The process used for removal of all dissolved salts from water is referred to asdeionization. Deionization requires the flow of water through two ion exchange materials in order to effect the removal of all salt content.

Deionization

The terms demineralization and deionization are used somewhat interchangeably by the industry. While the term demineralization is generally better understood, deionization is especially apt.

How are salts Removed from Water?

Ions are removed from water through a series of chemical reactions.These reactions take place as the water passes through ion exchangeresin beds. In the regenerated form, cation resin contains hydrogen (H+) ions on its surface which are exchanged for positively charged ions. Anion resin contains hydroxide (OH-) ions on its surface which are exchanged for negatively charged ions. The final product of these two exchanges, H+ and OH-, form water molecules.
