engineering recuitment GATE CE 2023-24 Test Series Environmental Engineering Sewage Sewage Treatment
A trickling filter plant treats 1500 cum per day of sewage with a BOD5 of 220 mg/l and a suspended solid of 250 mg/l. Estimate the total solid production(in Kg/day) assuming that primary clarification removes 30% of BOD and 60% of influent solids. Take the solid production in the trickling filter as 0.5 kg/kg of the applied BOD.
