Sewage treatment plants protect both public health & environment
The water that has been released from domestic residences, industries, commercial possessions, agriculture is highly pollutant and contains huge amounts of contaminants and concentrations. This wastewater can play havoc to the environment if left untreated. Sewage treatment plants are large facilities that treat tons of waste emanated from large industries, mills and factories. Sewage treatment plants are basically large facilities that are used to treat wastewater which includes big amounts of contaminants. This waste water is very harmful and if it is released in the surrounding areas it can lead to countless diseases. Separating solid waste from waste water is still possible but removing chemical and biological contaminants from the waste is not easy. Sewage treatment plants are used to purify waste water.
The process involved in a sewage treatment plant involves the cleaning up of sewage which is emitted from domestic and commercial sources. A waste water treatment plants company involves different stages in purifying the waste water such as physical, chemical and biological processes. The physical process of wastewater incorporates sedimentation, aeration and filtration. Sedimentation is the first step which involves deposition of solid waste in order that only liquid matter floats on the top. Subsequently the liquid matter is separated from the solid waste. Under the next- aeration process oxygen content is increased by mixing the waste with oxygen generated in aeration tanks. The third and the last process of sewage treatment plant is disinfection wherein the sewage is disinfected by removing toxicity so that it turns out to be fit and ready to be disposed in local water reservoirs.
As the name suggests, the chemical treatment of wastewater involves the usage of chemicals to remove the contaminants. Chlorination is one the most often used chemical treatment. However, oxidation is another type of famous chemical treatment wherein oxidizing agents such as ozone are used to treat impure and infected water. Bacteria and various other microorganisms are used in biologically treatment so as to decompose wastewater biochemical and also to stabilize it. Aerobic and Anaerobic are two categories involved in biological treatment. With the presence of oxygen in aerobic process the bacteria eats the organic matter and transformed it to carbon dioxide. However, there is no oxygen in the aerobic process and hence the sludge is fermented at specific temperature. Treatment plants also perform an important function of dealing with sludge that is left over from cleaning the wastewater.
It is very important to treat the waste water because if it is released directly to the environment, it will start stinking and turn out to be a breeding ground for harmful bacteria. Also, if human excreta which contains coliform bacteria mixes with bacteria in natural environment, it can become a serious health hazard. Wastewater contains solids and harmful chemicals such as nitrogen, bacteria and phosphates which can contaminate the environment badly.
