Water softening system

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.

The hardness standard for the effluent of the softener is usually not more than 0.03mmol/L
This standard is established based on the national standard GB/T 18920-2002 "Classification and Requirements for Industrial Water Quality". Different industries and usage scenarios may have specific qualification standards, but generally speaking, softened water refers to water with a hardness below 17.1mg/L (calculated as 50mg/L based on CaCO3).
