An activated sludge process plant of 90% efficiency is designed for a city of population 5,00,000 having maximum water demand of 180 l/c/d. Waste water remains in aeration tank for 12 hours whereas biomass remain in system for 8 days. If incoming BOD to ASP is 240 mg/lit and waste sludge per day is 8775 kg and effluent biomass is negligible then removed per kg of biomass per day. Assume 78% of water supplied is converted into waste kg of BOD is water.
