Homework SourseA wastewater treatment plant receives 50000 m 3 day of domes
A wastewater treatment plant receives 50,000 m 3 /day of domestic wastewater containing 220 mg/L of BOD and zero dissolved oxygen. Estimate the flow rate of air, in sdcm/day (“sdcm” is an abbreviation for “standard dry cubic meters”) required to be fed to a biological treatment process receiving the waste if the effluent contains 30 mg/L of BOD and 2.0 mg/L of oxygen.
