ABSTRACT:
An aerator apparatus for use in waste treatment plants and the like for imparting oxygen to the waste water forced through the apparatus by an axial flow impeller. The entire apparatus may be submerged, resting on the bottom of the body of water and has an intake area for directing water from the bottom of the body of water through the apparatus. The water is forced into a discharge chamber where it is aerated and agitated by a compressed oxidizing gas, such as air, through an array of ports surrounding the discharge chamber. From the discharge chamber the aerated water is directed out of the apparatus on a generally horizontal plane into the surrounding body of water. In one embodiment, the flow of water may be drawn from a certain direction and discharged in the same or opposite direction, as desired, to maintain a flow or current pattern in conjunction with a plurality of like aerators.
