A wastewater plant discharges a treated effluent (w) with a flow rate of 1.1 m^3/s, 50 mg/L BOD5 and 2 mg/L DO into a river (s) with a flow rate of 8.7 m^3/s, 6 mg/L BOD5 and 8.3 mg/L DO. Both streams are at 20°C. After mixing, the river is 3 meters deep and flowing at a velocity of 0.50 m/s. DOsat for this river is 9.0 mg/L. The deoxygenation constant is kd = 0.20 d^-1 and The reaction rate constant k at 20 °C is 0.27 d^-1.
Required:
a. Find the initial DO deficit (Do) after mixing.
b. What is the reaeration constant after mixing?
c. What is the critical time for this system?
d. What is the downstream distance fitting the critical time?
