ABSTRACT:
The improved high pressure oxygen-saturated water treatment apparatus of the present invention functions to provide super-saturated oxygen treatment to waste water for purification thereof. The apparatus includes a pressurized treatment tank having a substantial longitudinal dimension, with a chamber separation plate forming two interconnected chambers in the tank. An input conduit for flowing waste water into the first chamber of the tank is provided. An oxygen input conduit is connected to the tank for providing oxygen-containing gas under substantial pressure within the tank. An oxygen output conduit is also disposed on the tank for receiving the oxygen-containing gas from the tank to form a pressurized oxygen-containing stream. A venturi is also disposed on the tank for receiving and combining the pressurized oxygen-containing stream with recirculated water from the tank to form a combined injection stream of pressurized water which is super-saturated with oxygen, and which is then injected into the treatment water contained within the tank. As the tank is maintained at a pressure lower than that of the injection stream, the pressurized oxygen comes out of solution in tiny bubbles preferentially about particles of solid waste to entrain and provide supplemental floatation thereto. The result is to substantially oxidize any oxidizable material contained within the tank. The treated water is then removed by suitable means from the tank from the second chamber thereof.
