Abstract
Apparatus and a process for use in aeration of a fluid. The apparatus includes a tubular drive shaft having a first end and a second end. The first end is coupled to a selectively rotatable power source. A compressed air source is in fluid communication with the tubular drive shaft. A first propeller having a propeller shaft is coupled to the second end of the tubular drive shaft. An atomizing mechanism is located proximate the propeller shaft. The apparatus may further include a second propeller having a propeller shaft positioned between the first propeller and the second end of the tubular drive shaft. In another mode of operation, the aerator may be used solely as a mixer in an nitrification/de-nitrification process without the introduction of outside air or compressed air.
