ABSTRACT:
An improved method and apparatus for aeration of septic tanks and the like. Because of the interrelationship of the rotating impeller, an air plate and the horsepower of the unit in comparison with the volumetric size of the sludge tank, the unit disperses extremely small reduced pressure microbubbles adjacent the area of the impeller. These reduced pressure microbubbles are thereafter dispersed throughout the wastewater by Brownian movement without agitating the sludge. As a result, there is substantially increased lateral oxygen transfer to replace the oxygen used by the aerobic bacteria. The sludge is therefore efficiently digested without the need for huge, expensive and energy inefficient equipment.
