The Basics of How a Water Softener Works

1. Hard water passes though a control unit into the resin vessel.
2. Calcium and Magnesium constituents of water hardness are attached to the Sodium saturated resin beads usually sulphonated polystyrene.
3. This simultaneously releases Sodium ions and water hardness is
eliminated. The process is called ion exchange.
4. When the resin becomes saturated with Calcium and Magnesium it is recharged by passing a salt solution through the resin.
