of communication, employers often use the chance to monitor their employees' activity, justifying their actions as concern for productivity. From the employees' side the monitoring of their phone calls and e-mail messages on the workplace is often perceived as the intrusion into privacy. Consequently, complaints of em ployees drive them to court bringing suits against their employees. So far most of such cases were resolved in favor of employers, as can be seen from examples illustrated later in the paper. The legal side of the matter of workplace privacy is observed in the next section. Law is on the Employer's Side Most of the developed Western countries have a twofold legislation on the monitoring of employees' workplace activity by employers. For example, in the US interception of wire and electronic communications is prohibited (Electronic Communication Privacy Act, 18, USC 2511, 1986). However the same law has some exceptions, allowing employers to monitor business phones and emails of their employees in most of the cases: It shall not be unlawful under this chapter for a person acting under color of law to intercept a wire, oral, or electronic communication, where such person is a party to the communication or one of the parties to the communication has given prior consent to such interception. (Electronic Communication Privacy Act, 18, USC 2511, 1986) Prior consent may be given each time an employee uses communication devices, or implied. Nevertheless, "the fact that an employee merely knows that the employer has the capability to monitor telephone conversations is not sufficient to establish implied consent" (Nuterangelo, 2004). An employee must be aware of monitoring. Therefore, every employee that uses communication services belonging to employer is in the same 'party' with his employer, allowing him to intercept every message or call. Moreover, each employee that was informed in some way (e.g. contract agreement) of using work phones or computers for

Varieties of Market Segmentation

Varieties of Market Segmentation MARKET SEGMENTATION Market segmentation is the process of categorizing the market into several groups on the basis of various factors such as demographic, geographic, psychological, and behavioral factors. This is to ensure that the marketers can understand their target audience better so as to make the marketing more effective and get more satisfied customers. Thus, the marketers can gain a great advantage over the competitors. There are different ways by which market segments can be categorized. It can be done by categorizing the preferences of the consumer. Based on this, market can be categorized as homogeneous preferences, diffused preferences and clustered preferences. In homogeneous preferences the customers roughly have the same preferences whereas it varies in case of diffused preferences. When a group of consumers have shared preferences it leads to the formation of natural market segment which refers to clustered preference. While marketing a product three areas of marketing must be taken into consideration, i.e, mass marketing, product differentiated marketing and target marketing. Mass marketing takes into account mass producing, mass distributes and mass promotes on product to all buyers. It is important to realize the great variety in individual customers and therefore the marketers use this type of segmentation to customize their marketing programmes for each customer. In product differentiated marketing more than one product with different features, style, size, and quality is introduced. In target marketing, on the basis of the market segments the products are developed and customized. Market segments can be differentiated in various ways. Some of them are demographics, geographics, psychographics and behavioural segmentation. Demographic segmentation Demographic factors are age, gender, income, occupation, education, religion, generation, nationality, family size, family cycle, social class etc. Based on these demographic values, the customers are divided into various segments. This type of segmentation is suitable because the variables are easy to measure and as they provide description of the target customers therefore media buyers and others can target a desired target market. Some of the important variables while segmenting markets are: Age and Life cycle segmentation As the desire and need of customer change with their age therefore age and life cycle is a good factor in order to determine marketing approach. One of the examples is of a 70 year old person using landlines instead of mobile phones due to lack of technological knowledge. Therefore marketers need to take this into consideration and guard against stereotypes. This can also be associated with buying pattern and behavioural characterstic. For example, as married people have various economical obligation therefore they tend to spend less on luxury items whereas on the contrary, single people tend to purchase new fashionable items as they don’t have such economic obligations. Gender Segmentation As the needs and wants of men and women are different therefore gender segmentation is being applied from a long time in terms of clothing, hairstyle, magazines, cosmetics. But the marketers must not define a product as being masculine or feminine as metro sexuality has become a common gender-factor. Income Segmentation This type of segmentation can be seen in automobiles, financial services, travel, clothing, and cosmetics. Usually the high income customers are the target but it should be considered by the companies that just the income cannot be suitable criteria to determine the customer as they might have different preferences and priorities while selecting a product. Even the lower income groups are targeted as the competitive pressure reduces and the consumer loyalty is gained. Generation Segmentation Various significant events, many a times characterize a particular period. These influential factors can be music, politics, movies etc. Therefore the marketers must make use of the images and icons of a particular generation in order to market their product. Social class