ABSTRACT:
Liquid effluent from a conventional septic tank is passed successively through a filter tank and a plurality of spaced ozonating tanks, at least one of which has an activated charcoal filter located intermediate its ends. The filtered liquid passes from the last ozonating tank into a reservoir, and finally through an overflow outlet to a surrounding leach field. Perforated diffusers in the lower ends of the ozonating tanks are connected to an ozone generator which intermittently supplies ozone gas to the diffusers. Excess ozone gas is piped from the upper ends of the ozonating tanks back to the septic tank to increase the effectiveness of the septic tank. Dimethyl sulfoxide is added to the septic tank to prevent sludge formation.
