Ion Exchange Systems

An ion exchange system consists of a tank containing small beads of synthetic resin. The beads are treated to selectively adsorb either cations or anions and release (exchange) “counter-ions” based on the relative activity compared to the resin. This process of ion exchange will continue until all available exchange sites are filled, at which point the resin is exhausted and must be regenerated by suitable chemicals. Ion exchange systems are used in several ways.