Segmentation Most of the companies design their product for a specific social class. It divides the customers on the basis of their preferences towards cars, clothing, leisure activities, home furnishing, retailers, reading habits etc. Demographic segmentation thus assumes that people with different backgrounds and other differences are likely to share same values and behaviour. Geographic Segmentation In this method of segmentation, customers can be categorized on the basis of countries, nation, state, region, city, and neighborhood. But a company must consider the fact that the data might vary due to population shift. Various sales and purchases are based on the geographical variables as the purchasing behaviour of the customers are influenced on where they live or work. Sometimes there are also differences in the location where the product is marketted due to cultural factors, tradition, politics. These differences can be significant in one segment whereas in other segments there might just be minor differences. Globalization plays a major role in linking socio economic and demographic characteristics. This type of segmentation is referred to as geodemographics. It therefore combines the target customers with where they live. Instead of comparing the consumers by their occupation, the consumers are compared on the basis of where they live, hence the companies are more capable of predicting consumer behaviour. Psychographic Segmentation There are two types of customers, personality profiles and lifestyle profiles. The psychological variables provide the marketer opportunity to get additional information about traditional, geographical, demographic bases like sex, age, income. Psychological profiles are often used as a supplement to geographics and demographics. Therefore on the basis of their attitude, values, lifestyles, interests and opinions people are divided in psychographic segmentaton. Behavioural Segmentation There are various behavioural variables such as occasions, benefits, status, usage rates, loyalty, attitude, buyer readiness (which will be discussed in detail) which determine behavioural segmentation .These variables are considered the best starting points in constructing market segments which are mainly based on the customers attitude towards the use and response to a product. Occasions Customers are divided into segments according to the time on which they get the idea to buy a product. The time can be a day , a week, a month or an year. An example for this situation is the variation in market strategy for Christmas and Valentines day. Benefits As different kind of people look for different benefits in the same product, this segmentation divides the customers based on this. People tend to look for the benefits provided by different brands and accordingly they make their choice. Here casual factors play a major role rather than descriptive factor like demographics. User status This type segmentation is done on the basis of the category of users , i.e potential users, non users, ex-users, first time users, regular users etc. The marketing approach varies according to the type of users. Usage rate Based on the usage of the product, the customers are divided into various segments like non users, heavy, medium, light product users. The basic strategy followed by the company is to target one heavy user instead of several light product users because the heavy users account for a high percentage of total buying although they constitute a small percentage of the market. But the other users must not be neglected as even they may provide better future prospects. Usage rate further divides the customer according to time which means that the product to be sold may vary according to time. Buyer readiness stage It depends on the factors such as people’s awareness and interest in the product. A person might be aware of the product and he also may not be. The difference lies in whether they are just informed about the product or interested in buying the product or they desire to buy the product or just intend to buy the product. In all the cases, a customer must be lead along so that he finally gets convinced to buy the product. For example, a person belonging to a different place might not be aware of the products particularly sold at one place hence the marketing strategy should be different at that place and the product should be promoted more. Loyalty status Based on the loyalty of the customers, they can be categorized as hard core loyals, split loyals, shifting loyals and switchers. Hard core loyals tend to stick to a particular brand for a long period of time without even considering other brands. Split loyals have preference towards two to three brands and they keep switching in these. Shifting loyals stay with a particular brand for some time and then change it. Switchers do not have any specific choice and they keep changing the brands from time to time. Attitude People can have an enthusiastic, indifferent, positive, negative, or hostile approach towards a product. Based on these factors people can be divided into various segments and hence the company can get a good idea of the market and the strtegy to be followed. To improve the targetting strategies and get a clear picture of the market, it is important for the marketers to combine different behavioural variables. A marketer must reach all buyers in all segments by defining its target audience. By taking into account various concepts such as demographic segmentation, geographic segmentation, the psychographic segmentation and the behavioural segmentation, a company must decide which is the most appropriate concept while designing the market strategy. For example , demographic and behavioural segmentation are the most appropriate one’s while designing market strategies of a telephone as the ages of the customers is an important factor. Apart from age, attitude is also an important factor. Once the target customers have been defined, the next step is to evaluate the market segments and decide in which segments the marketing strategy should be directed. Market targeting is the second stage of the segmentation process.

