This project is a design of secondary treatment units for municipal wastewater treatment for a city. The population of the city is 250,000. Each person generates 300 L wastewater per day that contains 0.085 kg BOD5. The primary settling tank removes 15% of BOD. A conventional suspended activated sludge process is designed to remove the rest up to the discharge standard of 20 mg/L. 1. Characterization of wastewater. From the information about determine the characteristics of the wastewater: a) The daily flowrate b) The BOD5 of the raw wastewater c) The BOD5 after primary settling
