Some knowledge about water softener system


The water softener system, as the name suggests, is a device that reduces water hardness. It mainly removes calcium and magnesium ions in the water. In the process of softening the water, the water softener system cannot reduce the total salt content in the water.

Since the hardness of water is mainly formed and represented by calcium and magnesium, cation exchange resin (water softener) is generally used to replace Ca2+ and Mg2+ (the main components of scale formation) in the water. With the increase of Ca2+ and Mg2+ in the resin, The resin removal efficiency of Ca2+, Mg2+ gradually decreased.

After 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 salt water in the salt tank to replace the hardness ions on the resin. The softening swap function has been restored.
