When the raw water containing hardness ions passes through the resin layer in the exchanger, the calcium and magnesium ions in the water are replaced by the sodium ions adsorbed by the resin. The resin adsorbs the calcium and magnesium ions, while the sodium ions enter the water. In this way, the water flowing out of the exchanger is softened water with hardness removed.
Multiple filter media can be selected to achieve different effects

Interception of larger particle impurities, effective removal of suspended organic matter, colloids, sediment in water, and reduction of water turbidity, mainly used for water quality with high sediment content.


Mainly used for adsorbing unusual colors and odors, reducing water turbidity, chromaticity, odors, residual chlorine, pesticide residues, etc., it can effectively improve the degree of water purification.
