  • Patent number: 8968576
    Abstract: A method of treating contaminated air, gas and surfaces is accomplished through the nebulization of gas and/or liquid oxidants through a field of electromagnetic radiation or sonic waves. The contaminated gas and/or liquid streams are blended with gaseous and/or liquid oxidants by the nebulizer and directly injected in the energy field. Free radicals produced from oxidants in the presence of the energy field instantaneously oxidize a large effective surface area of the contaminated media. Surfaces are treated more efficiently with the energy field situated directly above and parallel to but not on the surface; a high-frequency energy field may be used to create a large concentration of free radicals without damaging the surface in a collimated beam of the field situated parallel to the surface. A catalyst may be employed at the tip (i.e. discharge orifices of gas and/or liquid) of the nebulizer or blended into the nebulized cloud to increase the formation of free radicals.

  • Patent number: 7794608
    Abstract: 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.

  • Publication number: 20100133202
    Abstract: This invention presents the set-up of a heterogeneous photo-Fenton system for the abatement of organic pollutants in liquid wastewater by means of heterogeneous perovskite-based catalysts, both in powder and in structured form. The proposed method employs, preferably, structured honeycomb monoliths consisting of a perovskite-based material (unsupported catalyst), or structured honeycomb monoliths made of a refractory carrier or a foam impregnated with a solution of salts corresponding to the desired perovskite (supported catalyst). The removal of organic substances is carried out at room temperature and atmospheric pressure, through an oxidation to gaseous CO2. The perovskite-based catalyst, in structured form, is more efficient in the degradation of organic pollutants than a homogeneous photo-Fenton catalyst. It allows to enlarge the operative range of pH in comparison to the limited operative range of pH of the homogeneous system, without the formation of sludge.
