    Abstract: Electrodeionization methods and apparatus wherein ion exchange membranes are not utilized. Instead, ion exchange materials such as beads, fibers, etc., are disposed in alternating layers of anion exchange (AIX) materials and cation exchange (CIX) materials between opposite polarity electrodes. In a regeneration stage, a current is applied across the electrodes with water splitting occurring along at least one of the interfacial areas between neighboring AIX and CIX materials. The H+ and OH− ions formed via water splitting migrate in response to the electrical current and displace the salt ions in the respective AIX and CIX. The stack is flushed during the regeneration stage to remove the concentrated salt solution. During a deionization phase, the electrical current is terminated with influent fed to the stack for deionization. The salt ions in the influent are depleted via ion exchange as the influent contacts the AIX and CIX.

    Abstract: The present invention provides a multiple bed-type condensate demineralization method and apparatus for the method that are able to provide an improved treated water quality in ammonia operation by substantially reducing the cross contamination ratio during resin regeneration from the current cross contamination ratio. In the method of condensate demineralization using ion-exchange resin in a multiple-bed regime, condensate is passed through a resin layer having a multiple-bed structure in which an anion resin layer and a layer of a uniform particle size strong acid gel-type cation resin with a 10% to 16% degree of crosslinking, divided by a partition in such a manner that they do not mix with each other, are combined in alternation. The uniform particle size strong acid gel-type cation resin with a 10% to 16% degree of crosslinking is an ion-exchange resin that has a uniform particle size of 500 to 800 μm for which at least 95% of the resin particles fall in the range defined by the average particle size ±100 μm and the uniformity coefficient is less than or equal to 1.2. Ion-exchange resin that has come to require chemical regeneration is separately withdrawn and subjected to chemical regeneration by type and is returned into the originating partition.
