A city discharge 1600 lit/sec of sewage into a stream whose minimum rate of flow is 6000 lit/sec. The temperature of sewage as well as water is 20°C. The 5 day BOD at 20°C for Sewage is 200 mg/lit and that of river water is 1 mg/lit. The DO content of sewage is zero and that of the stream is 90% of the saturation DO. If the minimum DO to be maintained in the stream is 4.5 mg/lit, find out degree of sewage treatment required. Assume the de-oxygenation coefficient as 0.1 and re-oxygenation coefficient as 0.3,
