Water Treatment

...Name: Professor: Course: Date: Water Treatment, Desalination Water is an essential natural resource with a wide range of functions. Water treatment is a process aimed at purifying water for either consumption by human beings and animals or for irrigation. Several processes are applied during water treatment. Desalination is a process of removing salt and other chemicals from sea water. The process is complex with varied economic benefits, environmental and health impacts, and social impact as exemplified by this essay. Desalination involves separation of dissolved salts from brackish, wastewater, wells, industrial feed and sea water. The process of desalination is referred to as reverse osmosis. Water is forced to pass through semi-permeable membrane. Energy is required to enable water passage through the membrane. Reverse Osmosis uses stainless steel pipelines that are extensively iron based. An ancillary equipment is availed in accordance with the chloride concentration in each case. For the low levels of chloride, stainless steel pipe systems are applied. In the case of highly corrosive resistant materials, either super- austenitic materials or duplex stainless steels are used to handle high levels of chloride. Nanofiltration (NF) and Reverse Osmosis are the prevalent membranes driven by pressure. They removes salt and other impurities. The cost of desalination is high because it uses advanced technology that is applied by skilled personnel. It is an...

Application Essay

...Writing Your Graduate School Application Essay Generally speaking, there are two types of application essays for graduate school: the statement of purpose (SOP) and the personal statement. (Refer to FAQs to find out how the two types are different.) Both types let you convince the admissions committee that you are a good fit for the program and can contribute to the department. Although different graduate schools may ask you to answer different prompts, most ask that you write no more than a two-page application essay. The application essay is difficult to write because you must pitch your candidacy to a few department faculty members who read through hundreds – or sometimes thousands – of other essays. In this handout, you will learn how to show these busy readers that you will contribute meaningfully to the university and their department. 1. Relate your past and present experiences to the future. In their application essays, many applicants make the mistake of underemphasizing the future. But it’s important that you show how your past experiences have informed your present work, and how your present work can be extended to the future or raise new research questions. Admissions committees assess many qualified applicants based on whether their research will reflect positively on the university and their department. Committees will think your past and present work is relevant only if it relates directly to your plans for the future. If you don’t know exactly where your......

...Zack Messmore MLA Format Theo 201-B23 Christology In the branch of natural science called thermodynamics which deals with energy and how energy worsd, there is a term called “triple point” Triple point in simplified terms refers to the point at which a substance reaches a specific temperature and pressure which enables it to be gas, liquid, and solid. A popular example of this is water, which has a specific triple point of 273.16 K. At this point the water, is a gas (water vapor), a liquid (water), and a solid (ice). (Çengel 135) This all happens at a microscopic level and at fractions of milliseconds, and yet it is the best real life example of how anything can be three things at once. God may have included this little element in earth science while creating the world to reflect on his true nature. This scientific fact could be a great way to defend the idea of how Jesus could be both God and Man. However as with most of the bible faith plays and biblical evidence plays a large roll. Good information on thermodynamics, however also make sure that your introduction fully introduces all of the topics that your work intends on addressing. The Bible makes unambiguous claims as to who and what Jesus was. Jesus claims several times throughout his walk on earth that he was in fact God and that he existed before the time of the decibels. He alludes to Exodus by saying "before......

..."Choose a medical condition that interests you and research it. Write about the possible uses of hypnosis in the treatment of the condition as you see them. Induction I have choosen to look at eczema for this essay. It is something that affects me personally. Eczema is a fairly common skin condition. It is an innflamation of the upper layers of the skin. It is seen mostly in children and affects around 1 in 12 adults. There does seem to be a link between eczema, hay fever and asthma, and as yet there is no known cure for it. Atopic eczema is a genetic condition based on the interaction between a number of genes and environmental factors. In most cases there will be a family history of either eczema or one of the other ‘atopic’ conditions i.e asthma or hay fever. The symptoms of ezcema can vary from being dry, itchy and inflamed to being broken and bleeding and raw. Ezcema is linked to stress levels in people and people who suffer with ezcema can develop anxiety around the way it looks and disfigures the skin, which in turn creates greater stress levels and ultimately leads to the eczema getting worse. It can be a viscious cycle. There is not a lot of research done into the power of hypnosis and other therapies such as meditation linked to eczema. The word eczema comes from the Greek word “ekzein” which means “to boil". The most successful treatment with eczema is steriod creams and ointments, one of the main problems with eczema is its extrememly itchy and......

...time. The agent that causes TB is mycobacteria such as Mycobacterium tuberculosis. Mycobacteria can be found easily in the environment such as soil and water but M. tuberculosis can only survive in its human hosts. About one-third of the human population has tuberculosis. This highly contagious disease is spread through droplets in the air when an actively infected person coughs, spits, talks, sings, or sneezes and an uninfected person is close and catches the bacteria by inhaling it. A large majority of those infected do not have symptoms, which is known as latent tuberculosis. Ten percent of those with latent TB developed an active infection in their lifetime and about half of those with active TB will die from the disease. Symptoms may be mild the first few weeks or months of the disease, easily spreading to others due to how highly contagious it is. The farthest back scientists have discovered TB is 2400BC through the spinal fragments of ancient Egyptian mummies. It was also found in bone fragments in South American from 750BC. Records prior to the 19th century have described this disease which then was also called consumption, white plague, dread disease, or the king’s evil. The spread of TB reached a peak during the 19th century Industrial Revolution in Europe where it killed one out of every seven people infected (UK Essays, 2014). The disease eventually spread to the United States when a large number of people immigrated to America and cities became vastly......

