ABSTRACT:
An improved aeration device for septic tanks which allows fine bubbles of air to aerate waste material in the tank so that aerobic bacteria may fully perform their decomposing function. Air enters the upper end of a shaft and exists adjacent a propeller. The propeller is protected from interfering with its bubble formation action by a guard bushing concentrically positioned in the air tube so that typical non-organic waste adulterants such is plastic and rubber materials, that are often found in septic tanks, are not drawn into the propeller to interfere with its action.
