A 4000-m³/day conventional activated sludge plant has an influent with a BOD5 of 190 mg/L and SS of 225 mg/L. What population would this plant serve? If the primary tanks remove 60% of the SS, what volume (m³) of primary sludge at 4% solids concentration must be removed from the primary tanks each day? Assume that the waste activated sludge is not returned to the primary tanks.

If the primary tanks remove 30% of the BOD5, what MLSS (80% volatile) should be maintained in the 3 aeration tanks, each 10 m * 10 m * 3.5 m, to provide an F/M ration of 0.3 per day.
