An industry wants to locate a chemical plant in your city, they expect to generate 25,000 gal/hr of waste containing 800 mg/L of BOD wastes (reactive) and 15,000 mg/L of inert (non-reactive) materials. The industry wants to recycle 300 gal/min (containing 20 mg/L BOD and 400 mg/L of salts) of discharge (effluent) from the municipal wastewater treatment plant to dilute their waste to 6,000 mg/L of inerts prior to pre-treating the wastes on their own property. If the rate constant for the first order degradation of BOD5 to be 0.75/hr, how big must the reactor be to treat the BOD entering the reactor to 200 mg/L?

A waste stream is discharging into a river at a rate of 5 m3/s. Upstream of where the waste stream enters the river, the river has a streamflow of 100 m3/s with a nitrate concentration of 1 mg/L. Downstream of where the waste stream enters, the nitrate concentration has been measured to be 3 mg/L. What is the nitrate concentration in the waste stream? Assume no change in storage in the system.
1. Assuming that the President Street Municipal Wastewater Treatment Plant (MWTP) processes on average 10 Mgal d' of raw sewage, and that wastewater has a typical organic carbon loading of 175g CL'. How much oxygen (in moles) would be lowered in the Savannah River is all of this waste TOC was remineralized? If the Savannah River flow is approximately 2.3 x 10°L d' and the river water started with 7 mg/L O2, how much change in the DO could happen if we did not treat this waste? Is there enough oxygen in the river?
. A wastewater treatment plant treats industrial waste and discharges 5.0 x 10-6 M benzene (C6H6) at a flowrate of 8 m3 /s into a 1.0 x 109 m3 lake. The stream feeding the lake has a benzene concentration of 1.0 μg/L and a flowrate of 100 m3 /s. Benzene has a natural decay rate of 0.038day-1.a) What is the concentration of benzene in the downstream? What is the maximum contaminant limit (MCL) for benzene? Does the concentration you calculated meet the MCL set by the Safe Drinking Water Act?b) If the standard is exceeded, by how many μg/L of benzene in the wastewater effluent will the treatment plant need to reduce?
