  • Patent number: 7892502
    Abstract: An improved system and method for controlling ozone concentration in connection with a multi-chamber tool. The system and method involve a first and a second concentration controller in combination with an ozone generator. The first concentration controller detects an EVENT (i.e., one of the chambers in the multi-chamber tool coming on-line or off-line) and in response provides a power instruction to the ozone generator in accordance with a predictive control algorithm. The first concentration controller has a fast (i.e, about 1 second) response time. The second concentration controller is masked from the ozone generator during the EVENT, but otherwise controls the generator after an interval of time has lapsed after the EVENT. The second concentration controller has a slower response time than the first concentration controller, however the second concentration controller provides the system with long-term stability and can be used to provide updated data to the predictive control algorithm.

Based on said electrostatically ionized oxygen containing gas ionized ozone gas is generated in an ozone generator; said ionized ozone gas is supplied to said sterilization chamber for attracting said ionized ozone gas to the surfaces of said at least one charged item; and said at least one item is exposed to the ionized ozone gas for a predetermined time period. Said apparatus and method provides for a rapid, safe and inexpensive sterilization.

  • Patent number: 7344685
    Abstract: A sealed multi-chambered bag, that is a flexible container, is made of dielectric material and contains two electrode plates (preferably screen plates) that are separated by an internal wall of the bag. Materials to be sterilized are placed between one or the other or both of the electrode plates and the interior wall. The interior wall allows the plates to be contained within the bag without the risk of damaging high voltage discharges occurring between plates optimal ozone production occurs in the bag immediately adjacent to where the materials to be sterilized are located. The bag is placed within a chamber containing an aperture which is connected to the intake of a pump. A conductor connects each electrode plate to an opposed terminal of a high tension transformer.

  • Patent number: 7314600
    Abstract: An apparatus and method for generating ozone is provided. An ozone generator comprises a substantially transparent element having ozone-generating means mounted on an inner element area and an outer element area. An enclosure is positioned over the element, and an oxygen-containing gas is directed through the inner element area, creating ozone from a portion of the oxygen-containing gas. The ozone and oxygen-containing gas is then redirected over the outer element area, so that the oxygen-containing gas is at least twice exposed to the ozone-generating means, thereby generating additional ozone.

  • Patent number: 7244354
    Abstract: This portable appliance can be used to clean teeth by liquid (water or solution) containing dissolved ozone, which is a potent oxidizer and germ killer. Preferably, its cleaning action is enhanced by pulsations of the liquid stream. The dissolved ozone can reduce or eliminate gingivitis, gum bleeding, bad breath, teeth stains, and harmful oral bacteria. This appliance can also be used for nasal irrigation for sinusitis treatment and for ear irrigation, eye care, and general cleaning. Additionally, since its output pump is independent of the ozone dissolving system, the ozone dissolving system can be configured as an add on device for an oral irrigator such as a Water Pikā„¢ manufactured by WaterPik Technologies, Inc. In this configuration, the ozonated liquid is delivered by either gravity or pumped flow, to the original reservoir connection with the irrigator serving as the delivery portion of this invention.

  • Patent number: 7186334
    Abstract: Water sanitizing apparatus is provided for pools, spas hot tubs and other similar bathing facilities that integrates an ozone generator and a chlorine generator in one unit, in addition to exposing a flow of water to be purified to ultraviolet radiation from the ozone generator for advanced oxidation reactions. In one embodiment, a mixing venturi allows for mixing various substances together prior to insertion into the motive flow. In another embodiment the venturi is constructed as inserts that allow tuning of the venturi for individual systems. In other embodiments, salt is added to a portion of the water flow as a concentrated brine from which chlorine is generated, or the salt may be simply be added to the water of the facility at a much lower concentration and chlorine generated from the flow of water through the apparatus.

  • Patent number: 7135108
    Abstract: A water purifying apparatus is constructed having a plurality of vertical, water-carrying tubes circumferentially arranged so as to form a hollow central region enclosed by the tubes. A top cap and bottom cap are configured so as to channel water through the tubes in serial relation and alternately in upward and downward directions. The hollow central region forms a last water-carrying chamber, and houses a bubble separator and ozone generator. A venturi mixes ozone at an inlet to the first water-carrying tube. The ozone generator is constructed having an ultraviolet-transmissive tube sealed from the water in the hollow central region, and contains an ultraviolet lamp that in addition to generating ozone, provides ultraviolet light to kill pathogens that survive the ozone treatment and also disassociates ozone. A closed loop system may be implemented by providing gas from the bubble separator back to the venturi.

  • Patent number: 6994831
    Abstract: The Oxidative Tritium Decontamination System, OTDS, provides a method and apparatus for reduction of tritium surface contamination on various items. The OTDS employs ozone gas as oxidizing agent to convert elemental tritium to tritium oxide. Tritium oxide vapor and excess ozone gas is purged from the OTDS, for discharge to atmosphere or transport to further process. An effluent stream is subjected to a catalytic process for the decomposition of excess ozone to diatomic oxygen. One of two configurations of the OTDS is employed: dynamic apparatus equipped with agitation mechanism and large volumetric capacity for decontamination of light items, or static apparatus equipped with pressurization and evacuation capability for decontamination of heavier, delicate, and/or valuable items.

  • Patent number: 6967009
    Abstract: An ozone generator is proposed which comprises a plurality of plate-like ozone generating elements, stacked one on top of the other, which are in at least partial contact with a process water stream, each of the ozone generating elements having at least one plate-like, electrically insulated inner electrode and at least one likewise plate-like counterelectrode, between which a space is provided for a gas discharge. According to the invention, the ozone generating elements are situated at a distance from one another, perpendicular to their plate-like extension, in such a way that process water is able to flow between the ozone generating elements over substantial surface regions of the plate-like ozone generating elements.

  • Patent number: 6967008
    Abstract: An ozone generator that serves the double functions of providing a light source and providing ozone is disclosed. Particularly, the ozone generator may be located in a generally closed appliance, such as a refrigerator, dishwasher, clothes washer or drier or the like. In addition, a stand-alone embodiment is disclosed that may simply be mounted or placed in storage or other areas such as closets, pantries, laundry rooms, clothes hampers, bed linen storage trunks and others. In some embodiments, timers are used to periodically raise ozone levels to relatively high levels and then allow the levels to fall, sanitizing and deodorizing the areas within which they are located. In other embodiments, advanced oxidation techniques are used by using a pair of ultraviolet tubes, one emitting radiation at a wavelength of 185 nm and the other emitting radiation at 254 nm.

  • Patent number: 6951633
    Abstract: An ozone generator utilizing an ultraviolet light tube for generating ozone is disclosed. In this ozone generator, efficiency in converting oxygen to ozone is increased by imposing an electrical field around the light tube. This electrical field causes a theta pinch in the plasma of the light tube, increasing luminescence in the ultraviolet spectral range and exciting diatomic oxygen molecules passing through the electrical field. Thus excited, the diatomic oxygen is easier to disassociate and become converted to ozone.