In this process by means of rotation of the bio wheels micro organisms are expected to growth in the RBC and the overflow from the Lamella clarifier will be the first stage of the treated water. The micro organisms will develop on the surface of the disk and the colonization of the organisms will take place because of the inlet load into the system. The thick film like formation in the surface of the disk is the indication of the growth. In Sewage water the main constituents of Pollutants being organic in nature these can be digested easily in the RBC. Sewage is created by institutions, residences, and hospitals and commercial and industrial establishments. Raw influent of sewage wastewater includes household waste liquid from the toilets, sinks, showers, kitchens, baths, and so forth that is disposed of sewage waste water. 1.1 Aim: The aim of the project is to Analysis of water consumption and power consumption of sewage treatment plant. 1.2 Objective: * To Analysis the water and power consumption of the sewage treatment plant * To vary the parameters of water source, power source. * To Analyze the Rotating Biological contactor Biowheels.Lamella clarifier * Analyzing 2D design of the Sewage Treatment Plant. * To analyze the results and propose appropriate solution. 2. BACKGROUND RESEARCH: Waste water collected from domestic and industrial communities must be returned to receiving waters or to the land. Although the collecting of storm water and drainage dates from ancient times the collection of waste water can be traced only to the early 1800s. The systematic treatment of wastewater followed in the late 1800s and early 1900s. There are many methods and processes to treat wastewater. The most common approach uses primary treatment (screening and clarification) to remove solids; aerobic, suspended growth, activated sludge secondary treatment to reduce organic pollutants; and chlorine disinfection to reduce pathogens. Secondary treatment is the largest energy consumer (30 to 60% of total plant usage), followed by pumping and sludge processing. Although suspended growth, activated sludge is the most common wastewater treatment process, it is not the most energy efficient. Aerated lagoons, trickling filters and rotating biological contactors are significantly more efficient. They are not as widely used because aerated lagoons require a large land area, and trickling filters and rotating biological contactors are better suited for smaller capacity applications. Many wastewater treatment plants are shifting from chlorine-based disinfection to UV disinfection to eliminate the risk of storage and handling of toxic chemicals. Although UV disinfection is energy intensive, it adds no chemical residue to the effluent. This feature is particularly important for discharge to sensitive aquatic environments or for wastewater reuse. In general, low pressure UV systems are substantially more efficient than medium pressure systems. Energy efficiency opportunities in wastewater treatment include the use of fine bubble diffusers, dissolved oxygen control of aeration, high efficiency blowers, variable frequency drives on pumps and blowers, premium efficiency motors, and the reduction of the head against which pumps and blowers operate. Sewage is generally a mixture of domestic of waste water from bath, sinks and washing machines and toilets, waste water from all industry and rainwater runoff from roads and other surfaced areas. Every day in the UK about 347,000 Kilometers of sewers collect over 11 Billion liters of waste water. This is treated about 9000 sewage treatment works before the treated effluent is discharged to inland waters, estuaries and the sea. Without suitable treatment, the waste water we produce every day would damage the water environmental and creates to affect the public health problems. Untreated sewage contains organic matter carbohydrates, fats and proteins, bacteria and chemicals. Bacteria naturally present in environmental waters do break these substances down, but in doing so they use the oxygen dissolved in this water. If there were large or continuous untreated discharges of urban waste water the result could be too little oxygen for fish and other aquatic life to survive. So the purpose of waste water treatment is to remove organic substances to protect the environment from these effects. Sewage works therefore reproduce what would be occurring in the environmental. Settling out much of the solid matter is called Primary Treatment, and using Bacteria that digest and break down the organic substances is called Secondary Treatment. Sometimes further treatment Tertiary is required to protect sensitive water environments; Tertiary treatment can involve disinfecting the treated effluent to protect the bathing and shellfish waters. It can also involve the removal of phosphorous or nitrates nutrients present in sewage. To protect the waters that is threatened by eutrophication.

