Question

The BOD of a river just below a sewage outfall is 40 mg/L. At this point, the DO is at the saturated value of 9.8 mg/L. The deoxygenation rate coefficient is 0.22/day, and the reaeration rate coefficient is 0.9/day. The river is flowing at 10 miles/day. There are no other sources of BOD in the river. A. Find the critical distance downstream at which DO is at a minimum. B. Find the minimum DO.

A lagoon with volume 1,300 m3 has been receiving a steady flow of a non-conservative waste (rate constant= 0.19/day) at a rate of 80 m3/day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 12 mg/L. A. What would be the concentration of pollutant in the effluent leaving the lagoon? B. If the input waste concentration suddenly increased to 110 mg/L, what would the concentration in the effluent be 8 days later?
