Abstract: An aeration system may have a submersible aerator that may be located on the bottom of a body of water and a floating aerator that may operate directly above the submersible aerator. The submersible aerator may create a laminar column of bubbles and may be powered by an air compressor. The floating aerator may use a motor driven propeller to agitate water on the water surface. A controller may determine when to operate the aerators, and may operate them separately or together in some instances. Some embodiments may have a controller that operates the aerators differently based on energy supply, which may vary in solar powered systems with a battery bank.

Abstract: Disclosed is a system and method for treating domestic and industrial biological waste using diffusers to force circulation and aerate a treatment lagoon. Several lagoons may be used in series to treat raw waste and different variations may be employed to stepwise process the waste. A blend of aerobic and anaerobic microbes is chosen to remove undesired species initially present in the waste or later formed therein, as well as to process the waste itself, depending on the nature of the waste. Aeration with slightly ozonated or oxygenated air facilitates rapid and complete processing of large amounts of waste.
