Water treatment RO plant & softener resin (water softening resin) there's two basic varieties of resin cation-exchange and anion-exchange resin. The following ions are generally observed in hard water- Cations
Calcium(Ca2+)
Magnesium (Mg2+)
Sodium (Na+)
Potassium (K+)
Anions
Chloride (Cl-)
Bicarbonate (HCO3)
Nitrate (N032-)
Carbonate (cO32-)
Principal raw water is passed via two small polystyrenes natural process resin (bead-filled) beds. While the cations get exchanged with hydrogen ions within the first bed, the anions are exchanged with hydroxyl ions, within the other.
