Water Treatment Filter Media Function And Function - Softening Resin

Softening, which reduces the hardness of water. The softened water system consists of three parts, namely ion exchange part, salt regeneration part and control part. Ion exchange technology is the working principle of the softening system, its main body is ion exchange resin, because the hardness of water is mainly formed and expressed by calcium and magnesium, it is generally used cation exchange resin, the water Ca2+, Mg2+ (the main component of the formation of scale) replacement, with the increase of Ca2+ and Mg2+ in the resin, The removal efficiency of Ca2+ and Mg2+ by resin gradually decreased. Therefore, when the softening water equipment is used for a period of time, the regeneration part of 25% NaCl concentration is required to regenerate the resin, restore the efficiency of the resin and improve the service life of the resin. The control part can realize the automatic operation of the whole system, according to the operation time of the system or through the amount of water automatically salt regeneration.
