Using the assumptions given in Example 8-4 (page 495), the rule-of-thumb values for growth constants, and the further assumption that the influent BOD_5was reduced by 32.0 percent in the primary tank, estimate the liquid volume of a completely mixed activated sludge aeration tank required to treat the wastewater in Problem 8-1 (above). Assume an MLVSS of 2,000 mg/L.
