Abstract: A device for purifying at least one fluid is provided. The device includes at least a first ion exchange column, an inlet line and an outlet line. The inlet line and the outlet line are associated with a cover part, the inlet line is connected to a first supply line into a first free space between a bottom part and at least one nozzle insert, which is formed as a first bottom nozzle insert, and the nozzle insert has a number of openings for the passage of the fluid. The openings are distributed over at least a partial surface of the nozzle insert, by which the fluid can be introduced into a first volume of the ion exchange column which can be filled with an ion exchange resin.

Abstract: A novel apparatus for an ion exchange system is provided. The apparatus comprises a first column for housing a first fluidized bed through which particles are flowed countercurrently to an ion-containing fluid to yield ion-loaded particles, a second column through which the ion-loaded particles are flowed countercurrently to an eluent fluid to yield regenerated particles, and a transport section which transfers the regenerated particles for re-introduction into the first column to repeat the ion exchange cycle in a continuous manner. A continuous method of ion exchange is also provided.
