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 & tanks.
