  • Patent number: 8871098
    Abstract: The invention discloses an apparatus and method to uniformly disperse ozone gas bubbles into liquid phase water for the treatment thereof. The apparatus consists of a water inlet section connected with a section with structured packing or monolith having parallel flow channels. A portion of the influent water is withdrawn from the main water stream as a side stream, pressurized by a pump, mixed with ozone-containing gas, and then injected back into the main water flow. The side stream may be divided into multiple streams either before or after mixing with the ozone-containing gas, and then injected into the main flow section upstream of the packed section. In alternate embodiments, the ozone-containing gas can be injected directly through the gas diffusers just upstream of the packed section in order to achieve uniform concentration of gas and liquid in the fluid entering the monolith.

  • Patent number: 8758618
    Abstract: The installation comprises three reaction vessels (100, 200, 300) in series, each containing an aqueous phase and a specific bacterial population. The vessels serve in succession to dissolve the liquid feedstock for treatment by enzymatic hydrolysis, then to biodegrade the resulting effluent by biological digestion, and finally to reduce the residual bacterial components by biological action. The vessels are mutually isolated by tangential filters (108, 208, 308) and by centrifugal separators (212, 312) for filtering the biomass from the reaction products. The result is a final liquid effluent (EFF/N) that is essentially non-organic, with the filtered biomass downstream constituting an ultimate organic waste (DU) of reduced volume.

    Abstract: The invention is a method for treating fluid in a main fluid reservoir, e.g., a pool, spa, or water tank, etc., using ozonated air. A fluid filter is placed in an auxiliary fluid reservoir located in or next to the main fluid reservoir. An ozone generator pumps a combination of ozone and air into the auxiliary reservoir. Fluid in the auxiliary reservoir passes through a filter and back into the main reservoir without the use of any fluid pump. More specifically, a vertical lift tube is placed beneath the auxiliary fluid reservoir so that the open top of the lift tube is within the auxiliary reservoir. Fluid from the main reservoir is fed to the bottom of the lift tube. Ozone and air from the ozone generator is also piped into the lift tube near its bottom. The fluid flows through the filter due to the effect of ozone and air bubbles released by a diffuser at the bottom of the lift tube.

  • Publication number: 20130161269
    Abstract: A method and apparatus of sanitizing drinking water to be dispensed from a water dispenser having a reservoir includes the steps of providing the ozone gas generator that generates an ozone gas stream, transmitting the ozone gas stream from the generator to the water dispenser reservoir, mechanically breaking up the ozone gas stream inside the reservoir to produce ozone gas bubbles, and using the ozone gas bubbles to disinfect water in the reservoir. The ozone gas stream can be mechanically broken up using a pump such as, for example, an impeller type pump.

  • Patent number: 8449777
    Abstract: A batch process for the treatment of an aqueous solution so that the treated product is more desirable for disposal includes obtaining an influent batch of aqueous solution for treatment, treating the batch of solution by an advanced oxidation process. The advanced oxidation process including causing ozone to be mixed with the solution, maintaining the mixture of solution and ozone at a pressure above atmospheric for a time of at least two seconds. In a preferred embodiment of the process, the process includes continuously recirculating the fluid to be treated, through a recirculation conduit, the recirculation conduit including an ozone injector and the ozone injector is adapted to inject ozone into the aqueous solution as the aqueous solution circulates through an ozone injector. Influent to be treated may be selected from the group including sewage, septage, leachate, ballast or other aqueous solutions where it is desirable to treat the fluid prior to disposal, further treatment, or reuse.

  • Patent number: 8440080
    Abstract: The present invention relates to a portable device for generating ozone in water, purifying the water and making it drinkable. The device comprises a housing; at least two electrodes, including an anode and a cathode extending from the housing into the water and each having semi-rough or rough surfaces in contact with the water. The device also comprises a power supply operatively connected to the electrodes for generating between them a difference of potential creating a current and the hydrolysis of the water creating ozone that purifies the water. The electrodes may have a plate or a rode and tube configuration with a plurality of holes with rough edges. The roughness of the surfaces and of the edges of the holes leads to a coalescence of tiny hydrogen bubbles into larger hydrogen bubbles. The hydrogen may be also removed by absorption in a conductive material and regenerated for reuse.

  • Patent number: 8425784
    Abstract: A method for increasing ozone concentration in a liquid can include: providing a gas having ozone; introducing the ozone-containing gas into a liquid, wherein the liquid and ozone combination has a temperature between about 0.8 and about 1.5 times the critical temperature of ozone; and increasing isothermally, the pressure of the ozone-containing gas above the liquid to about 0.3 to about 5 times the critical pressure of ozone so as to increase the ozone concentration in the liquid. The temperature is expressed in absolute units (Kelvin or Rankin). The method can be used for removing ozone from a gas or for purifying ozone. The liquid having a high ozone concentration can be used for ozonolysis of a substrate.

  • Publication number: 20130075345
    Abstract: The invention discloses an apparatus and method to uniformly disperse ozone gas bubbles into liquid phase water for the treatment thereof. The apparatus consists of a water inlet section connected with a section with structured packing or monolith having parallel flow channels. A portion of the influent water is withdrawn from the main water stream as a side stream, pressurized by a pump, mixed with ozone-containing gas, and then injected back into the main water flow. The side stream may be divided into multiple streams either before or after mixing with the ozone-containing gas, and then injected into the main flow section upstream of the packed section. In alternate embodiments, the ozone-containing gas can be injected directly through the gas diffusers just upstream of the packed section in order to achieve uniform concentration of gas and liquid in the fluid entering the monolith.
