  • Patent number: 5685980
    Abstract: A water purification unit including a water inlet having a filter adapted to remove undissolved contaminants from a raw water source. The water inlet is coupled to a water reservoir including a semi-permeable membrane adapted to remove dissolved contaminants from raw water source. The filter and the membrane function to produce permeate water having undissolved and dissolved contaminants removed therefrom. The unit further includes a pressure source positioned within the water reservoir, wherein the pressure source forces raw water through the semi-permeable membrane. In addition, the unit is provided with a purified water container in fluid communication with the water reservoir adapted to receive the permeate water, wherein the purified water container is coupled to an oxidizing agent source. The oxidizing agent from the oxidizing agent source contacts the permeate water to destroy any contaminants that still may remain in the water.

  • Patent number: 5656246
    Abstract: A system for enhanced contaminant destruction through the use of oxidation processing. The system includes a contacting process chamber where ozone is solubilized into a solvent to create ozonated solvent and an oxidation processing chamber coupled to the contacting process chamber which selectively supplies ozonated solvent to the oxidation processing chamber. The system further includes an ozone generator coupled to the contacting process chamber and the oxidation processing chamber to selectively supply ozone to either chamber. A gas treatment system is coupled to the contacting process chamber and the oxidation processing chamber to treat gases produced in the contacting process chamber and the oxidation processing chamber for destruction or reuse, wherein the gas treatment system is selectively in fluid communication with the contacting process chamber and the oxidation processing chamber.
