Abstract: A method for making surface corona discharge, which produces ozone gas and apparatus for producing the same are disclosed, in which a dielectric spacer/film having a specific capacity Cnull equal to or more than 200 nanofarad per square meter positioned between the base electrode and the net electrode. Said net electrode is a wire net or a perforated metal or a wire winding having an open area not less than about 70%, and a size of hole D equals to or less than about 0.7V/P, where V is a voltage in kilovolts and P is pressure of an ambient air or an oxygen in atmospheres. Net electrode has radius R of wire or radius of an edge of openings in the perforated metal equal to or more than about 1.6d, where d is the thickness of the said dielectric spacer/film, which is determined by a fundamental formula dnull9k/Cnull, where d is in millimeters, Cnull is in nF/m2, and k is dimensionless dielectric constant k of given material. Under disclosed parameters said surface corona is safe for human contact if said net electrode is grounded. Start voltage Vst of ozone production is determined by experimental formula Vstnull0.7null60/Cnull, kV, here Cnull in nF/m2. The even and high intensity corona surface and high ozone output takes place if the operating voltage is more than about 3Vst. AC power supply is applied to produce ozone gas at nullhomenull voltage 0.7-1.0 kV and produces ozone gas more effectively at 2,5-3.6 kV. A method for disinfection and decontamination of objects by using the direct corona contact and apparatus for making the same is disclosed, in which safe corona surface is placed on said object and is acting by ozone, ultraviolet and ion bombing simultaneously in the unique environment, which takes place inside of the safe corona. A method for ozone disinfection and decontamination and devices for making the same is disclosed, in which said ozone generating element is placed in a closed container/room with or without treated objects and produce a high ozone concentration due to effective ozone dispersion from corona surface without blowing of air/oxygen through said container/room.

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.

Abstract: A method of manufacturing a corona discharge device suitable for use as an ozonizer capable of producing a controlled small amount of ozone throughout a prolonged service life. A foreproduct of corona discharge device (50) is first prepared which is provided with first and second planar electrodes (54; 56) capacitively coupled with each other by a third floating electrode (64) which is coated by a protective layer (68) of chemically-resistive electrically-insulatingmaterial. A high frequency alternating voltage having a voltage level higher than an initial minimum flashover voltage level of the foreproduct is then applied until the protective layer is aged. Aging of the protective layer is effective in lowering the initial minimum flashover voltage of the final product thus obtained as well as in reducing any fluctuation of the initial minimum flashover voltage that would otherwise occur from product to product. Various other features are also disclosed.

Abstract: The apparatus described is intended for the treatment of small volumes of room air for the removal of odors. Since the ozone output of the apparatus is calibrated in terms of the readily measured corona current, this type of apparatus can be intelligently applied to odor control problems. If the volume to be treated is known, then the output in mg/hr necessary to produce ozone backgrounds of 0.04 ppm and below can be readily computed. Such concentrations are comparable to the natural background and generally acceptable for continuous human occupation.

Abstract: An improved ozone generator for small portable systems formed in the shape of a replacable module. The high voltage electrode in the center of the generator is of a boxlike construction with one end open towards the generator outlet port and with the sides made from perforated stainless steel in order to supply multiple outlets for the formed ozone from the corona discharge gap, which will reduce the amount of dissociation of ozone and the amount of nitric acids formed. The high voltage electrode is suspended in the center of the generator by means of 4 ceramic spacers. The potential area of surface contamination caused by impurities in the feed gas and leading to generator failure is therefore limited to the said spacers.The generator has removable thermal pads that are used in order to retain the heat in applications where the generator produces small amounts of ozone, otherwise they are removed to allow for air cooling.The whole generator assembly is held together with two U-shaped spring clips that can be removed without the use of tools. This makes the cleaning process a fast and efficient operation.

Abstract: In an internally cooled tubular ozonizer, there is built into the interior of the glass tube (5) a cooling tube (9) whose outer diameter is only slightly smaller than the inner diameter of the glass tube (5). The annular gap left is filled up with a temperature-resistant casting compound (10) which conducts heat well. In the case of a synthetic resin casting compound (10), the cooling tube (9) is connected galvanically via contact springs (11) to the metal layer (8), serving as the inner electrode, on the inner wall of the glass tube (5). The heat transfer from the cooling agent in the cooling tube (8) to the glass tube (5) is not impeded by the casting compound (10). Temperature stresses between the glass tube (5) and the cooling tube (9) are largely reduced, as a result of which the operational safety of the ozonizer is increased, especially at fairly high power densities.

Abstract: In modern ozone generators high power densities can be achieved using ceramic-based dielectrics and suitable gap widths and double cooling. By constructing the dielectric layer from dielectric powders of different grain size and binding with artificial resin, the long-term breakdown voltage of the dielectric layer can be increased to such an extent that they fulfil the operating requirements.
