Softening water equipment refers to machine equipment that reduces the hardness of water. The key is to remove calcium and aluminum ions from the water. Softening water equipment cannot reduce the total salinity of the water throughout the entire process of softening water. The principle of softening water equipment: Because the hardness of water is mainly produced and indicated by calcium and magnesium, positive ion exchange resin (softening water equipment) is generally used to replace Ca2+and Mg2+(key components that produce dirt) in the water. With the increase of Ca2+and Mg2+in the resin, the efficiency of removing Ca2+and Mg2+by the resin gradually decreases. After the resin digests and absorbs a certain amount of chlorite, it is necessary to carry out regeneration. The entire regeneration process involves cleaning the resin layer with salt water in the salt tank, replacing the strong positive ions on the resin, and discharging them out of the tank with the regeneration wastewater. The resin then repairs the softening exchange effect. Because the hardness of water is mainly produced by calcium and magnesium, and indicating that the hardness of water is mainly produced by calcium and magnesium, and indicating that the basic principle of potassium ion exchange softening solution is to exchange the strength components Ca2+and Mg2+in the water with Na+in the resin based on sodium type cation exchange resin, thereby adsorbing Ca2+and Mg2+in the water and softening the water.
