Abstract: The present experiment deals with the use of secondary treated sewage by Up flow Anaerobic Sludge Blanket (UASB) followed by algal pond for tertiary treatment of secondary treated effluent along with aquaculture practices. Water quality is an important parameter which governs fish growth. Water quality standards vary significantly due to different environmental conditions, ecosystem and intended human uses. This experiment was carried out during February to April months with algal pond water as culture medium. The water coming from UASB reactor is directly discharged into algal pond water for tertiary treatment along with aquaculture. The growth of tilapia (Oreochromis niloticus) fishes was observed and treatment efficiency was measured in terms of organic waste as well as pathogens removal. The results obtained from the experiment shows 80.10±2.4% of total nitrogen removal with influent total nitrogen concentrations of 20±3 mg/L. Phosphate removal after treatment in algal tank was 90±1%. There was 2-3 log scale pathogen removal was also observed after treatment in algal tank. The maintenance of good water quality is essential for both survival and optimum growth of culture organisms. In conclusion, apart from wastewater treatment UASB-Algal-tilapia ponds also offer marketable by-products as fish protein including algal biomass, which correspond to cost recovery for sewage treatment.
