Patent ID: 8652404

Claim:
A method for ozone sterilization of waste material, comprising the steps of: providing a tank including a top surface, a bottom surface and a substantially cylindrical side wall that define a substantially hollow chamber, wherein the tank includes a first inlet, a second inlet, a third inlet, and an outlet, wherein the first, second and third inlets are positioned within the substantially cylindrical side wall and the outlet is positioned within the bottom surface receiving the waste material in the tank via the first inlet; receiving ozonated liquid and ozone gas in the tank via the second inlet; mixing the waste material and the ozonated liquid within the tank to produce a slurry; pumping the slurry out of the tank via the outlet and into a pump; cutting the slurry into reduced sized particles in the pump; continuously re-circulating the slurry from the pump to the tank via the third inlet until the slurry is sterilized; guiding the slurry from the third inlet along the bottom surface of the tank to the outlet after re-circulation via a deflector plate positioned on the bottom surface of the tank at an angle and height to allow recirculation, and recirculating for the circumference of the tank wall via positioning of the third inlet behind the deflector plate with respect to the outlet at a predetermined height and position; and filtering the sterilized slurry.
