Abstract
Apparatus and system for increasing the efficiency of absorption of oxygen by biodegradable waste and particle break-up thereof, by introducing waste and gas, which may be air, into a collector under a highly agitated state, and agitating the air and waste under pressure in the collector by the impeller of a centrifugal pump as back pressure is provided in the collector. The collector is mismatched relative to the impeller to increase the retention and mixing time of the air and waste in the collector. The collector within the impeller forms a pump designed to operate close to its shut-off condition for increased retention time in the collector.
