2. A complete mixed activated sludge process is being designed to treat 11,000m3/day of municipal wastewater. The wast water contains organic material with an ultimate BOD of 150mg/h that must be reduced to 15mg/L before discharge to a receiving stream. The following dosign parameters have been obtained from a pilot plant analysis: - Second-order rate coefficient =0.05L/mg-bacteria-day - Yield coefticient =0.2g bacteria /g BOD - Bacterial biomass concentration =2000mg bacteriar Determine: a) The aeration tank volume. b) The total mass of BOD removed each day from the aeration tank (in kg/day)
