Abstract:
The present invention is an apparatus and method of employing an electrolysis cell assembly for producing simultaneously various diluted Hypochlorous Acid solutions and simultaneously a diluted Sodium Hydroxide solution for usage as cleaning and sanitation by electrolysis of an aqueous saline solution. The apparatus comprising a cylindrical three chamber electrolysis cell consisting of an inner chamber, a middle chamber and an outer chamber having two middle mesh-electrodes in the middle chamber wherein ion-selective exchange membranes are sealed around or on the inside of the middle mesh-electrodes to separate the middle chamber from the inner and outer chamber. The method allows production of different concentrations of Sodium Hydroxide and Hypochlorous Acid solutions isolating a Sodium Hydroxide solution having a negative redox potential ranging from −600 to −1200 mV and isolating a diluted Hypochlorous Acid solution having a positive redox potential ranging from +700 to +1200 mV.
Abstract:
The invention relates to an apparatus and method for distilling fresh water from sea, and brackish water. In essence, an invented, Y-shaped structure is configured such that each leg of the figure contains two, concentric pipe means. One pipe means institutes the exterior of the leg, and is translucent. The smaller pipe means is positioned inside the first, and a vacuum exists between the two. Water is permitted to enter the pipe means, via a further pipe means in communication with the source of the water. When the water rises in the legs of the apparatus, concentrated heat provided via, e.g., Fresnel lenses, acts to evaporate the water, resulting in separation of salt and impurities therefrom. Pure water condenses in the device and accumulates in a reservoir provided for this purpose.

Abstract:
Provided is a high efficiency electrode separation type water softening apparatus which softens a common water with a hard water characteristic in such a way to separate and remove a positive ion component using an ion exchange membrane, and converts most of a common water into a soft water in such a way to have a positive ion component be absorbed by a small amount of water flowing via the interior of an ion exchange membrane while extending a lot an exchange period of an ion exchange membrane, so it can be used for a long time. The electrode separate type water softening apparatus comprises a chamber which has a hollow inner space, a certain length and a positive electrode member, thus supplying an electric current (+) to its inner side; a negative electrode member 40 which is formed at the center of the chamber in a longitudinal direction of the chamber, with an electric current (−) being applied thereto; an ion exchange membrane which is disposed between the negative electrode member and the positive electrode member; a first input port and a second input port which separately input hard water into the inner side and the outer side of the ion exchange membrane, respectively; and a first discharge port which discharges the hard water inputted in response to the first input port and the second input port to the outside of the chamber and discharges a positive ion concentrated water C, and a second discharge port which discharges a soft water.
Abstract:
A method for recovering inert or living microparticles in which a rising liquid column is set up under negative pressure of an aqueous effluent that includes inert or living microparticles, and a foam is separated at the top of the column into a multiphase effluent enriched with inert or living microparticles relative to the aqueous effluent and into a mostly liquid effluent depleted of inert or living microparticles relative to the aqueous effluent. The invention also concerns the different applications of this method and an installation implementing this method.
Abstract:
A contact reaction tower, including: a central cylinder; and an outer cylinder. Lift pipes and a water inlet pipe(s) are installed in the central cylinder, reflux windows are formed on the wall of the central cylinder, and the water flow circulation between the central cylinder and the outer cylinder is realized through the lift pipes, the water inlet pipe(s), and the reflux windows, such that the water flow internal circulation of the whole contact reaction tower is realized. The contact reaction tower is sealed in its entirety from the outside environment, and a gas guide pipe is installed at the top of the contact reaction tower.
Abstract:
An electrolysis cell is provided, which includes an inlet, an outlet, and coaxial, cylindrical inner and outer electrodes. A cylindrical ion-selective membrane is located between the inner and outer electrodes and forms respective first and second electrolysis reaction chambers on opposing sides of the membrane. Fluid flow paths along the first and second chambers join together as a combined inlet flow path through the inlet and a combined outlet flow path through the outlet.
Abstract:
The invention relates to a device for breaking the electrical continuity of the stream of caustic soda produced in mercury-cathode chlor-alkali plants. The device is comprised of a vessel internally subdivided into three compartments by two flow-conveying septa, the three compartments being in communication and defining a caustic soda tortuous flow-path allowing the centrifugal deposition of mercury microdroplets released by the upstream amalgam decomposer.
Abstract:
The invention relates to a method and apparatus for removing impurities from waste water by electroflotation. The waste water to be cleaned is conducted through an electrolytic cell. Electrolysis is performed between two electrodes (1, 2) of different electronegativities, such that the more electronegative electrode (1), which is non-wearing in a cleaning process, is used for producing hydrogen gas and hydroxyl ions from water. The less electronegative electrode (2), which is an active, wearing electrode in a cleaning process, is used for producing metal ions in a solution to be cleaned. In addition to this basic reaction, a desired oxidation-reduction reaction is initiated in the cell in a strictly controlled electric field for removing one or more designated impurities from cleaned water.
