Abstract:

A system for treating a fluid in a container. The system includes an included airlift tube and active air input into the tube. The air is supplied by a pump that is external to the tank and sized in accordance with the size of the tank. The system is arranged to promote the generation of suspended growth bacteria. The bacteria are provided by an air supply that is diffused in the tube wherein the air carries naturally occurring bacterial spores. The airlift tube includes one or more inlet ports located below an air diffuser. The tube may be located on the floor of the tank, suspended from the ceiling of the tank or arranged to float within the tank. A plurality of tubes may be used together to treat fluids in containers larger than standard septic tanks. A pH neutralizing device may form part of the system.
