Demineralisation process involves removal of minerals by means of Ion Exchange Resins. Demineralization of water is achieved by passing water through Cation Resin Column and then though Anion Resin Column.
When minerals, which are salts of acid and base, dissolve in water, they get ionized in to Cations and Anions. Water demineralization thus is process of removing these Cation and Anions.
Aqua demineralization plants are mainly divided in to
a. Packaged Demineralisation Water Plants
b. Industrial Demineralised Water Plants
