Abstract
Apparatus 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 vortex type centrifugal pump as back pressure is provided to the collector. The collector is mis-matched relative to the impeller to increase the retention and mixing time of the air and waste in the collector.
