Abstract:
An in-line reactor for the treatment of liquids or gasses by light radiation is disclosed. The reactor is made of tube, pipe, or chamber made of a transparent material, having at least one fluid inlet and correspondingly at least one fluid outlet. The transparent material of the tube is selected such that its refractive index is as possible close to the refractive index of the fluid to be treated. Air gap is kept around the outer transparent walls of the reactor, in order to allow for total internal reflection inside the reactor, of light directed into it from a light source in angles of incidence greater than the critical angle. Fluid treatment systems comprising at least one said in-line reactor are also disclosed. Furthermore, method of in-line fluid treatment, and especially of water sterilization and disinfection and aseptic filling of water are disclosed. Surfaces hit by the in-line disinfected water after being launched through an outlet nozzle, could also be sterilized by launching the water with the same UV light used for the in-line treatment locked in total internal reflection within the free flow water jet.
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 (1326) 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:
A multi-use sanitization system is disclosed which includes one or more containers in fluid communication with other system components. Components of the system include a vortex-venturi for incorporating ozone into a liquid, an ozone generator to provide ozone to the vortex-venturi, a double check valve to allow simultaneous flow of liquid into and out of the container, and a pump to promote fluid flow through the system. Optionally, a gas-liquid separator with an optional integral gas release valve, an ozone destructor, an oxidation-reduction potential ozone sensor, or a pour-through type pre-filter may be incorporated into the system.
Abstract:
This ozone appliance for the professional dental office and other medical applications introduces dissolved ozone into dental and surgical operatory water lines. This dissolved ozone can not only disinfect water and water lines; it can also reduces gum bleeding, gingivitis, bad breath, teeth stains and oral bacteria. Additionally, it can aid in wound disinfection in surgery and attack microbial contamination of water from dental and surgical oparatory water lines and attached hand pieces and dispensing devices by automatically killing waterborne germs and destroying biofilms where germs can hide and grow. It can, therefore, be used to disinfect water lines in dental operations and for other medical applications such as providing liquid containing ozone for cleaning and disinfecting skin prior to surgery (and tissue exposed during surgery). Further, a unit connected to operatory water lines can give an audible or other alarm if the water becomes unsafe.
Abstract:
This portable appliance can be used to clean teeth by a liquid containing dissolved ozone.Preferably, its cleaning action is enhanced by pulsations of the liquid stream. The dissolved ozone can reduce or eliminate gingivitis, gum bleeding, bad breath, teeth stains, and harmful oral bacteria. This appliance can also be used for nasal irrigation for sinusitis treatment and for ear irrigation, eye care, and general cleaning. Additionally, since its output pump (34) is independent of the ozone dissolving system (19), the ozone dissolving system can be configured as an add on device for an oral irrigator such as a Water PikTM. In this configuration, the ozonated liquid is delivered by either gravity or pumped flow, to a reservoir in connection with the irrigator (35) that serves as the delivery portion of this invention.
Abstract:
A general method and apparatus for treating materials comprising the steps of dissolving ozone gas in a solvent at a predetermined temperature T1 to form an ozone solvent solution produced by the ozonated water supply (22), heating the ozone solvent solution by a heat exchanger (28) to a second predetermined temperature T2 which is greater than T1, and directing the flow of the ozone solvent solution to a dispensing nozzle (36) for treatment of the material (38).
Abstract:
A chamber (10) is supplied with a pressurized cleaning agent of carbon dioxide and cosolvents from a first source (12) and an antimicrobial fluid, such as ethylene oxide or hydrogen peroxide from a second source (16). Chamber conditions are maintained in the sub-critical range for the carbon dioxide. The cleaning agent and antimicrobial fluid are recirculated through a separator (32) and a condenser (38) to filter contaminants from the mixture before returning the carbon dioxide, and optionally the antimicrobial fluid and other additives, to the chamber. Medical instruments or other articles within the chamber are cleaned by the cleaning agent and sterilized by the antimicrobial fluid in a single cycle, rendering them ready for reuse in a short period of time. The instruments may be cleaned and stored in hermetically sealable containers (82). The cleaning agent is rapidly evaporated from surfaces of the articles at the end of the cycle by reducing the pressure in the chamber. Optionally, a vacuum pump (60) assists in removing the antimicrobial fluid from the chamber.
Abstract:
A method (10) for cleaning an article, such as a used kidney dialyzer (12), requiring sterilization includes the steps of manually rinsing the article with purified water (26), inserting the article into an automated reuse apparatus (28) which utilizes ozonated water, and sterilizing the article for a predetermined period of time with ozonated water (32) wherein the ozonated water flows through the article for sterilizing it. The step of inserting the article into the automated reuse apparatus (28) includes the steps of rinsing the article with ozonated water, reversing the flow of ozonated water through the article for backwashing the article, and conducting testing cycles wherein the article is tested for leaks therein and for ensuring it can contain a predetermined quantity of fluid. Preferably, the predetermined period of time of the sterilizing step is approximately thirty minutes. An apparatus (28) for producing ozonated water is further disclosed.

Die Erfindung betrifft ein Verfahren zur Entkeimung einer Tauchbadflüssigkeit,insbesondere eines kathodischen Tauchlackes. Es ist vorgesehen, dass die Entkeimung ohne Zugabe von Ozon in die Tauchbadflüssigkeit erfolgt.
Abstract:
A device for producing ozonated water from water is provided, the device comprising a vessel for containing water and having an inlet and an outlet; an electrochemical cell assembly operable to electrolyse water in the vessel to produce ozone and having a first electrode assembly and a second electrode assembly; a sensor for detecting the presence of ozone in solution in the water in the vessel; and a processor for receiving an indication from the sensor and determining if the concentration of ozone in the water is below a threshold value and, if the concentration is below the threshold value, activating the electrochemical cell. A method for producing ozonated water is also provided.
