I. Overview of softened water equipment Since the hardness of water is mainly formed and expressed by calcium and magnesium, a cation exchange resin (water softener) is generally used to displace Ca2+ and Mg2+ (the main component forming scale) in the water, and as the Ca2+ and Mg2+ in the resin increase, The efficiency of resin removal of Ca2+ and Mg2+ is gradually reduced. Mainly in addition to calcium and magnesium ions in the sputum water, the softened water equipment can not reduce the total salt content in the water during the process of softening water, and can be used for the softening of the makeup water of the air conditioning system and the treatment of domestic water. Second, the working principle of softened water equipment The fully automatic sodium ion exchanger uses the principle of ion exchange to remove scale ions such as calcium and magnesium in water. When the raw water containing hardness ions passes through the resin layer in the exchanger, the calcium and magnesium ions in the water are replaced with the sodium ions adsorbed by the resin, and the resin adsorbs calcium and magnesium ions and the sodium ions enter the water, so that the water flows out of the exchanger. Water is the softened water from which the hardness is removed. Third, the application of softened water equipment About the location selection of soft water equipment: The water softener must be placed on a firm horizontal surface. The distance from the drain should be short. The heat source such as boiler must be more than 3 meters. It is absolutely forbidden to approach acidic liquid or gas. Additional water treatment equipment (filters, deaerators) should be reserved. It can be widely used in the softening of make-up water in steam boilers, hot water boilers, exchangers, evaporative condensers, air conditioners, direct combustion engines and other systems. It can also be used in the treatment of domestic water such as hotels, restaurants, office buildings, apartments, homes, and softened water treatment in food, beverage, brewing, laundry, printing and dyeing, chemical, pharmaceutical and other industries.
