The hardness of water is mainly composed of cations: calcium (Ca2+ ), magnesium (Mg2+) ions. When the raw water containing hardness ions passes through the resin layer of the exchanger, the calcium and magnesium ions in the water are replaced with sodium ions in the resin, and the resin adsorbs the calcium and magnesium ions while the sodium ions enter the water, so that the water flowing out from the exchanger is the softened water with the hardness ions removed.

In the selection of pipeline material for reverse osmosis machine, internal and external issues should be considered. The internal is the corrosion of the pipeline by the water quality, and the external is the operating environment. The operating environment of the reverse osmosis machine determines the external corrosion of the pipeline. If the operating environment is good, the surface coating (such as paint or galvanizing, etc.) is generally used.
