CENTRIFUGAL OXYGENATOR FOR TREATMENT OF WASTE WATER AND SYSTEM

摘要

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 (17) under a highly agitated state, and agitating the air and waste under pressure in the collector (17), by the impeller (21) of a centrifugal pump, as back pressure is provided in the collector (17). The collector (17) is mismatched relative to the impeller (21) to increase the retention and mixing time of the air and waste in the collector (17). The collector (17) with the impeller forms a pump designed to operate close to its shut-off condition for increased retention time in the collector (17).
