1、 System principle

　　 Due to the fact that the hardness of water is mainly composed of calcium and magnesium ions in the water, it is necessary to use a softened water resin to adsorb the calcium and magnesium ions in the water onto the resin, thereby removing them from the water and obtaining soft water. When the softened water resin absorbs a certain amount of calcium and magnesium ions, its adsorption capacity will decrease. At this point, resin regeneration treatment should be carried out. Regeneration treatment is to wash the resin with concentrated salt water to replace the calcium and magnesium ions in the resin, producing concentrated water for discharge. 　

2、 Process flow

During the water supply process, the raw water is pressurized and passed through a resin layer to undergo adsorption, producing soft water. The backwashing process involves injecting water under pressure from the bottom of the resin layer to remove foreign objects from the resin. During the backwashing process, concentrated salt water is pressurized through the resin layer to displace the calcium and magnesium ions in the resin and generate concentrated water for discharge.
