Fulleck's softening water system consists of three parts: ion exchange section, salt regeneration section and control section. Fulleck's softening water system consists of three parts: ion exchange section, salt regeneration section and control section. Fulleck's softening water system consists of three parts: ion exchange section, salt regeneration section and control section. Ion exchange technology is the softening system's working principle, its main body is ion exchange resin, because the hardness of water is mainly formed by calcium, magnesium and expressed, so generally using cationic exchange resin, to replace the water's Ca2+, Mg2+ (forming the scale's main ingredients), with the resin's Ca2+, Mg2+ increase, the resin removal performance of Ca2+, Mg2+ gradually decreases.
