Water softener

Water softeners, also known as water softeners, are devices that remove hardness from water by means of ion exchange. They usually consist of a tank containing cationic resin, a multiport control valve and an adjacent brine tank containing common salt. Water hardness is the cause of many problems such as scaling and pipe blockages, stains, scale, rough clothes after washing, frizzy hair and dry skin after bathing, etc. At an industrial level, boilers, cooling towers, heat exchangers and other equipment are severely damaged by scaling due to hardness. The following table shows the classification of water by the WQA (Water Quality Association). Principle of operation. Our softeners operate by means of ion exchange. Calcium, magnesium and other metal ions are retained with cationic resin and replaced by sodium. Once the sodium has been depleted, the resin is regenerated with brine (saturated sodium chloride solution), displacing the hardness to the drain and recharging the resin with sodium. Technologies Standard softeners: assembled with standard quality food grade cationic gel resin. They are designed to work with high efficiency in salt consumption. They achieve an operating capacity of 20,000 grains of hardness per square foot, consuming only 2.5 kg (5.5 lbs) of salt. In practical terms we can consider that they remove 518 g of hardness for each kg of salt consumed.
