The CH Surface Aerator consists of a turbine-type aerator, which is mounted just below the surface of the liquid to be aerated. The action of the turbine creates a vortex, lifting large quantities of oxygen-deficient liquid from the bottom of the basin, pumping it through the oxygenation zone, discharging it radially, and dispersing it throughout the liquid body at a low velocity. Every unit of the surface aerator's impeller will be given a dynamic balancing correction to maximize the service life of the gearbox.
