Design an aerated grit chamber for a wastewater treatment plant with an average flowrate of 15,000 m3/d and a peak hourly flowrate of 40,000 m3/d. Determine the amount of air required and the pressure at the discharge of the blowers. Allow a 250-mm loss in the diffusers, and add the submergence plus 400-mmloss in piping and valves. Determine the power required. Use a blower efficiency of 70 percent. Determine the monthly power bill, assuming a motor efficiency of 90 percent and a power cost of $0.12/kWh.
