De-ionization is the removal or reduction of positive ions called cations and negative ions called anions from the water supply. High purity water from 1.0 to 18.3 mega ohms/cm and a silica level of .10 ppm to 0.01 ppm or lower can be produced. The cation resin is converted to the hydrogen form and exchanges positive ions for hydrogen. The Anion resin is converted to the hydroxyl form and exchanges the negative ions for hydroxyl.
Resins are designed specifically for De-ionizer applications regenerating with approximately 6.4 pounds of 100% of HCI per cubic foot for hydroxyl
