A modification of the conventional activated sludge process that uses 2 aeration tanks. One tank is for separate reaeration of the return sludge for at least 4 hours before it is permitted to flow into the other aeration tank to be mixed with the primary effluent requiring treatment. The process may also occur in a single long tank.
