Abstract:
Method and system are disclosed for coupling energy from at least on energy source, e.g. UV light source, ultrasonic transducer, or combination thereof, to a target site, e.g. hazardous bacteria, through a streaming liquid, e.g. water. The bacteria toward which energy is to be coupled could be present in the water stream itself and/or on a surface toward which the water stream is to be launched at the end of its flow. Accordingly, in-line aseptic filling is provided, which can fill and simultaneously disinfect a container. According to another embodiment where the water is used for washing, in-line aseptic washing device is provided. A variety of other embodiments is disclosed as well.
Abstract:
The invention relates to a pulsed electric field sanitization system that may be used for sanitization of liquids, such as drinking water. The system optionally includes a double check valve to allow simultaneous flow of water into and out of components of the system. The system may be used in combination with other purification technologies. A further embodiment of the invention relates to a stand-alone drinking water purification device.
Abstract:
An ozone water producing device for producing ozone water having a sterilizing power by mixing ozone-air into untreated water. A valve housing 11 has a water flow-in port 11c which communicates with a city water faucet to admit city water therethrough, a water flow-out port 11d via which city water flows out, and a valve disc housing cylinder 11b formed with an ozone flow-in port via which ozone-air flows in. The valve disc housing cylinder 11b is mounted with a rotatable cylindrical valve disc 13 thereon, and a negative pressure generating chamber 14 is formed in the valve disc 13. An operating lever 16 linked to the valve disc 13 sets the valve disc 13 to an ozone water supply position that allows the water flow-in port 11c to communicate with the water flow-out port 11d and the ozone flow-in port to communicate with the negative pressure generating chamber 14. The negative pressure generating chamber 14 communicates with an ozone generator case housing an ozone generator therein.
Abstract:
A method and apparatus for electrolytically producing oxidation reduction potential water from aqueous salt solutions for use in disinfection, sterilization, decontamination, wound cleansing. The apparatus includes an electrolysis unit having a three-compartment cell (22) comprising a cathode chamber (18), an anode chamber (16), and a saline solution chamber (20) interposed between the anode and cathod chambers. Two communicating (24, 26) membranes separate the three chambers. The center chamber includes a fluid flow inlet (21a) and outlet (21b) and contains insulative material that ensures direct voltage potential does not travel through the chamber. A supply of water flows through the cathode and anode chambers at the respective sides of the saline chamber. Saline solution flows through the center chamber, either by circulating a pre-prepared aqueous solution containing ionic species, or, alternatively, by circulating pure water or an aqueous solution of, e.g ., aqueous hydrogen chloride and ammonium hydroxide, over particulate insulative material coated with a solid electrolyte. Electrical current is provided to the communicating membranes separating the chambers, thus causing an electrolytic reaction that produces both oxidative (positive) and reductive (negative) ORP water.
Abstract:
Water treatment systems or assemblies are normally tested after construction, at least for leaks, prior to shipping or storage. Pressure testing with a gas is hazardous, so testing with water is a standard method. After testing, the water is displaced from the system by draining or gas phase flushing. It is nearly impossible to remove all of the water from the system or assembly. This remaining water provides an environment for biological growth which contaminates the system or assembly over time. The purpose of this invention is to eliminate or minimize this biological contamination by adding a biocidal agent to the system or assembly before sealing it for shipment or storage.
Abstract:
The present invention is a device and method for ozonating water and applying the ozonated water to surfaces for cleaning purposes. The instant invention allows a user to transform water into a liquid with more robust cleaning properties conveniently and in a short time. The present invention includes a cleaning apparatus having a reservoir (64) containing water, the reservoir able to be easily manipulated by a user to dispense the water, and a circulation flow path communicating with the reservoir and the device to allow at least some of the water in the reservoir to flow from the reservoir to the device and back to the reservoir.
Abstract:
The invention relates to the cleaning of articles, more specifically to devices for liquid cleaning of non-chemical impurities and can be used for domestic washing machines and for disinfecting cleaned articles. The inventive device for liquid cleaning comprises a hermetic reservoir having a washing zone and a vacuum zone. Said reservoir is provided with orifices circumferentially arranged below the separation between the washing zone and the vacuum zone. The device is also provided with a unit for evacuating the washing fluid and a unit for automatically supplying the washing fluid and atmospheric air, said units being arranged outside the cleaning area. Drainage holes are embodied in such a way that they enable a gutter encompassing them to evacuate the used washing fluid through the centrifuge. Safety grids made of various materials and forming galvanic couples are arranged inside the reservoir. The invention enables a washing fluid to be transported without contacting a mechanical unit, and makes it possible to carry out automatic program control of a cleaning process by means of cold boiling.
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.
