A flow of 2.6 MGD leaves a primary clarifier with a BOD of 131 mg/L. Determine the aeration period (hydraulic detention time) of an activated sludge tank that has a BOD loading of 35 lbsper 1000 ft3per day. Determine the sludge age of the facility given the following data: VSS concentration is 2100 mg/L, and the mass rate of wasted sludge is equal to 44 percent of the BOD loading.
