Abstract: A method for dispensing a sanitizing composition comprising a carrier fluid involves passing a carrier fluid under pressure through a nozzle and a chamber mounted to the nozzle. The chamber receives the carrier fluid from the nozzle and has an opening on an opposite side from the nozzle through which the carrier fluid exits the chamber. Ozone is provided to an interior of the chamber in the presence of the carrier fluid, and is irradiated with ultraviolet radiation as the carrier fluid and the ozone pass through an interior of the chamber.

Abstract: A system is proposed for cleaning and sterilization wherein a carrier fluid is provided through a spray head having a mixing chamber, the flow of carrier fluid converted to a spray by the spray head. In the mixing chamber, ozone and ozone reaction products are mixed with the flow of carrier fluid to obtain a higher mixture of ozone and ozone reaction products in the carrier fluid immediately before the carrier fluid and ozone and ozone reaction products are dispensed as a spray.

Abstract: A process for sanitizing and cleaning wherein water containing ozone and other substances is sprayed through a spray head. The spray head contains a mixing chamber wherein ozone and other chemicals are mixed prior to being sprayed. The spray head also imparts an electrostatic charge onto the water or cleaning solution prior to be emitted from the spray head. Ozone is drawn into the spray head from an ozone generator through a tube positioned near the mixing chamber. The ozone generator may further comprise orienting at least one port on both a first and a second Venturi in the interior of the ozone generator to enhance the process of ozone production. A halogen generator may be incorporated into the process to add a sanitizing halogen to the water or cleaning solution.

Air tubes (62a, 62b, 72) are connected to Venturi suction ports (30) or an external use (FIG. 7) and have openings (64) therealong are oriented very close to the ultraviolet lamps (14), with openings (64) facing the ultraviolet tubes (14) in order to draw ozonated air directly from near the surface of the ultraviolet lamps (14). Ultraviolet lamps (14) may be pulsed with high power pulses of a frequency and duration determined by an air flow rate through the air tubes (62a, 62b, 72) in order to maximize ozone production. An external Venturi suction port may also be provided.

Abstract: A combined ozone and ozonites generator and ozone eliminator is disclosed. The device uses different modes of operation to control generation or elimination of ozone, with some modes being used for generating ozonites, some of which are generally less reactive and provide more far reaching beneficial effects than ozone alone. The device uses 185 nm radiation to disassociate atomic oxygen leading to creation of ozone, and uses 254 nm radiation to disassociate ozone, reducing its concentration, with both processes leading to creation of ozonites. These effects are achieved by operating either lamp separately or by operating both lamps simultaneously while drawing air through a chamber containing the lamps.

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 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.

Abstract: Retrofit apparatus for retrofitting an ozone generator to a spa, hot tub or similar facility is disclosed. Here, a fitting is threaded into an air inlet of a spa or hot tub, and covers provided for the water outlets to generally prevent outgassing. In another embodiment, an ozone-providing plug is provided to one water outlet of a spa or hot tub, with the air and other outlets being blocked. In addition, different configurations of ozone generator are disclosed. Particularly, one type ozone generator includes an inverted U-shaped apparatus so that heat from the ozone generator induces a chimney effect so as to cause the ozonated air to rise through a chimney and then settle into a selected area. Another ozone generator creates a low rate of airflow by “ion wind” in order to propel ozonated air into a system of piping in the absence of water flowing therethrough.

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.
