Surface Aerator

A Hubair™ surface aerator is designed for continuous operation

A surface aerator pushes water from under the water’s surface up into the air, then the droplets fall back into the water, mixing in oxygen. It is used to treat waste water –  it is effective in introducing oxygen to the top foot of a water volume. Surface aerators can also be used to keep still waters volumes circulating, healthy, and odor-free. 

Hubert delivers also floating surface aerators. When these have a high pumping rate, they can be very effective in water treatment lagoons, carousels and tanks.

Design & Construction

Our Hubair™ aerator consists of a flat sawtooth shaped plate fitted with twelve blades. The top of each blade has been reversed and bend oudwards at an upward angle of 350 degrees. This influences the direction of the water ejection.

This design has led to reduced friction losses, which not only means that the efficiency of oxygen input is improved but also that the axial stresses on bearings and gearbox are reduced.

The Hubair™ aerator’s standard version is manufactured from carbon steel finished with an epoxy coating. For aeration in higlhy aggressive environments a stainless steel aerator is available. The areator can be installed fixed (oxidation ditch and tank) or floating (tank or lagoon).
