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.
