What is Water Hardness?
Hard water is water that contains mineral salts such as bicarbonate compounds, calcium ions, magnesium, etc. Water hardness is of two types: permanent and temporary hardness is measured mainly on the basis of the two metals magnesium and calcium. In general, water hardening factors are cations.
Conclusion
Therefore, it should be noted that reducing the hardness of water, which includes the removal of calcium ions, magnesium ions, and some other metal cations in the water, causes the water to soften. As a result of this process, the resulting water is more compatible with detergents and increases the life of the piping system.
