  • Patent number: 5057198
    Abstract: The invention relates to the field of water purification. A method for sening water by way of its electrochemical treatment involves causing water to pass in the form of two streams through anode and cathode chambers of a membrane electrolyzer. According to the invention, the water stream being fed to the anode chamber is preliminarily softened before supplying it to the anode chamber, and this stream is in the form of catholyte after the separation of precipitating hardness salts therefrom, anolyte being used as the end product. An electrolyzer for softening water has a casing divided by membranes into anode and cathode chambers, respectively.

  • Patent number: 5055170
    Abstract: An apparatus for setting the ion concentration in an ionic water generator which separates drink water between alkaline ionic water and an acidic ionic water by applying a DC voltage between electrodes in an electrolytic cell which are partitioned by an ion-exchange membrane apparatus comprises a device for measuring voltage drop at a portion leading to the electrolytic cell which is caused when a reference voltage is applied, and a calculator for calculating voltage Vx which is applied to the electrolytic cell to adjust ion concentration to a desired value from a proportion k of the voltage drop which is calculated by application of the reference voltage to water to be examined relative to the reference voltage drop caused by application of the reference voltage to reference water and a set voltage Vn which corresponds to the desired ion concentration on the basis of the following equation:Vx=k.times.Vn.

  • Patent number: 5043047
    Abstract: An aluminum smelting cell comprising a cathode having an active upper surface, a plurality of anodes each having a lower surface spaced from the upper surface of the cathode, said cathode upper surface being sloped at an acute angle in a primary or longitudinal direction of each anode, and being formed with pairs of oppositely sloped surfaces extending in a transverse or secondary direction under each anode to cause complementary shaping of the lower anode surfaces to reduce the migration of bubbles between the anode and cathode along the anode surfaces in said primary or longitudinal direction to thereby reduce the path length of said bubbles whereby the turbulence caused by coalesced bubble disengagement from the bath electrolyte is significantly reduced while maintaining adequate bath circulation between the anode and cathode.

  • Patent number: 5024749
    Abstract: The invention is both a system and method for continuously separating heavier from lighter isotopes of a particular element, such as zirconium. The system comprises a housing, a column assembly rotatably mounted with respect to the housing which includes a plurality of vertically oriented separation cells arranged in a circle, each of which contains a packing material, both a feed electrolyte source and a barren electrolyte source, each of which has an outlet mounted in the housing for continuously introducing either a feed electrolyte or a barren electrolyte into each of the cells as they rotate past the outlets, and upper and lower electrodes disposed over the upper and lower ends of the separation cells for inducing the electromigration of the lighter zirconium ions toward the lower ends of each of the separation cells. A drain assembly disposed beneath the column assembly continuously collects isotopic enriched electrolyte from the bottom ends of the separation cells.
