摘要： The method for separating and transferring an ion-exchange resin 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.
