This study examines the presence of pollution of river Yamuna in the city of Delhi. The condition of river Yamuna is deteriorating day by day. The main cause of this is the poor standard treated sewage from the sewage treatment plants being dumped into drains which directly meet into river Yamuna. In this study I audited Keshopur 40 MGD sewage treatment plant which works on activated sludge process in which Mixed Liquor Suspended Solids (MLSS) is the prime concern for the proper functioning of plant and checked the adequacy of the various functional units by comparing the detention time of each and every unit with the standard detention time given by code. Activated Sludge Process involves aeration and a biological flock composed of bacteria and protozoa to convert non settle particles into the settle one.ASP provides one of the highest degree of treatment within the limited cost involved. In this study various recommendations are also given for increasing the efficiency of sewage treatment plant.
