Commercial Water Softener Water Treatment System remove hardness using an effective resin. The resin attracts hardness in the water and exchanges it with salt, which is regenerated periodically. As the resin accumulates more hardness, the system must be regenerated using a brine solution. This rinses away the hardness and replenishes salt on the surface of the resin. The softened water can then pass through an RO system to remove the salt without the risk of scaling.

The hardness of water is mainly composed of the cation: calcium (Ca2+), magnesium (Mg2+) ion. When the hardness of raw water containing the exchanger resin layer, the water calcium, magnesium ion is absorbed by resin and release of sodium ions at the same time, this exchanger outflow of water is to remove the hardness ions in softened water, when the resin absorption of calcium and magnesium ions reached a certain saturation, increase the hardness of the water. At this time water softener will according to a predetermined program automatic failure of the regeneration of the resin, by the resin,the resin failure to restore to a sodium type resin with high concentrations of sodium chloride solution (saline).
