ABSTRACT:
Dual purpose apparatus and process for increasing the efficiency of absorption of oxygen by a biodegradable waste in a continuous operation in a waste collection station and for removing the oxygen enriched waste from the collection station by separately introducing waste and oxygen, which may be air, into a collector under a highly agitated state, and agitating the air and waste under pressure in a collector by a partially recessed vortex type impeller as back pressure is provided to the collector either by a nozzle means or an outlet means. The collector is mis-matched relative to the impeller to increase the retention and mixing time of the air and waste in the collector. The oxygen enriched waste is removed from the collector either by the nozzle means into the waste water in which the apparatus may be immersed, or the outlet means, wherein said outlet means also serves to remove the waste from the collection station, said nozzle means or said outlet means being alternatively actuated with regard to the passage of waste there through by a value diverting means.
