Abstract:
A system comprising an ozone generator for generating ozone and a venturi for mixing the liquid to be ozonated with the generated ozone. The ozone generator is coupled to an orifice for supplying the generated ozone thereto. A pump is coupled to an outlet of the reservoir for pumping liquid to be ozonated from the reservoir to venturi. An outlet of the venturi is connected to a return inlet of the reservoir for supplying ozonated liquid back to the reservoir. A mixing chamber interconnects the outlet of the venturi to the return inlet of the reservoir, and the mixing chamber facilitates adequate mixing of the ozone supplied to the liquid to be ozonated and facilitates substantially complete dissolving of any remaining ozone bubbles and ozone pockets within the liquid to thereby result in substantially uniform mixture of ozonated liquid for supply back to the reservoir having an increased contact rate of ozone to liquid of about 80% to 90%.

Abstract:
A system and method for treating water to be used for irrigation. The system and method utilizes an apparatus for generating ozone and other atoms and molecules resulting from the bombardment of a feed gas with electrons has, preferably, a first electrode positioned within a channel in a second electrode. The first electrode is a substantially sealed tube made of dielectric material, having at least one electron gun positioned proximate an end thereof for firing electrons into the first electrode. In electrical communication with the electron gun is a rod, maintained in a tube also made of dielectric material, which acts to maintain a constant energy level through the length of the rod and thus the length of the electrode. Within the first electrode is an inert gas which, upon the firing of the electron gun, is formed into a plasma. When a feed gas (generally air) is passed between the first and second electrodes, the electrons and plasma cause the formation of ozone and other atoms and molecules in the feed gas, which products have beneficial uses in the treatment of water and air for different purposes. The treated feed gas is then injected, preferably with a venturi type of injector, into the water to be treated.

At low voltages, it can generate and maintain stable, low-temperature plasma over a large area. The plasma is suitable to form radicals of high energy and can be used for bonding, polishing, cleaning, thin films deposition, sterilization, ozone generation, printing, dyeing, etching, purification of water and air, complete combustion of fuels, manufacture of highly luminous lamps.
