Abstract

Septic systems incorporating an ozonation system comprise one or more corona discharge ozone generators receiving air, such as atmospheric air, and having an outlet for the withdrawal of a mixture of air and ozone gas. The system also comprises a septic tank for receiving primary wastewater, and a pump tank receiving secondary wastewater effluent from the septic tank. The ozonation system includes a submersible ozone introduction pump disposed in the bottom of the pump tank, wherein the ozone introduction pump includes an impeller within a housing, the housing having an inlet and a plurality of radial outlet ports along its circumferential area surrounding the impeller. A conduit couples the outlet of the corona discharge ozone generator to the inlet of the impeller housing, wherein the ozone introduction pump reduces pressure in the conduit to draw air into the ozone generator and draws the mixture of air and ozone gas into the impeller housing for introduction into the secondary wastewater. An optional ultraviolet light source may be disposed in the headspace of the pump tank to enhance the activity of the ozone.
