Performance Evaluation of a Sewage Treatment Plant STP A Critical Review

Increase in population and urbanization has lead to water depletion and deterioration in water quality. Construction of Sewage Treatment Plants STP based on latest technologies in different parts of the country is necessary to reduce the problem of water pollution. The purpose of STP is to reduce the excessive contaminants from sewage and make the sewage reusable. Sewage treatment helps to reduce the pollution level of the water bodies and reduce the use of water by ensuring that treated water is used for irrigation and flushing toilets. Thus, the efficient working of the STP is utmost important. Anaerobic and aerobic biological processes are commonly used for wastewater treatment. The efficiency of individual units of STP determines the overall performance of the plant and quality of the final treated effluent in accordance with the prescribed governmental standards. This paper presents a critical review on the treatment of sewage by aerobic process and specifically by Activated Sludge Process ASP and its modifications. From the present paper it can be concluded that Sequencing Batch Reactor SBR technology is good in treating sewage. G. D. Mali | P. S. Saler | D. S.
