Effluent quality of the treated wastewater is an important parameter for its reuse. Comprehensive data on the raw and treated effluent of domestic, medical, industrial effluent characteristic are not available in Jamshedpur city, therefore a comparative study of the existing treatment plants in the city was carried out to access the effluent quality for present and future reuse. The study further evaluates the water of 6 STPs in Jamshedpur and 1 STP in Puri. For the reuse of the treated wastewater four parameters are necessary to check i.e. BOD, COD, TSS, pH which was carried out in the study. These STPs are based on the Activated Sludge Process (ASP), Anaerobic treatment (UASBR), BIOFORE, MBBR. STPs employing MBBR and UASBR technology showed the better removal of COD, BOD, and TSS removal as compared to other treatment process based on STPs. There could be improvisation in the current wastewater treatment for better treatment so; a proposed treatment scheme is designed for wastewater treatment plant after the study of different treatment plants. Based upon the physical, chemical, and microbiological removal efficiencies, the actual integrated efficiency of each STP was calculated (IEa) to evaluate its suitability for reuse in irrigation, gardening, and industrial purpose. Two biggest plants of Jamshedpur “kharkai” and “bara” required modification in the treatment process for better reuse of the effluent. Possible reuse option in Jamshedpur and Puri depending on the geographical location has been investigated which include gardening, automobile washing, boiler feed, cooling towers, irrigation, etc. All the experiments were done in Bara laboratory and some necessary data were taken from JUSCO Ltd (Jamshedpur).
