Deionization is a process done when there is an immediate need of purified water distribution. It is imperative that deionization is performed when the water is close to being utilized since extremely high water purity degrades quickly.

Deionization systems work by replacing negative and positive molecules in the water with hydrogen (positive) and hydroxyl (negative) molecules. In effect, organic substances are removed through filtration which improves the quality of the water and prevents the formation of scale deposits forming. For this reason, deionized water is one of the most preferred options of use in factories and manufacturing facilities.
