The ion exchange process percolates water through bead-like spherical resin materials (ion-exchange resins). Ions in the water are exchanged for other ions fixed to the beads. The two most common ion-exchange methods are softening and deionization.

   Softening is used primarily as a pretreatment method to reduce water hardness prior to reverse osmosis (RO) processing. The softeners contain beads that exchange two sodium ions for every calcium or magnesium ion removed from the "softened" water.

   Automatic Water Softener enhances the quality of water by replacing hard salt of magnesium & calcium with sodium. Its fully automatic micro processor controlled time based regeneration process gives you freedom from calling a technician time and again maintenance / recharging.
