ABSTRACT:
An improved method for aerating and mixing waste water which is circulated through a plurality of passages in submerged mixing chambers from an inlet to outlet of each wherein gas is mixed with the water, preferably by forming two parallel streams. To flush debris from the mixing chambers and conduits: (1) each inlet is connected to a location higher than the inlet, and at a lower pressure; (2) circulation of water is stopped; and (3) gas is continued to be forced into the passages to create backward flow of waste water through each chamber from outlet to inlet and thence to the higher location, carrying lodged debris out of the chambers and conduits. Intermittent gas flow creates pulsations which help dislodge debris.
