How the water softener system works


Since the hardness of water is mainly formed by calcium and magnesium and indicates that the hardness of water is mainly formed by calcium and magnesium and indicates that the principle of sodium ion exchange softening treatment is to pass the raw water through the sodium cation exchange resin, the hardness components Ca2+, Mg2+ in the water and The Na+ in the resin is exchanged, so that Ca2+ and Mg2+ in the water are adsorbed, and the water is softened.

If RNa represents the sodium resin, its exchange process is as follows: 2RNa +Ca2+ = R2Ca + 2Na+ 2RNa + Mg2+ = R2Mg + 2Na+ That is, after the water passes through the sodium ion exchanger, the Ca+ and Mg+ in the water are replaced by Na+. The general operation process of the control valve is: operation, backwashing, salt absorption, slow washing, water replenishment in the salt tank, and positive washing.

The water softener system can be widely used in softening the make-up water of steam boilers, hot water boilers, exchangers, evaporative condensers, air conditioners, direct combustion engines and other systems. It can also be used for the treatment of domestic water such as hotels, restaurants, office buildings, apartments, and households, and for the treatment of softened water in food, beverage, winemaking, laundry, printing and dyeing, chemical, pharmaceutical and other industries.
