Deionization is an ion-exchange process in which water flows through resin beds
Deionization is an ion-exchange process in which water flows through resin beds. Synthetic, cation resin exchanges hydrogen ions (H ) for positive ions, and anion resin exchanges hydroxide ions (OH-) for negative ions.
Product water quality from separate-bed deionization systems is typically within the 1 megohm-cm range (approximately 1 part per million as CaC03).
Water quality from a mixed-bed system is much higher than a separate-bed system, with 18 megohm-cm (0.028 parts per million) possible. In mixed-bed deionization, cation and anion resin are mixed to produce many separate-bed, ion-exchange sites within the tank.
In many applications, separate-bed deionization units precede mixed-bed deionzers in order to extend the life of the mixed bed and maximize the output of high-purity water
