Abstract:
An ozone water purification system is disclosed. In this system, ozonated water flow proceeds alternately upwardly and downwardly through a series of vertical tubes. In order to disturb the laminar flow within the tubes, several types of turbulence-inducing devices may be mounted within the tubes. Such a mounting may be made so that the devices are removable for cleaning. In addition, the tubes may be circularly arranged so as to conserve space.
Abstract:
Disclosed is a process for producing ozone-containing sterilizing water and apparatus used in the process. Ozone-containing sterilizing water can be continuously produced by maintaining a mixture of raw water and ozone gas under a predetermined pressure and time with the use of two separate compartments of a compression mix.
Abstract:
Methods of using ozone have been developed which sterilize instruments and medical wastes, oxidize organics found in wastewater, clean laundry, break down contaminants in soil into a form more readily digested by microbes, kill microorganisms present in food products, and destroy toxins present in food products. The preferred methods for killing microorganisms and destroying toxins use pressurized, humidified, and concentrated ozone produced by an electrochemical cell.
Abstract:
A module containing a pair of generally concentric cylinders with a dielectric cylinder disposed therebetween is connected to a source of air under pressure to provide an air flow intermediate the concentric cylinders and on either side of the encircled dielectric cylinder. Clips, connected to a source of high voltage, detachably engage the outer cylinder and a boss electrically connected to the inner cylinder to provide a voltage potential between the generally concentric cylinders of sufficient magnitude to cause an electrostatic discharge through the space therebetween. The use of an electrically high resistance dielectric cylinder between the generally concentric cylinders will tend to provide a uniform electrostatic discharge along the length of the generally concentric cylinders. The oxygen molecules within the air flow between the generally concentric cylinders will be converted, to some extent, to ozone molecules and provide an ozone enriched air flow into a plenum and an outflow therefrom through tubing to a point of use. As the module is readily detached from its mechanically and electrically associated clips, it is readily replaced in the event of malfunction. Moreover, the electrically conducting cylinders may be of inexpensive metallic tubing and the dielectric cylinder may be inexpensive glass tubing. The electric circuitry providing a voltage potential sufficient to produce electrostatic discharge is primarily an inexpensive step-up transformer.
Abstract:
An apparatus and method for generating ozone is provided. An ozone generator comprises a substantially transparent element having ozone-generating means mounted on an inner element area and an outer element area. An enclosure is positioned over the element, and an oxygen-containing gas is directed through the inner element area, creating ozone from a portion of the oxygen-containing gas. The ozone and oxygen-containing gas is then redirected over the outer element area, so that the oxygen-containing gas is at least twice exposed to the ozone-generating means, thereby generating additional ozone.
Abstract:
An aqueous ozone generator with reverse osmosis or deionization function includes an ozone generator and an ozone monitor connected with the outlet end of a reverse osmosis circuitry. The reverse osmosis circuitry can be replaced by a deionization circuitry. The ozone generator produces ozone which is then diffused to the pure water making the aqueous ozone solution with ozone level above 1 ppm. As a disinfectant, aqueous ozone solution is applied to water for washing food, dishware, wound and medical devices.
Abstract:
A photocatalyst module comprising a substrate, for example, a metallic substrate, a layer of a photocatalyst such as titanium oxide, and a protective layer containing lithium silicate provided between the substrate and the layer of a photocatalyst wherein the protective layer can sufficiently withstand the heat in a step for forming the layer of a photocatalyst by a flame spray coating method and can prevents oxidation and/or decomposition of the substrate is disclosed.
Abstract:
The invention provides for the generating of a corona or other electric discharge and provides for the passing of a gas through the corona to effect ionizing, creating of ozone or the like. The ionized gas, ozone, etc., may be used for various purposes, such as the disinfecting of water or some other material, the filtering of one material, such as iron, minerals, or other materials, from another or other function. According to various methods of the invention, a corona discharge (or other electric discharge) is created, a gas is passed through the corona discharge; mixing of the gas may be provided by motionless mixing technique for one or more purposes, such as to assure maximum exposure of the gas to the corona discharge, to provide uniform temperature of the gas, to cool the corona generator, etc. According to one of the methods, too, a corona generator has an equivalent circuit of a plurality of capacitors, which may be charged in series and rapidly discharged in parallel.
Abstract:
A microporous diffuser includes a first elongated member including at least one sidewall having a plurality of microscopic openings. The sidewall defines an interior hollow portion of the member. The diffuser has a second elongated member having a second sidewall having a plurality of microscopic openings, the second member being disposed through the hollow region of the first member. The diffuser includes an end cap to seal a first end of the microporous diffuser and an inlet cap disposed at a second end of microporous diffuser for receiving inlet fittings.
Abstract:
Service water is filtered by an active carbon pre-filter. The pre-filtered water is forced into a reverse osmosis membrane by a pump to produce pure water, and the pure water is processed to remove specific substances that consume ozone. Then, an ion-exchange resin treats a part of the low-ozone-consuming water and removes electrolytes from it to produce proper ultrapure water, which is supplied through a gas-liquid separating vessel to an electrolysis cell to produce ozone-containing gas. Another portion of the liquid in a lower space in the vessel is sent through a line to a separate temperature-controlled container. The returned liquid is mixed with the gas from the electrolysis cell by using an aspirator and ejector. Part of the high-concentration ozone water can be supplied through the temperature controlled container, a solenoid valve and a needle valve to an ozone water discharge device.
