Find volume of the aeration basin in gallons to meet ratio

Reference no: EM13313425

A wastewater treatment plant has a flow of 30 mgd. The influent BOD is 250 mg/L. Assume that 30% of the BOD is removed in the primary clarifiers. The plant is designed to carry 3,000 mg/L of VSS in the aeration basin.

A. Find the volume of the aeration basin in gallons to meet a F/M ratio of 0.25 lb BOD per lb of VSS per day (= 0.25 d-1).

B. What is the wasteage rate in lb/d to meet a mean cell residence time
