An aerated lagoon wastewater treatment is to be designed for a municipal wastewater. The design population is 5000 persons, and the aerated lagoon is to provide secondary treatment. Pertinent data are: flow = 380 L/cap-d, influent BOD5 = 255 mg/L; effluent BOD5 = 20 mg/L, K = 2.18 d-1 oxygen required 1.6 kg O2/kg BOD5 applied to the lagoons, and the primary clarifier removes 33 % of the influent BOD5. Calculate the total lagoon volume (m3)
