A wastewater treatment plant uses an activated sludge

A wastewater treatment plant uses an activated sludge process for secondary treatment of 0.300 cubic meters / second of primary effluent. The mixed liquor has a concentration of 2,100mg VSS/L, and the RAS concentration is 10,000mg VSS/L. The substrate concentration on the primary effluent is 220mg BOD5/L. THe F/M ration for the activated sludge tank is 0.52 mg BOD5 • mg VSS d(-1) • d(-1), and the cell residence time is 9.0d.

(a.) WHat is the volume of the activated sludge tank?

(b.) What is the WAS flow rate?

(c.) What is the flow rate of secondary treated effluent?

(d.) What is the hydraulic residence time for the activated sludge tank?
