Uniform oxygen dispersion Complete basin circulation.

The Aire-O2® Aspirator Aerator produces a horizontal and circular flow pattern, providing whole basin circulation. Improve your wastewater treatment with higher removal rates of Biochemical Oxygen Demand (BOD) and suspended solids.

The surface aspirator aerator offers a rotating propeller that forces water outward horizontally past the end of the shaft at high velocity. This creates a vacuum drawing air down the shaft into the water. Above the water line, atmospheric air is drawn through intake ports and travels through the hollow drive shaft to be dispersed in a large plume throughout the water. Being diffused into fine bubbles, about 2.0 mm in diameter, the oxygen has extended contact time with the water. The size of the plume varies with the size of the aspirator aerator which can be from 2 to 100 hp. Properly positioned, the Aire-O2 Aspirator Aerator units can create a “flow linkage” that delivers mixing and oxygen dispersion evenly and thoroughly throughout an entire basin regardless of its size or shape. Dead spots are eliminated.