Domestic water normally used for sanitary and general purposes 2. Industrial water used for nondomestic purposes, 3. The Public service water normally used for fir fighting, and system maintenance and also municipal landscape irrigation. 4. Unaccounted for system losses and leakage The following data are typical municipal water use in the United States Report. ( (George Tchobanoglous and Franklin L. Burton, 1991) Table 1 Municipalities water use 3.1 Domestic water use:. Domestic water use encompasses the water supplied to residential areas ,and commercial districts, institutional facilities, and recreational facilities as a measured by individual water meters .The uses to which this water is put include drinking, washing, bathing, culinary, and waste removal, and yard watering these kind of water collected from household sewage. Using the average flow values reported in above table of the water used in a municipal water supply system is for domestic purposes. 3.2 Residential areas: The water normally used by residential households consists of water for interior use such as showers and toilets and water for exterior use such as lawn watering and car washing, the household wastewater mostly used in sewage treatment plant. Typical data for interior water use are presented in below table. How much amount of water used in residential areas water use for exterior applications varies widely depending upon the geographic location, climate and time of year and mainly consists of landscape irrigation. The Residential areas 100% of water normally used by typical distribution of residential interior water use the following table given details Table 2 Typical distribution interior water use (George Tchobanoglous and Franklin L. Burton, 1991) 3.3 Commercial facilities: The water used by commercial facilities for sanitary purposes will vary widely depending on the type of activity means example of offices and compared to a restaurant. Typical water use values for various types of commercial facilities are reported in following table also for large commercial water using facilities such as laundries and car washes, careful estimates of actual water use should be made. Table 3 Typical rates of water use for commercial facilities (George Tchobanoglous and Franklin L. Burton, 1991) 3.4 Institutional facilities: Water used by facilities such as hospitals, schools and rest home is usually based on some measure of the size of the facility and the type of housing function provided example of per student or per bed, and water normally use for schools will vary significantly depending on whether the students are housed on campus or are day students. The representative water use values for institutional facilities are reported following table. Table 4 Typical water-use values for institutional facilities (George Tchobanoglous and Franklin L. Burton, 1991) 3.5 Recreational Facilities: The recreational facilities mostly water used in such as swimming pools, bowling alleys, and camps, resorts, then country clubs perform a wide range of functions involving water use. The following table typical water use values are reported. Table: Typical water-use values for recreational facilities (George Tchobanoglous and Franklin L. Burton, 1991) 4. SEWAGE TREATMENT PLANT: 4.1PRINCIPLE: Sewage treatment plant there are two main types of biological reaction, depending upon the presence or absence of free oxygen, the aerobic reaction takes place only in the presence of free oxygen and produces stable, relatively inert end products. Anaerobic reaction are more complex, being two stage, proceeding relatively slowly and leading to end products which are unstable and which still contain considerable amounts of energy. In any biological reaction the energy in the organic matter, used as food by the microorganisms, is split three ways; some is used in creating new microorganisms, some is incorporated in the end products of the reaction, the proportions of energy in the three areas depend upon the nature of the reaction, the type of organic matter, the type of microorganisms,and environmental conditions. The organic matter in wastewater thus provides the well as providing the energy for the oxidation reactions which releases the end products of biological treatment. (THY Teb butt,1990). Domestic sewage satisfies all these requirements but some industrial wastewaters may be lacking in nutrients or other factors, which could result in inhibition of biological activity, Toxic substances present in the wastewater can also mean that biological treatment of an organic wastewater is ineffective, although it is sometimes possible for microorganisms to become acclimated to substances which initially appear to be toxic. The aim of conventional biological treatment processes is to achieve almost complete removal of the organic matter in the feed. The activated sludge system is a common form of dispersed growth reactor, and both systems require a settling facility to remove the excess biological solids produced in the process. In the case of fixed film systems the solids are essentially dead cells, but with the dispersed growth activated sludge systems the bulk of the cells are living and are returned to the reactor for re use, only the excess solids being removed. (THY Tebbut t,1990). Characterstics of waste water sewage treatment plant:  · Bio chemical oxygen demand  · Total dissolved solids  · Chemical oxygen demand  · Total suspended solids  · PH  · Bio chemical oxygen demand: It is a measure of the amount of oxygen that bacteria will consume while decomposing organic matter under aerobic conditions.  · Total dissolved solids: It comprises inorganic salts and small amounts of organic matter that are dissolved in water. The principle constituents are usually the captions , calcium, magnesium, sodium, and potassium and the anions carbonate, bicarbonate, chloride, sulphate and particularly in groundwater nitrate.  · Chemical oxygen demand: It is a measure of the total quantity of oxygen required to oxidize all organic material into carbon dioxide and water. * Total suspended solids: It is a measure of the suspended solids in waste water, effluent, or water bodies determined by tests for Total suspended non-filterable solids.  · PH: It is a measure of the acidity or alkalinity of a solution numerically equal to 7 for neutral solutions increasing with increasing alkalinity and decreasing with increasing acidity. The PH scale commonly in use ranges from 0 to 14. ( www.answers.com ) Classification of Waste Water Treatment Methods The wastewater treatment is contaminants are removed by physical, chemical and also biological methods. Sewage Treatment Plant individual methods usually are classified as a physical unit operations, chemical unit operations and also Biological unit operations and processes. Although these operations and processes occur in a variety of combinations in Treatment Systems. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972) 4.2 Physical operations unit: The Treatment methods in which the application of physical forces to predominate are known as physical operation unit. Because most of these methods involved directly from the first observations of a nature, and they were the first to be used for wastewater .treatment. These are the Screening, Mixing, Flocculation, Flotation,sedimentation,Filtration,and Gas transfer are typical unit operations. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972). Screening: The first off all unit operation entered in wastewater treatment plants is screening .a screen is a device with openings ,generally of uniform a size, that is using to retain the coarse solids found in wastewater. Description: The screening elements may consists of parallel bars, wires or ,grating, rods, mesh, or perforated plate ,a screen composed of parallel bars or rods is called a bar rack sometimes called a bar screen). The term screen is used for screening devices consisting of perforated plates wedges wire elements and wire cloth. The materials removed by these devices are known as screenings. Bar Racks: In Wastewater treatment, bar racks are used to protect the Pumps pipelines valves and other appurtenances from the damaged or clogging by a rags and large objects. Screens: Sewage treatment plant is widely used to Barscreening,early screens were of the inclined disk or drum type, whose screening media consisted of bronze or copper plates with milled slots ,and were installed in place of sedimentation tanks for primary treatment .since the early 1970s,there has been resurgence of interest in the field of wastewater treatment in the use of screens of all types ,the application range from primary treatment to the removal of the residual suspended solids from biological treatment processes. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972) Mixing: Mixing is an important unit operation in many phases of wastewater treatment including (1)the mixing of one substances completely with another, (2)the mixing of liquid suspensions,(3)the blending of miscible liquids,(4)flocculation and (5)heat transfer .chemicals are also mixed with sludge to improve tidal watering characteristics. In anaerobic digestion, mixing is used accelerate the biological conversion process and to heat the contents of the digester uniformly . Description Apparatus: Most mixing operations in wastewater can be classified as continuous rapid or continuous. Continuous -rapid mixing is used most often where one substance is to be mixed with another. Continuous mixing is used where the contents of reactor or holding tank or basin must be kept in suspension. Energy dissipation mixing: The power input per unit volume of liquid can be used as a rough measure of mixing effectiveness, based on the reasoning that more input power creates greater turbulance,and greater turbulence leads to better mixing. Sedimentation:: It is one of the most widely used in waste water treatment, sedimentation is the separation from the water, by gravitational settling, of suspended solids that are heavier than water, it is one of the most widely used unit operations in wastewater treatment .A Sedimentation basin may also be referred to as a sedimentation tank, settling basin ,or settling tank, Sedimentation is used for grit removal, particularly floating matter removal in the primary settling basin, biological float removal in the activated sludge and settling basin and chemical flog removal. Whenever the chemical coagulation processes is used. 4.3 Chemical unit processes: Sewage treatment plant is widely used to chemical unit processes ,This Treatment Methods in which the removal or conversion of the contaminants is brought about by the chemicals or by other chemical reactions are known as a chemical processes unit. There are three different types chemical processes used in the wastewater treatment.Precipitation,and disinfection and adsorption, which the process mostly used in the wastewater treatment. In the chemical precipitation ,treatment is also accomplished by producing a chemical precipitate that will settle. In most cases the settled precipitate will contain the both constituents that may have reacted with the adding to chemicals and the substance that were swept of wastewater as the predicated settled in the water. