EnviroFALK ion exchange process

The ion exchange process

Drinking water contains different salts in varying concentration. These salts consist of metal ions (cations) and an acid residue (anions). Special ion exchange resins are used to remove these cations and anions. A cation exchanger selectively binds the cations such as sodium ions, calcium ions and potassium ions, and releases H+ ions into the water. An anion exchanger selectively binds anions such as sulphate ions and chloride ions and releases OH- ions into the water. This process results in fully demineralised water – in other words almost entirely pure H2O. Once the ion exchange resins are depleted, they are regenerated in the EnviroFALK regeneration station.
