Abstract
A plurality of aerators are arranged in a preselected pattern on the floor of a basin or lagoon containing waste water. Compressed air is supplied to the aerators by aeration pipes anchored by hanger brackets to the floor of the basin. Each aerator has a porous diffuser plate through which the air is passed and released into the waste water in the form of ultra fine air bubbles less than 60 microns in diameters. The air bubbles are generated in an intense manner with a high rate of air flow to increase the mixing action and liquid circulation pattern, and to create turbulent boils at the surface which provide surface aeration from atmospheric air and re-entrainment of air from eddy current circulation.
