Abstract
In the treatment of wastewater by the activated sludge process, mixed liquor in the aeration tank or settled sludge is drawn from the system and concentrated. The concentrated sludge is returned to the aeration tank either immediately or after being mixed with separated water and settled sludge to thereby reduce the SVI of the mixed liquor in the aeration tank.
