    Determine the minimum dissolved oxygen (DO) concentration in a river downstream from a wastewater treatment plant (WWTP) discharging at a flow rate of 5.00 million gallons per day (MGD). The WWTP achieves secondary treatment standards (BOD5 = 30 mg/L). The wastewater temperature is 25.0 °C and contains 4.0 mg/L of DO. The characteristics of the river upstream from the point of discharge are Q=20.0 cubic feet per second (cfs), T = 20.0°C, BODu = 3.0 mg/L. and DO = 7.0...

    NT4-1. 3 pts. A beef stick manufacturing plant proposed to discharge saline (salty) wastewater to a river. Upon reviewing the proposal, the governing regulatory agency set a 200 mg/L salt maximum level in the river downstream of the discharge point. In response the manufacturing plant proposed adding desalination equipment between the manufacturing plant and the river to remove enough salt from the wastewater to meet the regulatory requirement, 15% of the wastewater flow becomes brine (concentrated salt), a byproduct from...

    1. In 1970, the total phosphorus (TP) load to Lake Erie was 18.150 tonnes/year (where tonnes or metric ton = 1,000 kg). The surface area, volume, and outflow from Lake Erie are given as 25.2 x 10 m² 468 x 10 m, and 182 x 10 m yr, respectively. Based on previous evaluations, the total phosphorus is removed from the lake with an apparent settling rate of 16 m/yr. a. Draw a diagram and write the mass balance equation for...