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972) 4.4 Chemical coagulation: The settlement of fine colloidal and suspended solids can be assisted by the use of flocculation as but with dilute suspensions, such as lowland river waters, the opportunities for collisions and agglomeration are limited. In such circumstances flocculation does not significantly improve the settling characteristics of the suspension. the addition of a chemical coagulant, which precipitates flocculent solids in the water, followed by flocculation and sedimentation, can provide a high degree of clarification. the processes of chemical coagulation is thus carried out in a sequence of operations, the first of which involves rapid to permit enmeshment of the colloidal solids in the rapidly precipitating flock. (THY Tebbutt, 1990) Following the initial stage precipitation stage, the suspension is passed to flocculation and sedimentation units, which may be separate or combined. the most popular coagulant for potable water treatment is aluminum sulphate, often referred to as alum. When it is added to water in small doses of around 20-50mg/l,a reaction takes place with the natural alkalinity present, and insoluble aluminum hydroxide is formed. this responds well to controlled flocculation. The chemical reactions which occur are complex but may be simplified as Al2(SO4)3 +3Ca(HCO3)2 = 2Al(OH)3 + 3CaSo4 +6CO2 When using the commercial alum which has 16-18 molecules of water of crystallization, and expressing alkalinity in terms of calcium carbonate, each mg/l of alum reacts with 0.5mg/l of alkalinity. By using a range of coagulant does and PH values ,it is possible to determine the optimum conditions to achieve the required water quality. (THY Tebbutt, 1990) Chemical precipitation: In essence ,chemical precipitation depends upon the use of an added reagent which combines with the impurity to be removed to give an insoluble product which can then be removed by sedimentation, preceded by flocculation if necessary. A(impurity) + B(reagent) = C (precipitate) + D(by product) It is clearly essential that any byproduct of the reaction does not itself have undesirable properties in relation to the eventual use of the water or wastewater. It is also important to remember that chemical precipitation processes produce sludges containing the impurities and that the cost of handling and disposing of these sludges in a safe manner can be significant. (THY Tebbutt, 1990) Disinfection: Disinfection refers to the selective destroy of disease causing organism .all the organisms are not destroyed of during the process; this differentiates disinfection from sterilization, which is the destruction of all organisms. In the field of waste water treatment, there are three categories of human enteric organisms of the greatest consequence in producing disease are viruses, bacteria, and amoebic cysts. Disinfection is widely used to wastewater sewage treatment plant; there are well -established links between the contamination of drinking water with facial matter and the incidence of such water related diseases as cholera, typhoid and many gastrointestinal infections. Thus the removal of the pathogenic microorganisms from water supplies is a very valuable measure for the improvement of public health. Disinfection means the destruction of pathogenic microorganisms and does not necessarily mean that the water is sterile, since a small number of harmless microorganisms are usually present in tap water and poses no hazard. For most disinfection the rate of kill is given by dN/dt = -KN where k = rate constant N = number of living microorganisms The rate constant varies with the particular disinfectant, its concentration, the organism being killed,PH,Temperature,and other environmental factors. (THY Tebbutt, 1990) 5. Biological unit processes: Sewage Treatment plant is widely used to Biological unit processes ,this is processes is remove the microorganism of the water, In this Treatment methods in which the removal of contaminants is bring about by biological activity are known as a biological unit processes. Biological treatment is used primary to remove the biodegradable organic substances matter (means colloidal or dissolved )in wastewater.Basically,these substances matter are converted into the gases that can be escaped to the atmosphere and into the biological cell tissue unit that can be removed by settling. At the same time this treatment is also used to remove the nutrients (means nitrogen and phosphorous) in wastewater. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972) 5.1 Components of wastewater Flows The components of the wastewater flows that make up the wastewater flow from a community depend on the type of collection system used and may include the following: There are four types of wastewater flows available in the wastewater treatment. 1. Domestic (is also called sanitary) wastewater. This is kind of wastewater discharged from residences and from commercial,instutional , and house hold sewage toilet waste water, bath, sinks ,and canteen wastewater and similar facilities. 2. Industrial wastewater .this kind of wastewater in which industrial wastes predominate. 3. Infiltration/inflow .water that enters the sewer system through the indirect and direct means. The Infiltration is extraneous water enters that the sewer system through the leaking joints. 4. Storm water. Runoff resulting from rainfall and snowmelt. This kind of components of wastewater flows essentially used in the sewage treatment plant. 5.2 Waste water treatment: There are four different types of wastewater processing in available in sewage treatment plant. Primary treatment referred to physical unit operations. Secondary treatment referred to chemical and Biological unit process, and also Advanced or tertiary referred to combinations of all four other processing.  · Preliminary wastewater treatment: Preliminary wastewater treatment is defined as the removal of wastewater constituents that may causes to maintenance of the operational problems with the treatment of the operations. Examples of preliminary operations are screening and commutation for the removal of debris (J.Staudenmann, A. Schonborn, C. Etnier, 1996).primary wastewater treatment: In primary wastewater treatment, a portion of the suspended solids and organic material is removing from the waste water. This removal is usually accomplished with physical operations such as screening and sedimentation. The effluent from primary treatment will ordinarily contain considerable organic matter and will have relatively high BOD.treatment plants using only primary treatment will be phased out in the future as implementation of the EPA secondary treatment requirements is completed. Rare instances (for those communities having a secondary treatment waiver)will primary treatment be used as the sole method of treatment .the principal function of primary treatment will continue to be as a precursor to secondary treatment . * Conventional secondary wastewater treatment: The secondary treatment is directed principally toward the removal of bio degradable organics and suspended. Disinfection is included frequently in the definition of conventional secondary treatment is defined as the combination of processes customarily used for the removal of these constituents and includes biological treatment by activated sludge fixed film reactors, or lagoon systems and sedimentation.  · Advanced wastewater treatment/wastewater reclamation: Advanced wastewater treatment is defined as the level of treatment required beyond conventional secondary treatment to removing constituents of concern including toxic, nutrients, compounds, and larger amounts of organic material and suspended solids .In addition to the nutrient removal processes, unit operations or processes frequently employed in advanced wastewater treatment are chemical coagulation, flocculation, and sedimentation followed by filtration and multi grade filter and also activated carbon filter. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972). 6. STP BASED ROTATING BIOLOGICAL CONTACTORS: 6.2 Principle: A Rotating biological contactor (RBC) is constructed of bundles of plastic packing attached radically to a shaft, forming a cylinder of media .the shaft is placed contour bottomed tank so that the media are submerged approximately 40 percent. the contactor surfaces are spaced so that during submergence in wastewater can enter the voids in the packing .when rotated out of the tank ,the liquid trickles out of the voids in the packing. when rotated out of the tank the liquid trickles out of the voids between surfaces and is replaced by air. A fixed film biological growth, similar to that on a trickling filter packing, adheres to the media surfaces. Alternating exposure to organics in the wastewater and oxygen in the air during rotation distributor. Excess the biomass sloughs from the media and is carried out in the processes effluent for gravity separation. A treatment system consists of primary sedimentation preceding and final sedimentation following the rotating biological contactors. Since the recirculation through RBC units is not normally practiced, only sufficient underflow from the final clarifier is returned to allow removal of excess of the biological solids in primary sedimentation and waste sludge similar to the character to the from trickling filter plant ,in withdrawn from the primary clarifiers disposal of waste. In large type of plants, a common shaft is placed over a contoured tank with the wastewater flow parallel to the shaft. A series of four stages are normally installed in the treatment of domestic wastewater for BOD reduction. additional stages may be added to initiate nitrification .Each stage acts as a completely mixed chamber and the movement of the wastewater through the series of tanks simulates plug flow. Biological solids washed off of the media are transported hydraulically under the baffles to be carried out with the effluent.RBC units are protected by installation either in a building with adequate ventilation or under separate plastic covers lined with insulation. The efficiency of BOD removal of in the processing domestic wastewater is based on empirical data from operating RBC plants. the Mathematical equations also have been developed ,but their prediction of the performance is not consistently reliable. the typically recommendations for secondary treatment of domestic wastewater to produce an effluent of less than 30 mg/l of BOD and also 30mg/l of suspended solids.

ROTATING BIOLOGICAL CONTACTOR PROCESS(60 KILO LITRE PER DAY): 2D 8. WATER CONSUMPTION ANALYSIS OF SEWAGE TREATMENT PLANT: Raw sewage characteristics: Domestic waste water: The volume of a wastewater from a community varies from 50 to 250 gal capital per day depending on the sewer system uses. A common values for domestic wastewater flow is 120 gpcd means 450 liter person per day use, which assumes that the residential waste water have modern water using appliances, such as automatic washing machines. the organic substances matter contributed per person per day in domestic wastewater is approximately 0.24 lb to 110gram of suspended solids and 0.20lb and 90 gram of BOD in communities where a substantial portion of the household kitchen wastes is designed is discharged to the sewer system through garbage grinders. In selection of data for design, the quantity of and organic strength of wastewater should be based on actual measurements taken through the year to account for variations resulting from seasonal climatic changes and other factors. the average values during the peak month may be used for design ,excluding un usual infiltration and inflow, the av erage daily sanitary wastewater flow during the maximum month of the year is commonly 20 to 30 percent greater than the average annual daily flow, excluding seasonal industrial wastes, the average daily BOD load from sanitary wastewater during the maximum month is greater than the annual ave
