How does a deionized water system work?

Deionized water systems work by removing impurities through a process of ion exchange.
The deionizer system contains beds of electrostatically charged beads. The beads are either positively charged cation beads or negatively charge anion beads.
As the water passes over the beads the impurities in the water are attracted to the oppositely charged beads, removing them from the water.
The output water will contain little or no impurities.
The beads will eventually become exhausted and no longer able to remove any further impurities. At this stage the deionizer cartridge will need replacing.
Industrial deionized water systems have process for automatically regenerating the beads.
