  • Patent number: 9272924
    Abstract: A process and apparatus to remove and breakdown volatile organic compounds from drinking water, groundwater, wastewater, frack water and air exhaust. The process entails filling a tank, chamber, pipe, or column with ozone-containing gas, introducing into this ozone-containing gas-filled tank, chamber, pipe or column, very small droplets of water, contaminated with volatile organic compounds which then volatilize out from the water and break down in the ozone gas thereby improving the water quality and associated air quality. The current invention has been shown to achieve more than 99% combined removal efficiency. The process can also be used to treat air streams containing volatile organic compounds. To increase efficiency, ozone is introduced where the atomized particles are smallest. Three configurations utilizing said process include upward and downward spray of contaminated water into ozone and pumping through openings in an enclosure to a reaction chamber filled with ozone-containing gas.

    Abstract: Systems, apparatus and methods are described that control and manage wastewater collection and treatment. One or more sensors monitor and measure levels of contaminants, other chemicals and or environmental conditions in a well of a collection station and/or in inflow and/or outflow mains. An additive that can include one or more of ozone, oxygen, a bioagent, bleach, peroxide and other chemicals, and selected to treat chemicals and/or contaminants in wastewater, can be mixed with waste water in the well and the main. A dispersion assembly deployed within the collection station is adapted to mix and spray the waste water and additive onto a wall of the well or surface of a body of wastewater in the well. A processor configured to control the rate at which the additive is provided to the dispersion assembly or force main based on measurements of contaminants received from the first and second sensors.

  • Patent number: 8980105
    Abstract: A portable, personal advanced-oxidation water treatment system based on ozone and a catalyst such as titanium dioxide that can cycle and purify water to make it portable by removing organic contaminants. The unit can be used for long periods of time without having to replenish the active portions. The unit can be carried in a backpack or in a vehicle. Fresh water is typically loaded into the unit, and the unit is cycled until the water is pure enough to drink. A battery is used to produce ozone and to cycle the water through a reaction vessel and can optionally be charged with a small solar panel The unit can also be powered directly from a vehicle.

  • Patent number: 8968569
    Abstract: A method of wastewater reutilization by which reusable water can be stably obtained from a wastewater. Ozone is added to a wastewater, such as water resulting from sewage treatment, in such a small amount as to result in a residual ozone concentration as measured before membrane filtration of 0.01-1.0 mg/L. Ozone is thus brought into contact with fine solids contained in the wastewater to alter the surface properties of the fine solids so that the solids are easily to coagulate. Thereafter, a coagulant, e.g., PACl, is added from a coagulant addition device (3). The fine solids are coagulated in a coagulation tank (5) or a line mixer and the resultant water is subjected to membrane filtration with an ozone-resistant separation membrane (6) such as ceramic membrane. Thus, reusable water is obtained which has a residual ozone concentration, as measured after filtration through the membrane, less than 0.5 mg/L.

  • Patent number: 8926842
    Abstract: A water treatment system using a high pressure advanced oxidation process with unreacted ozone reusing is disclosed, which are able to increase a decomposition speed of a pollutant by reusing a high pressure advanced oxidation process which uses an ozone and photocatalyst and a photo-oxidation reaction of a ultraviolet ray. The capacity of the expensive ozone generator can be reduced as compared to the conventional advanced oxidation process which uses a large capacity ozone generator in which almost ozone is discharged into the air. In addition, it is possible to decrease the load of the off-gas ozone removing apparatus for removing the off-gas ozone which is discharged into the air.
