20080237108 | Acid mine water demineralizer - The acid mine water demineralization apparatus consists of two concentric cylinders that are divided into a total of four sections; a water chamber, a gas chamber, a reaction zone, and an aeration zone. The water chamber transports acid mine water to the inlets of a plurality of the sharp edged orifices. The gas chamber receives ozone from an external source and sends it through a porous plate into the reaction zone, thus ensuring the gas is dispersed uniformly throughout the reaction zone. Water passing through the sharp edged orifices into the reaction zone reacts with the ozone to oxidize the insoluble metals in the water. Exiting the reaction zone, the water enters into the aeration zone where additional oxygen is added to the water and the agitation of the water is calmed before it enters a settling tank. | 10-02-2008 |
20090120863 | MINIATURE OZONE GENERATOR AND USE THEREOF FOR PURIFYING WATER - The present invention concerns a miniature ozone generator device for purifying water.

The electrodes have rough surfaces, whereby, in use, when the ozone generator is plunged into a vessel containing the water to purify, the electrodes thanks to their rough surfaces, leads to a coalescence of hydrogen bubbles produced by the cathodes into larger hydrogen bubbles, and thus to a higher production of ozone by the anodes. Hydrogen can be additionally removed by absorption of it thanks to a conductive material used to make the cathodes, which can be regenerated for reuse. The invention also concerns the use this miniaturized ozone generator for purifying water or the like and methods for doing the same. | 05-14-2009 |

20110247972 | Pressurized UV/O3 Water Purification System - An oxygen containing gas is injected at a pressure in the range of about two (2) to about five (5) atmospheres or more into an ultraviolet transmissive sleeve surrounding an ultraviolet lamp to produce a high concentration of ozone. Simultaneously, the ultraviolet lamp irradiates water to be purified disposed in a container surrounding the sleeve. The ozone enriched gas is entrained into the water flowing into the container resulting in an oxidative reaction with any organic matter present and coming into contact with the ozone. Alternatively, the ozone may be entrained in water in a second container downstream of the container wherein the water has been irradiated with ultraviolet radiation. In a further variant, the ozone may be entrained in water in a container upstream of the container wherein the water has been irradiated with ultraviolet radiation. In a yet further variant, the ozone may be entrained in one or more containers upstream and prior to irradiation of the water with ultraviolet radiation in the downstream most container. The ozone may be extracted from the ozonated water prior to discharge if the oxidative effect of the ozone is not desired for the intended end use. To enhance ozone production a predetermined pressure is maintained within the sleeve. To prevent damage to sleeve in the event of a drop in pressure of the water surrounding the sleeve, a further differential pressure regulator may be used to relieve the pressure within the sleeve by discharging ozonated gas from within the sleeve. By use of specifically configured end caps for the sleeve, certain existing water purification systems may be converted to embody the present invention. | 10-13-2011 |

For the said device to become commercially viable, the scale buildup, particularly calcium carbonate, on the cathodes must also be resolved. Tests have shown that the provision of a low vacuum over the electrodes of electrolyzer can assist the device to deliver a consistent ozone throughput for a long period of time.
