Abstract
A system and method of aerobic wastewater treatment provides large mixing bubbles along with small oxygenating bubbles supplied by diffusers. The mixing bubbles are large enough to move wastewater and generate a mixing current as they rise to the surface. The mixing current mixes the wastewater, bacteria and other microorganisms, and the small oxygenating bubbles from the diffusers to promote the bacteria and other microorganisms' conversion of the pollutants contained in the wastewater. The mixing provided by the large mixing bubbles enhances the efficiency of wastewater aeration provided by the small oxygenating bubbles.
