ABSTRACT:
A motor supported by a float drives an impeller having eight symmetrically oriented vertical vanes radially attached to a cylindrical hub submerged below the surface of a wastewater lagoon. The size, position, and rotation rate of the impeller are selected to centrifugally expel wastewater between the vanes and cause a vacuum therebetween. An air vortex is produced between the lagoon surface and the top of the impeller, drawing air along the shaft of the impeller into the vacuum region. The incoming air and water is "sheared" by the vanes, causing great turbulence producing a mixture of water with millions of minute air bubbles entrained which is centrifugally thrown outward by the impeller, producing a deep, large radius zone of influence. The minute bubbles remain in the wastewater for a relatively long period of time, greatly improving dissolved oxygen levels. An air screw device disposed in the air vortex region increases the efficiency of the device.
