Most and least tolerable chemical impurities in water are the hardness producing ions, calcium and magnesium in different concentrations. And they are responsible for the hard scale that deposits and builds up in boiler tubes, pipe lines, condensers jackets, circulating system, cooking utensils and other equipment contracted by hot water.
Softener is used primarily to produce Zero soft water by highly acidic cation exchanger, which removes calcium and magnesium ions. Which are dissolved hardness producing compounds in the water and are replaced by sodium ions?
