TECHNOLOGY: Ion-Exchange

What is Demeneralisation?

Demineralisation/deionisation is the process of removing all the dissolved substances ( Cations & Anions ) from water. In demineralisation, the cation resins release Hydrogen (H+) Ions in exchange for positively charged cations such as calcium, magnesium and sodium. anion resins release Hydroxyl (OH-) Ions in exchange for negatively charged Anions such as Chloride, Sulphate and Bicarbonate. The displace H+ and OH- combine to form H20.
