A high strength waste having an ultimate CBOD of 1,000 mg/L is discharged to a river at a rate of 2 m3 /s. The river has an ultimate CBOD of 10 mg/L and is flowing at a rate of 8 m3 /s. Assuming a reaction rate coefficient of 0.1/day, calculate the ultimate and 5-day CBOD of the waste at the point of discharge (0 km) and 20 km downstream. The river is flowing at a velocity of 10 km/day.
