Water Softening is a technique to remove the ions, in most cases calcium and magnesium ions which are caused the hard water as well as iron ions. A natural water contains calcium and magnesium ions which form salts and less soluble strontium and barium cations that causes pipe clogging, and soap and detergent dissolving them in the water. The best way to soften water is to use a water softener unit which is usually achieved using lime softening or ion-exchange resins.
