VARI-CANT® Jet Aeration Systems

VARI-CANT® jet aeration systems utilize proven principles of jet aeration, combined with state-of-the-art design and materials, resulting in a system with superior performance, efficiency and trouble-free operation.

The VARI-CANT® jet aeration system intermixes air with a motive liquid and injects the stream into the wastewater. The aerator itself consists of two jet nozzles. The motive liquid - recirculated mixed liquor is discharged from an inner nozzle into an outer mixing nozzle . Compressed atmospheric air is introduced, and sheared into tiny bubbles which are entrained in the motive liquid stream. As the stream is discharged into the surrounding mixed liquor, it forms a highly turbulent jet plume. The plume entrains the surrounding mixed liquor and brings it into contact with the tiny air bubbles, resulting in a extremely high oxygen transfer rate.
