2. A manufacturing plant is discharging wastewater into a stream at a constant rate of 2.0 m²/sec. The concentration of a contaminant in the wastewater is given as 50 ppm. The average stream flow upstream of the discharge point is 6.0 m³/sec, and an upstream contaminant concentration of 4 ppm. The average depth of the stream is given as 1.5 m and the average width is given as 25 m. The contaminant is removed by a first-order reaction with a rate coefficient of 0.35 /day. Assume the stream behaves as a plug-flow system. a. Draw a diagram and write the appropriate (starting) mass balance equation(s).} See pdf Not sure how to proceed b. Calculate the concentration of the contaminant in the stream at the discharge point and at 25 km downstream.

You are building a wastewater lagoon with an inlet/outlet flow rate of 3,100 m3/day. The BOD inlet load is 26 mg/L and you need to achieve 12 mg/L at the outlet. The half-life of BOD is 2.4 days. What is the volume required for the lagoon? If the wastewater stopped entering the lagoon and was replaced by freshwater, how long would it take for the outlet BOD concentration to reach 1 ppm?
A company is trying to build a new plant in a location near to a stream. You been asked to find out the impact of the discharged wastewater from the proposed plant on that stream that has characteristics shown in the Table below. The expected plant effluent data is shown in the same Table.

A storm sewer is mixed into a small stream. The stream before the mixing point has a NaCi concentration of 25 mg/L. If the storm sewer has a Nacl concentration of 1.8 g/L and the storm sewer flowrate is 2.5 L/min, calculate for the concentration of the salt in the stream after the discharge point (mixing point). The stream has a flowrate of 2.6 cu.m/s. Assume a complete mixing of the storm sewer flow and the stream flow. Assume also that the salt is nonreactive and that the system is at steady state.
The flow rates measured during a precipitation at the outlet of a basin with an area of 32400 hectares are given below. It is assumed that the precipitation intensity is constant 60 mm/hr and the infiltration index of the basin is 10 mm/hr. Determine the duration of the unit hydrograph and obtain the 60-minute unit hydrograph of the basin. You can take the base flow as 100 m³/s.
