Patent ID: 7425269

Claim:
A method of aeration of industrial waster water to enhance biodegradation, comprising: moving atmospheric air downwardly through a confined elongated zone through use of a rotating louvered disc within said zone, said downward movement being into a larger zone of reduced air pressure and being through said louvered disc; whereby the downwardly moving air in said elongated zone interfaces the waste water in the area around the louvered disc, forcing water within the openings of the louvered disc to create agitation causing entrained air within bubbles smaller than 100 microns in diameter to disperse throughout the waste water, said bubbles being capable of staying entrained within the waste water for a time of from about 2 to about 6 hours; and maintaining the dispersed bubbles in said waste water to increase lateral oxygen transfer to replace dissolved oxygen used by aerobic bacteria present in the waste water.
