Patent number: 8161579Abstract: A self contained battery energized apparatus is mounted within the water tank of a conventional flush toilet to eliminate malodorous gases. Air from the toilet bowl is drawn through the stand pipe in the toilet tank into a housing to expose the air to UV radiation to produce ozone molecules that have an oxidizing effect on organic matter and the UV radiation serves as a germicide and a virucide. The ozonated and oxidized gases are exhausted through a carbon filter.Type: GrantFiled: March 14, 2007Date of Patent: April 24, 2012Assignee: Zuvo Water, LLCInventors: Raymond P. Denkewicz, Jr., Rolf Engelhard

Patent number: 8066940Abstract: Simultaneous application of ozone and ultraviolet light (UV185 and UV254) in water to be purified will create hydroxyl radicals, which combination will cause conversion of AS (III) that may be present to As (V), oxidation of inorganic matter such as manganese, sulfur, phosphorus and organic matter and provide virucidal and germicidal effects to purify the water.Type: GrantFiled: June 28, 2007Date of Patent: November 29, 2011Assignee: Zuvo Water, LLCInventors: Raymond P. Denkewicz, Jr., Rolf Engelhard

Patent number: 8066941Abstract: A pressurized water tank having a head space includes a pump for recirculating the water through a nozzle disposed in the head space. The out flowing stream of water will entrain air and cause mixing of air entrained water with the remaining water in the tank. To enhance air entrainment and convey the air entrained water to a location well below the water level, the stream of water is injected into a vertical venturi tube. The entrained air will have an oxidizing effect upon organic matter and also cause circulation of the water within the tank. To enhance oxidation of organic and inorganic matter, a UV lamp may be located in the head space to convert oxygen molecules in the air into ozone molecules. Such ozone molecules would be entrained in the stream of water flowing out of the nozzle and into the tube and have a strong oxidizing effect upon organic and inorganic matter.Type: GrantFiled: June 28, 2007Date of Patent: November 29, 2011Assignee: Zuvo Water, LLCInventors: Raymond P. Denkewicz, Jr., Rolf Engelhard

Patent number: 8048316Abstract: A method for subjecting a microorganism to a combination of ozone and irradiation of UV light which has a synergistic effect on the reduction of the microorganism that may be resistant to either ozone or UV light alone. In particular, Adenovirus and Naegleria fowleri, are significantly more reduced when subjected simultaneously to the combination of ozone and UV light than when subjected only to ozone or UV light, respectively.Type: GrantFiled: March 28, 2007Date of Patent: November 1, 2011Assignee: Zuvo Water, LLCInventor: Raymond P. Denkewicz, Jr.

Patent number: 7794608Abstract: Water within a water tank is irradiated with ultraviolet light from a UV lamp for virucidal and germicidal purposes while simultaneously transforming oxygen molecules to ozone molecules in an oxygen containing gas flowing within an annular space defined by a sleeve surrounding the UV lamp. The ozone enriched gas flows into an enlarged chamber into which the UV lamp extends and the flow rate is reduced to enhance the time of exposure of the ozone enriched gas to UV radiation and thereby enhance the production of ozone. To increase the rate of transformation of oxygen molecules to ozone molecules, the gas is under a predetermined pressure prior to entering the annular space and subsequent to discharge from the chamber.Type: GrantFiled: June 28, 2007Date of Patent: September 14, 2010Assignee: Zuvo Water, LLCInventors: Raymond P. Denkewicz, Jr., Rolf Engelhard

Patent number: 7055823Abstract: The present invention relates to educational and entertaining playing cards. The cards may be used alone or in combination with other hardware game accessories, such as board games, or software game accessories, such as compact discs and the Internet. Unlike other popular and heavily traded playing cards (e.g. Pokemon) which have limited social and educational value, an educational element has been added to the cards of the present invention without destroying the fun associated with the collecting, trading, and playing of the cards. Educational facts and information about a variety of topics are located on the playing cards, which may be used to play various games. Two different types of game cards are contemplated by the present invention: (1) standard cards and (2) fact cards. The present invention, however, is in no way limited to only these two types of game cards.Type: GrantFiled: November 25, 2002Date of Patent: June 6, 2006Inventor: Raymond P. Denkewicz, Jr.

Fluid flow diverters and diversion methods and water purification equipment including such diverters
Patent number: 6680026Abstract: “Plug-in” fluid flow diverters are disclosed. Additionally disclosed is water purification equipment adapted to communicate with the diverters. Such equipment is especially (although not solely) useful in connection with circulating streams of water present in systems associated with swimming pools, hot tubs, and spas, as the circulating nature of the water permits more of its volume ultimately to be diverted into the equipment for purification. The diverters, furthermore, may have entrances oriented to receive fluid travelling in only one direction through a conduit and be keyed to one or more components of the equipment for purposes of identification, inventory control, or otherwise.Type: GrantFiled: May 5, 1999Date of Patent: January 20, 2004Assignee: Zodiac Pool Care, Inc.Inventors: Raymond P. Denkewicz, Jr., Alvin Costa, Daniel J. Nelsen, Michael C. Pereira, Justin W. Sirotin, Michael Vieira, Aidan J. Petrie -

Patent number: 6217780Abstract: The present invention is directed to a biocidal water treatment composition, water treatment apparatus, and method of treating water to reduce levels of pathogens. The composition contains sources of copper, zinc, and silver metal ions within a crosslinked polymer matrix. Examples of these ion sources include copper sulfate, zinc sulfate, and silver nitrate. An example of the crosslinked polymer matrix is crosslinked chitosan, which also serves to clarify the water and release the metal ions over time. The product is easy to manufacture, and allows the use of decreased halogen sanitizer, as well as decreased copper ion, thereby decreasing the likelihood of staining. The product simultaneously provides good bactericidal and algaecidal properties, despite low levels of copper ion and low chlorine levels.Type: GrantFiled: December 28, 1999Date of Patent: April 17, 2001Assignee: Zodiac Pool Care, Inc.Inventors: Raymond P. Denkewicz, Jr., Ernest E. Senderov, Joseph W. Grenier
