Abstract:
A first aqueous solution filled in an electrolytic cell (2) is electrolyzed by applying DC voltage between the electrodes 7a and 7b in said electrolytic cell 2, to form an oxidation field short of electrons in said aqueous solution; and then, a second aqueous solution with carboxylic acid dissolved in it is mixed into the first aqueous solution in oxidation field state, so that the first aqueous solution in oxidation field state obtains electrons and is deoxidized, and the carboxylic acid is oxidized, to produce carbonic acid gas in said aqueous solution. Therefore, the present invention can be used to produce carbonic acid gas solution at a low cost easily.
Abstract:
A system for producing high purity water, and particularly for the production of water that is suitable for injection, as well as method of using the same, are disclosed. The system includes a unique combination of known water purification methods that is particularly well-suited to the production USP purified water and USP water that is suitable for injection. The system minimizes potential for organism growth within the system by providing multiple means of organism destruction and removal and by not utilizing any standard water treatment media.
Abstract:
This invention, in addition to both more adequate disinfection effect and more adequate cleaning effect, offers a better electrolyzed alkaline water production unit and a better electrolyzed alkaline water production method in terms of storage stability before use or safety in comparison with strong alkaline solution.An alkaline water sterilizer 100 produces electrolyzed alkaline water by electrolyzing tap water which is neutral water by an electrolyzed alkaline water production unit 100a. Then, the electrolyzed alkaline water thus produced is electrolyzed by a hypochlorite water production unit 100b to produce hypochlorous acid by electrolysis and hypochlorite water having a pH value of at least 10 or more is produced as alkaline sterilizing water.

Abstract:
An electric deionized water production apparatus in which a direct current field is applied to a deionizing chamber packed with an ion-exchange material such that ions to be discharged are allowed to migrate in the direction identical or opposite to the direction of the water flow in the ion-exchange material, whereby ionic impurities adsorbed in the ion-exchange material are discharged from the system, the ion-exchange material being a mixture of a monolith-shaped organic porous ion-exchange material and ion-exchange resin particles. The electric deionized water production apparatus has a simple structure that can reduce material cost, process cost, and assembly cost, capable of accelerating migration of the adsorbed ionic impurities to facilitate discharge of the adsorbed ions and free from a deflected flow due to swelling or shrinkage accompanying an ion-exchanging reaction, and from poor contact with an ion-exchange membrane.
Abstract:
A treatment method of organic compounds included in waste water, comprising the steps of:supplying waste water to an adsorber 2 filled with an adsorbent 3 therein for adsorbing the organic compounds in the waste water by the adsorbent 3 in the adsorber 2, supplying a current between an anode 9 and a cathode 8 in water including an electrolyte in an electrolyzer 6 for electrolyzing the water including an electrolyte, and supplying an electrolyte resulting from electrolysis in the electrolyzer 6 to the adsorbent 3 in the adsorber 2 for contacting the electrolyte with the adsorbent 3, so that the organic compounds adsorbed by the adsorbent 3 are desorbed or decomposed.
Abstract:
An electronic water treatment apparatus includes an electronic impulse generator and control box attached to a power source. An impulse chamber includes a cylindrical anode rod inside a tubular cathode and is connected to the impulse generator and control box with a low-voltage cable which is no more than about six feet long. The impulse generator and control box supply about 16 v DC power and 120-180 milliamps to the impulse chamber at between 2300 and 5200 Hertz. The discharge frequency within the impulse chamber automatically varies with the conductivity of the aqueous solution within the impulse chamber. The impulse generator and control box supply power with a waveform that includes about a two microsecond break between each positive and negative pulse to prevent corrosion of the electrodes and create the aragonite form of calcium carbonate instead of the calcite form.

An impulse chamber includes a cylindrical anode rod inside a tubular cathode and is connected to the impulse generator and control box with a low-voltage cable which is no more than about six feet long. The impulse generator and control box supply about 16v DC power and 70 milliamps to the impulse chamber at between 2300 and 5200 Hertz.

Abstract:
An electrolytic water purification system and method use provides a water filtration device with a plurality of electrolytic cells having anodes and cathodes specifically selected to remove contaminants from water. The device is capable of efficiently removing nearly all contaminants from water and is also capable of purifying the water by destroying micro-organisms which are in the water. Many minerals are removed from the purified water, and it is not necessary to add chemicals to the water during or after the purification process.
