    Abstract: A device for the deionization of incoming water is disclosed. The device includes a tank and a generally hollow distributor tube in the tank for ingress into and downward movement of unpurified water through the tank. An opening adjacent the bottom of the generally hollow distributor tube and near the bottom of the tank distributes the unpurified water out of the generally hollow distributor tube. A mixed bed of purifying resin is within the tank, and surrounds the generally hollow distributor tube. The unpurified water travels upwardly through the tank where it is deionized to a high purity water by the mixed bed of purifying resin, after egress from the opening. The deionized water passes through a distributor and a filter before leaving the tank through an outlet.

    Abstract: A method for removal of at least one contaminant from a liquid is described, wherein a first step in liquid is introduced into a first of a plurality of liquid treatment containers and brought into contact in a liquid-medium suspension with a first quantity of a solid contaminant recovery medium for removing the contaminant for a period of time sufficient to achieve a desired efficiency of recovery of the contaminant. The liquid is then cycled from the first liquid treatment container sequentially through each of the plurality of liquid treatment containers to a final liquid treatment container while contacting the liquid in each of the liquid treatment containers with additional quantities of the medium in liquid-medium suspension for periods of time sufficient to achieve the desired efficiency of recovery in each of the liquid treatment containers. At least a portion of the medium is cycled from the final liquid treatment container through the plurality of liquid treatment containers to the first liquid treatment container in a direction countercurrent to flow of the liquid so as to maintain essentially a constant medium concentration in each of the liquid treatment containers, with the medium being substantially separated from liquid prior to cycling from one container to another container. At least a portion of the medium is transferred from the first liquid treatment container into a medium recycling means, in which the medium is treated with a contaminant recovery liquid for regenerating the medium.

    Abstract: 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.

    Abstract: The invention relates to a process for internal regeneration of mixed bed filters in which, after the exhausted ion exchanger mass has been separated into the two components and these have been regenerated and washed out, the exchanger layer in the region of the cation exchanger/anion exchanger interface is selectively removed from the mixed bed filter, the cation exchanger remaining in the filter is mixed with the anion exchanger remaining in the filter for the new loading stage, the ion exchanger mass removed from the filter is added again, when the work cycle has ended, to the exhausted ion exchanger mass before or during the separation into cation exchanger and anion exchanger, and, after the separation, the loading stage is started again with the regeneration of the cation exchanger and anion exchanger; and also to a mixed bed filter for carrying out the process.
