Water softening system

Softening water equipment, as the name suggests, is a device that reduces the hardness of water, mainly removing calcium and magnesium ions from water. Simply put, it is a device that reduces the hardness of water. Its main functions are to remove calcium and magnesium ions from water, activate water quality, kill bacteria and algae, and prevent scaling and descaling. Softening equipment cannot reduce the total salt content in the water during the softening process. It is widely used in hot water boiler systems, heat exchange systems, industrial cooling systems, central air conditioning systems, and other water equipment systems.
