1. one kind is being used for the method that the deionized electrodeionization units of water suppresses incrustation scale formation, one side of described device is provided with the anolyte compartment, relative side at device is provided with cathode compartment, also alternately be provided with a plurality of dilution chamber and concentration compartments between described anolyte compartment and cathode compartment, described method comprises step:

  • Must deionized feed water by dilution chamber with preparation purifying current;

    Be used to accept from the ionic water of feed water or aqueous solution with the anti-direction of described feed water by at least one described concentration compartments;

    Water or aqueous solution are by anolyte compartment and cathode compartment;

    Between described anode and described negative electrode, apply voltage, thereby the ion in the feed water will migrate in the water or aqueous solution of concentration compartments.