...exacerbating or causing stress on local water resources in some less developed countries. Review and discuss the evidence.  1 billion people do not have access to safe drinking water and estimates suggest by 2025 two thirds of the world’s population will be living in ‘water stressed situations’ (Momsen, 2004). Drinking unsafe water is a reality for many people living in less developed countries and can lead to life threatening problems including cholera. 96% of all infant mortality occurs in less developed countries and most are connected to inadequate water supplies (McDonald and Kay, 1988). As water is a necessary part of life, issues to do with water resources are hotly debated. One issue debated is connected to Coca-Cola, which has received a lot of criticism lately with questions raised over its attitude towards water resources in less developed countries. This essay will review the statement “Coca Cola’s operations have been blamed for exacerbating or causing stress on local water resources in some less developed countries” and discuss whether Coca-Cola deserves the bad press it had received.             Images: (Business Week [www], Art [www], Weblo [www]) Coca-Cola, the world’s largest non-alcoholic beverage company, sells products in over 200 countries.

Wbs Work Breakdown

...single summer season of safe and healthy family fun in the water, including appropriate levels of water sanitation and safe levels of appropriate chemicals. Since the pool has already been constructed, this WBS concerns only pool maintenance. The resources required for this project are minimal and include $300 in common pool maintenance products available at home improvement and pool specialty retailers. This project requires labor equivalent to roughly three hours per week aggregated over a three-month period. Body This generic WBS was used to maintain the pool, and it was effective in organizing maintenance efforts and ensuring timely testing. A scheduling system was devised through the use of a disposable weekly checklist and countdown timer. This was marginally effective, as sometimes, workers did not strictly adhere to timetables despite the aforementioned tools. Project status reports describe the completeness of various recurring tasks and assign percent completion to these tasks. An informal status reporting system was used for pool maintenance and was effective, as workers were always informed as to whether previous work had been completed, and whether to proceed with their own assigned tasks in proper succession.

...Cholera essay Cholera is a disease caused by a prokaryotic organism called vibrio cholerae, this bacterium has flagellum as it is prokaryotic and contains no unit bound organelles. The bacterium is transmitted through excrement of faeces and if this comes into contact with drinking water, the bacteria can infect people. Bacteria can also spread to food, if people don't wash their hands thoroughly after using the toilet meaning it can be spread from person to person. The symptoms of cholera include; extreme diarrhoea (as much as a litre an hour), vomiting for hours on end, and may also lead to dehydration and electrolyte imbalance which could then cause death. This is because the cholera bacterium produces a toxin, which affects chloride ion exchange. The toxin causes the chloride ion protein channels in the plasma membranes of the small intestine epithelial cells to open; the chloride ions then move into the lumen of the small intestine, this build up of chloride ions lower the water potential in the lumen. Consequently water moves out of the blood, across the epithelial cells and into the lumen by osmosis, the increase of water secretion in the lumen results in a high amount of water being lost from the body, which is what causes the symptoms. Ways to prevent cholera spreading would be; proper sewage systems, treating water, hygiene such as washing hands after using toilet and preparing food, also covering food which may come into contact the......

...especially when it comes to whether or not humans and animals should be allowed different rights, or whether they are completely equal. This also includes whether or not all humans should be equal. Moreover another huge concern with ethics is when an unethical action might be considered the best choice; for example it is considered unethical to use animals to do research, but in some cases this might looked past. Depending upon the benefits of the research some might be slightly ok with using the animals. Often there is controversy over whether or not humans and animals should be held to an equal level, and even more whether or not animals can feel pain just as humans. Some just like Peter Singer who Francis Fukuyama discussed in his essay, seem to believe that animals should be held to a higher power and be considered more valuable than that of humans. Fukuyama quotes from Peter Singer in his article “Human Dignity”, “the need for animal rights, since animals can experience pain and suffering as well as humans, and the downgrading of the rights of infants and elderly people who lack certain key traits, like self-awareness, that would allow them to anticipate pain. The rights of certain animals in his view, deserve greater respect than those of certain human beings” (Fukuyama 190). Overall, Singer is saying that depending upon the mental ability of the human and depending upon the animal it may be in demand of much more reverence than the human. Of course, there are......

...June 3, 2012 Water… Is it natural? Water is one of the primary substances for life and life cannot exist without it. One must consistently add fresh water to the body in order to keep it hydrated and healthy because it plays a vital role in nearly every bodily function. In addition, water is essential for proper digestion, nutrient absorption, and chemical reactions. Is water natural? Imagine not being able to drink clean water as a result of pollution. Water pollution is a very critical environmental issue and is harmful to the health and life of both humans and animals. Humans around the world must become aware of the dangers and the role they play in the quality of the water around them and improve in the ways water pollution is treated. In this essay, one will ascertain a thorough understanding of some of the causes and some of the dangers of water pollution and ways to prevent it. Even though water is a vital part of human life, many of the causes of water pollution come from humans and their ignorance. To name a few, water pollution is caused by agricultural runoffs, leaking sewer lines, and accidental leaks and spills. Agricultural runoffs are the result of manmade products like pesticides, insecticides, or herbicides and other waste from a large area of land. These products are made to help crops during their growth process and prevent them from being eaten by insects. As a result, these chemicals are washed into waters through......
