Patent ID: 8425857

Claim:
A system for ozone sterilization of waste material, comprising: a tank including a top surface, a bottom surface and a substantially cylindrical side wall that define a substantially hollow chamber configured to receive waste material, ozonated water, and ozone gas, wherein the tank includes a first inlet to receive the waste material, a second inlet to receive ozonated water and ozone gas, a third inlet to receive the re-circulated slurry, and an outlet to discharge the slurry to the pump, wherein the first, second and third inlets are positioned within the substantially cylindrical side wall and the outlet is positioned within the bottom surface; an ozone system to generate the ozonated water and coupled to the second inlet; a pump coupled to the tank to receive the waste material and the ozonated water from the tank and form a slurry, the pump comprising a cutter assembly to reduce a particle size of the slurry through cutting; a circulation loop coupled between the tank and the pump to receive the slurry from the pump and re-circulate the slurry to the tank until the slurry is sterilized; and a deflector plate positioned on the bottom surface of the tank at an angle and height to allow recirculation and deflection to guide the slurry from the third inlet to the outlet after re-circulation, wherein the third inlet is positioned behind the deflector plate with respect to the outlet at a height and position to allow recirculation for the circumference of the tank wall.
