    • A method for separating and transferring an ion-exchange resin having the lower specific gravity from an ion-exchange resin having the higher specific gravity in an ion-exchange resin separating tank that is indispensable to a pure or ultrapure water producing plant and which is packed with a mixed bed of ion-exchange resins having different specific gravities is disclosed.This method contains the following essential steps: (1) a first step in which the mixed resin bed is separated into two layers by backwashing and the greater part of the ion-exchange resin (SBR) having the lower specific gravity is transferred by means of a perforated sluicing pipe that is disposed below the interface between the separated resin layers and a resin transfer pipe that is disposed above said sluicing pipe; (2) a second step in which SBR that is left untransferred in the first step is separated to be situated above the layer of the ion-exchange resin (SAR) having the higher specific gravity; and (3) a third step in which sluicing water is introduced into the tank at high flow rate through the sluicing pipe so that the particles of SBR are lifted in the water in the freeboard above the resin layer, while pressurized water is introduced from the top of the tank so as to transfer the residual SBR through the resin transfer pipe.According to the process of the present invention, substantially complete separation and transfer of SBR can be accomplished by operations in a fully automatic and unattended way, with the volume of SAR being held constant at all times after the transfer of SBR. If the process is applied to the condensate demineralizing system in a PWR power plant which requires stricter control of water quality that a thermal power plant, the sequence of the second and third steps may be repeated after the third step so as to reduce the total level of residual SBR to 0.05% of the total anion resin and below.

    • 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.
