Demineralisation is the process of removing most of the mineral content from raw water. In general, demineralisation of water is carried by first passing water onto a Tulsion® cation exchanger in the hydrogen form, followed by Tulsion® anion exchanger in hydroxyl form, in two-column process. Cation exchange resin will replace the positively charged ions retaining H+ ions while anion exchange resin will replace the negatively charged ions retaining OH- ions. This combination will result in production of de-mineralised water.
