PROBLEM TO BE SOLVED: To provide an electrolysis cell capable of eliminating the need to provide a diaphragm for partitioning the cell into an anode chamber and a cathode chamber, in an electrolyzing apparatus for electrolyzing a salt solution or the like to provide acidic electrolyzed water having strong sterilizing effect and alkaline electrolyzed water having cleaning effect.

SOLUTION: In this electrolysis cell, in order to separate an anode 4 side liquid and a cathode 5 side liquid from each other and to obtain these mutually separated liquids, this electrolysis cell 1 is constructed so that two housing sections 2, 3 in which electrodes are respectively housed, communicate with each other through a liquid junction 16, mounted at a position below the lower end of the electrodes, to secure electric conductivity to the housing sections 2, 3 through the liquids, whereby alkaline electrolyzed water is produced on the cathode 5 side while an acidic electrolyzed solution is produced on the anode 4 side separately from and without mixing with the alkaline electrolyzed water on the cathode 5 side.

PROBLEM TO BE SOLVED: To provide a water treatment method using electrolysis capable of dealing with even such a case that the electric conductivity of water to be treated is changed due to concentration by concentration or the like and capable of performing electrolytic treatment even with respect to more than one kind of water to be treated using single power supply, a water treatment apparatus therefor and a power supply device for electrolysis.

SOLUTION: When water to be treated is modified by electrolysis (1), a plurality of waters 51-54 to be treated are electrolytically treated using the same power supply and an equal current is allowed to flow through a plurality of the waters 51-54 to be treated using a constant current control means 1 to treat the waters 51-54 to be treated with electrolysis. When impurities are captured from water to be treated by electrolysis (2), a current is allowed to flow through water to be treated using the constant current control means 1 to electrolytically treat water to be treated.

PROBLEM TO BE SOLVED: To sterilize and deodorize the interior of a preserving chamber at a lower cost without keeping the interior of the preserving chamber more highly humid than necessary, through using chlorine gas volatilized from acidic electrolysis water.

SOLUTION: A method for sterilization and deodorization comprises sterilization and deodorization by using acidic electrolysis water generated through the electrolysis of water to be treated. Chlorine gas volatilized from the acidic electrolysis water is used for the sterilization and deodorization. The duration time in which the chlorine gas is volatilized from the acidic electrolysis water is adjusted through adjusting the effective chlorine concentration of the acidic electrolysis water, the whole capacity thereof, or the volatilizing speed of the chlorine gas from the acidic electrolysis water. The volatilizing speed of the chlorine gas is adjusted through the adjustment of the contact area between the acidic electrolysis water and air.

A process and a device for the treatment of water, especially for removing therefrom a large variety of pollutants, especially organic, inorganic and biological pollutants through in situ generation of ozone. Ozone is economically produced (in situ) at a high concentration through the interaction of electrolytically produce oxygen and UV light having a wavelength of 189 nm. The device has a set of anode and cathode for electrolytically producing nascent oxygen that reacts with UV light at a wavelength of 189 nm to produce ozone in situ within a vessel where the polluted water is submitted to the combinative action of ozone and other oxidation reactions. The device also has a hydrocyclone or retention tank of removing cationic pollutants such as heavy metals, free radicals as well as undesirable electrolysis by-products such as nascent hydrogen through a secondary outlet. Oxidation by-products are subsequently removed from the exiting water stream by means of decantation, flocculation, coagulation or filtration.

An apparatus and method for performing electrolysis on materials such as water, thereby electrically separating the electrolyte into its elemental components. More specifically, according to a preferred aspect of the instant invention, there is provided an apparatus for splitting water into hydrogen and oxygen that uses a specially prepared cathode in conjunction with incident light energy to increase the efficiency of that process. A preferred embodiment of this apparatus uses the photo collector/cathode which comprises a thin layer of metal, preferably nickel, deposited by electroplating or a similar technique onto a conductive surface (e.g., a sheet of copper metal). During the electrolysis process, the cathode is irradiated with light, thereby reducing the amount of electrical energy necessary to separate a given quantity of electrolytic material

Water treatment involves delivering an instantaneous electric current to one or more pairs of activated electrodes immersed in the water, each of the pairs of electrodes comprising a sacrificial electrode operating predominantly as an anode and an inert electrode operating predominantly as a cathode. The sacrifical electrode, when as an anode, is able to provide dissolved ions to the water as current passes between the pairs of electrodes, to assist in treating the water. The polarity of the electrodes is periodically reversed to reduce electrode clogging. The amount of charge passed by the instantaneous electric current is indicative of the degree to which the water has been treated, and is used to control the treatment process
