Years ago, the Ion Exchange Resin Technique was developed to improve the quality of water chemistry, to remove water-soluble minerals from water. Today, every appliance that we call Water Softening Equipment in every industrial facility is also an Ion Exchanger Calcium (CA) and magnesium (Mg) ions, which are present in water and are referred to as hardness, are removed from the water and replaced with sodium (Na) ion in the water NaClsalt. For water softening and purification both granule and tablet salts are produced in high purity food quality.
