| 20090120863 | MINIATURE OZONE GENERATOR AND USE THEREOF FOR PURIFYING WATER - The present invention concerns a miniature ozone generator device for purifying water. The device comprises a printed circuit board having an ozone producing circuit printed on it which comprises anodes and cathodes alternatively printed and connected in parallel relationship to each other and to a power supply device. 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 |

| 20120223000 | VACUUM ASSISTED OZONIZATION - Ozone is a powerful and versatile oxidant that is good for many applications including sterilization of drinking water, rejuvenation of waste waters, and chemical syntheses. Most of the man-made ozone for the said uses comes from corona discharge of oxygen gas. From the aspects of simplicity, efficiency, voltage level and space area, generation of ozone by water electrolysis has all advantages over the discharge means. It requires an catalyst deposited on the anode of electrolyzer for generating ozone gas directly in water, and the anode material should be affordable, long-lived and reliable. 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.

| 20110186493 | ORGANIC ECO-AGRICULTURAL WATER SYSTEM - An organic eco-agricultural water system includes a water source, a water discharge device connected to the water source by a pipeline, and ozone generators installed in the pipeline between the water source and the water discharge device and controlled to generate ozone and to supply generated ozone to the water flowing through the pipeline proportionally subject to the flow rate of the water passing through the pipeline. The discharged water can be used for application on crops or for the purpose of irrigation to save consumption of agricultural chemicals. | 08-04-2011 |
| 20110056876 | DESALINATION SYSTEM - Certain embodiments provide a desalination system including a desalination plant, a carbon dioxide contacting plant, a carbonate filtering plant, and an electrolysis plant. The desalination plant works to separate raw water into fresh water and high salinity condensed water. The carbon dioxide contacting plant works to bring carbon dioxide into contact with condensed water obtained at the desalination plant, producing carbonates. The carbonate filtering plant works to filter carbonate containing condensed water produced at the carbon dioxide contacting plant, effecting a carbonate removal from condensed water. The electrolysis plant works for an electrolytic treatment of condensed water after the carbonate removal at the carbonate filtering plant to produce a chemical or chemicals for use in the desalination system. | 03-10-2011 |
| 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 |

| 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 |
| 20120125830 | PORTABLE OZONATION APPARATUS FOR STORING AND PURIFYING LIQUID - A portable ozonation apparatus for storing and purifying liquids includes a container having an opening for receiving a liquid and a treatment cap.

Preferably, the treatment cap includes a main body portion having provided therein an electricity generating device and an ozone generating device. With this arrangement, un-purified liquid, such as water, is introduced into the container. The container is then inverted to bring the un-purified liquid into contact with the ozone generating device. At this point, the electricity generating device is activated to deliver an electrical current to the ozone generating device. Once powered, the ozone generating device produces ozone which is introduced into the liquid container. The ozone gas transforms un-purified liquid into a purified liquid suitable for consumption. | 05-24-2012 |
