Since the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resin (softener) is generally used to displace Ca2+ and Mg2+ (the main component forming scale) in the water. With the increase of Ca2+ and Mg2+ in the resin, The efficiency of resin removal of Ca2+ and Mg2+ is gradually reduced.
When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to rinse the resin layer with the brine in the salt tank, and the hardness ions on the resin are replaced, and the resin is discharged with the recycled waste liquid. The softening exchange function is restored.
Raw water hardness: 3-10mg-N/L (1mg-N/L=2.8 German degree = 50mg/LCaCO3 hardness), such as raw water hardness higher than 10mg-N/L, increase one model or use secondary softening when selecting .
