Abstract :
Wastewater is the by-product of municipal, agricultural and industrial activities. Removal of organic matter is essential to treat the water and meet the acceptable quality standards in order to prevent from water pollution. The purpose of this paper is to summarize the research work on study of effectiveness of Activated Sludge Process (ASP) at laboratory scale basis to remove the organic matters. ASP is the biological aerobic wastewater treatment that uses microorganisms to biologically oxidize the organic pollutants. This method uses naturally occurring bacteria and protozoa, thus it is eco- friendly as well as economical. From the experimental observation, it was found that about 52% of the BOD has been reduced through secondary treatment process, chlorides content reduced about 70%, acidity of water is reduced to 12 mg/L and DO of water is 12. The treated water can be discharged into stream or used in construction activities. Based on the performance of ASP in treating domestic effluent, this can be found as cost effective, effectiveness, good quality in effluent treatment, efficient removal of BOD and COD.
