  • Apparatus for aeration without significant agitation to deplete and biodegrade sludge
    Patent number: 6884353
    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.
    Type: Grant
    Filed: August 6, 2002
    Date of Patent: April 26, 2005
    Assignee: Sewage Aeration Systems, Inc.

  • Method for vacuum aeration of septic tanks to provide low pressure microbubbles
    Patent number: 6245237
    Abstract: An improved method for aeration of septic tanks and the like by drawing atmospheric air into an expansion chamber and from there into agitated sludge to provide low pressure small microbubbles which have long hold times in the sludge material.
