Institutional Water Softeners

The main purpose of a water softener is to remove the divalent cations usually of calcium and magnesium. When a sample of water contains more than 120 mg/liter of them then the water is classified as Hard Water.

Hard waters are unsuitable for many domestic and industrial purpose. In addition to formation of scales in pipelines, equipment, appliances, sanitary fittings etc, hard water at times has adverse effects on human skin and hair.

The body of a water softener is a tank filled with resin beads that are covered with sodium ions. As hard water passes through, the resin beads act like a magnet, attracting the calcium and magnesium ions, or hardness, in exchange for the sodium ions.

Eventually the resin beads become saturated with mineral ions and have to be "re-charged". This process is called regeneration.

During the regeneration process, a strong brine solution is flushed through the resin tank, bathing the resin beads in a stream of sodium ions which replace the accumulated calcium and magnesium ions.
