A 500-gallon tank originally contains 100 gallons of fresh water. Beginning at time t = 0, water containing industrial waste is pumped into the tank at the rate of 2 gal/min, and the well-stirred mixture leaves at the rate of 1 gal/min. Find the concentration of industrial waste in the tank at the moment it overflows. Use Integrating Factors
A wastewater treatment plant discharges 20,000 m3/d of treated sewage into a river. The effluent’s BOD is 25.0 mg/L. The river’s flow and velocity are 5,500 m3/d and 23 km/hr, respectively. At the point of the effluent discharge, the river’s BOD and DO are 2 mg/L and 6 mg/L, respectively. The river’s water temperature is 25 °C. The deoxygenation coefficient, kd, was determined to be 0.45 day-1, and the reaeration coefficient, kr, is 0.52 day-1. Apply the plug flow model assumptions and calculate the the oxygen deficit at the point of the effluent discharge, the BOD at the point of the effluent discharge, the critical time and distance and minimum DO level.
