Abstract:
A household apparatus for treating water has a water treatment reactor; a dispense water path extending from the water treatment reactor to a dispenser whereby treated water produced in the water treatment reactor exits the apparatus by the dispenser; a filter removably mounted in the dispense water path; and, a sensor, (which may be a timer, a flow rate sensor and/or a back pressure sensor) for monitoring the flow of a treated water through the filter, the apparatus issuing a signal advising a user to change the filter when the time for the treated water to flow through the filter exceeds a predetermined value.
Abstract:
In a method of removing organic contaminants from a liquid, an oxidizing gas is formed into sub-micron size bubbles which are dispersed into an initially contaminated liquid, after which the treated liquid is recovered. The oxidizing gas is preferably selected from a group including ozone and chlorine dioxide and is utilized immediately upon its manufacture. An oxidizing liquid may be employed in conjunction with the oxidizing gas.
Abstract:
A method for treating a liquid (e.g. water) with a gas (e.g. air) containing ozone includes passing air through an corona discharge ozone generator to produce air containing ozone and introducing the air containing ozone into the liquid; and, periodically de-energizing the ozone generator and passing air through the ozone generator.
Abstract:
The invention provides a pair of parallel megasonic transducers that generate parallel columns of megasonic waves across a cleaning container. Semiconductor wafers move back and forth transverse to the columns. The transducers have their back side potted with a silicone elastomer to prevent corrosion. In another embodiment megasonic waves from in-line transducers are dispersed with a cylindrical quartz rod. Water is enriched with ozone by pumping ozone under pressure through a filter into sealed housing of deionized water.

Abstract:
The invention relates to a method for treatment of fluids, the invention being characterized in that ozone is generated in the medium, which ozone is exposed to UV radiation at the same time as it is being generated, so that the ozone is broken down and free radicals are obtained. The invention also relates to an apparatus in accordance with the method, which apparatus comprises an enclosure (1) provided with at least one inlet (2) and at least one outlet (3). The apparatus is characterized in that an oxidizing member (4) is arranged in the enclosure (1) and generates ozone and at the same time breaks down the ozone to free radicals.
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:
An ozone storage apparatus is disclosed for storing ozone efficiently. A process for efficient water treatment is also disclosed. The ozone storage container has a generally U-shape and is filled with an absorbent. The ozone is supplied and discharged from the same opening. The temperature of the absorbent is kept between 0null C. and null30null C. The generated ozone from an ozone generating means is cooled by a cooling device and is supplied to a storage device.
Abstract:
In a method of improving the quality of diesel fuel, an oxidizing gas is formed into sub-micron size bubbles which are dispersed into diesel fuel, after which the treated fuel is recovered. The oxidizing gas is preferably ozone and is utilized immediately upon its manufacture. By means of the method, sulfur is removed from the diesel fuel and the cetane rating thereof is increased.
Abstract:
An ozonizer and water purifier equipped with the ozonizer comprising an ozonizing discharge element; an electric circuit for applying a voltage to the ozonizing discharge element so as to produce an ozone-generating discharge; a housing having an opening formed therein for receiving the ozonizing discharge element; a cover which seals the ozonizing discharge element in the housing; and a device for turning off the voltage applied to the ozonizing discharge element when the cover is removed. In another embodiment, at least a part of the cover or housing is transparent so as to enable detection of the discharge state of the ozonizing discharge element. Also disclosed is an ozonizer and a water purifier comprising the ozonizer which includes a discharge element for generating ozone by discharge, wherein ammonium nitrate and other substances adhere to the discharge element upon discharge; and a heat generating element for heating the discharge element to a predetermined temperature which induces scattering of at least ammonium nitrate molecules among those substances adhering to the discharge element.
