Abstract
A wastewater treatment system: The system entails an aerobic tank and an anaerobic tank. Wastewater enters the aerobic tank where it is aerobically treated. The effluent then flows to the anaerobic tank where it is anaerobically treated to remove nitrogen in the wastewater. A filter may be added to the discharge line from the anaerobic tank to remove any suspended solids emitted with the effluent from the anaerobic tank.
