Question

Lake Mustang has a surface area of 4100 m² and an average depth of 15 m. The
lake is fed by a stream with a flow rate of 2.02 m³/s and a phosphorus
concentration of 0.023 mg/L. The campus wastewater treatment plant
discharges into the lake at a rate of 0.2 m³/s and a phosphorus concentration of
1.1 mg/L. Runoff from the dorm areas adds phosphorus at an average annual
rate of 1.35 g/s. A river flows from the lake at a flow rate of 2.42 m³/s. The
average steady-state phosphorus concentration in the lake is 0.380 mg/L.
Assume evaporation and precipitation balance each other out over the year.
What is the settling rate in the lake (d-¹)?

A lagoon with a volume of 1200 m3 has been receiving a steady flow Q = 100 m3/day of a non-conservative pollutant with a reaction rate constant k1 = 0.2 day-1 for a long enough time to assume that steady state conditions apply (there is an effluent stream flowing out that needs to satisfy steady state conditions). The waste entering the lagoon has a concentration of 10 mg/L.Assuming complete mixing conditions, what would the concentration of the pollutant be in the effluent leaving the lagoon?
The town of Viracocha discharges 17,360 m³/day of treated wastewater into the Pachacamac Creek. The treated wastewater has a BOD5 of 12 mg/L and a BOD decay constant, k, of 0.12/day at 10 °C. Pachacamac Creek has a flow rate of 0.43 m³/s and an ultimate BOD, Lo, of 5 mg/L. The DO of the river is 6.5 mg/L and the DO of the wastewater is 1.0 mg/L. Compute the DO and the initial ultimate BOD, Lo, after mixing. Draw the Mass Balance Diagram.
