2、 Working principle of ion exchange softened water equipment:

Ion exchange softened water equipmentMainly to remove scaling ions such as calcium and magnesium from water. When raw water containing hardness (calcium and magnesium ions) passes through the resin layer inside the exchanger, the calcium and magnesium ions in the water are replaced by the sodium ions adsorbed by the resin. The resin adsorbs the calcium and magnesium ions, and the sodium ions enter the water. In this way, the water flowing out of the exchanger is softened water with hardness removed. Due to the fact that the hardness of water is mainly formed and represented by calcium and magnesium, it is generally usedcation exchange resin(Water softener), to remove water from the waterCa2+、Mg2+The main component that forms scale is displaced and carried out within the resinCa2+、Mg2+Increase, resin removalCa2+、Mg2+The efficiency gradually decreases. After the resin absorbs calcium and magnesium ions, it needs to be regenerated. The regeneration process is to rinse the resin layer with saline solution in the salt tank, replacing the hardness ions on the resin. The resin is then discharged from the tank with the regeneration waste liquid, and the softening exchange function is restored. Due to the fact that the hardness of water is mainly formed by calcium and magnesium, the principle of sodium ion exchange softening treatment is to pass the raw water through a sodium type cation exchange resin to remove the hardness components in the waterCa2+、Mg2+Compared to resinNa+Exchange to adsorb waterCa2+、Mg2+Soften the water. As forRNaRepresenting sodium type resin, its exchange process is as follows:

2RNa + Ca2+ = R2Ca + 2Na+

2RNa + Mg2+ = R2Mg + 2Na+

That is, water passes throughSodium ion exchangerAfterwards, in the waterCa+、Mg+Replaced byNa+.

3、 Working procedure of ion exchange softened water equipment:
1Water production (operation): Untreated water passes through the resin layer, undergoes exchange reaction, and produces soft water.
2Backwash: Water enters from the lower part of the resin layer, loosens the resin, and removes fine impurities.
3Salt regeneration: utilizing high concentration saltwater（NaCl）Flowing through the resin, the failed resin is restored to a usable sodium type resin.
4Rinse: According to the water supply process, rinse excess salt solution and regenerated calcium and magnesium ions through resin.

5Water replenishment: Inject water into the salt tank to dissolve the salt particles for the next regeneration.
