Boiling the water causes the precipitation of solid calcium carbonate or solid magnesium carbonate. This removes the calcium ions or magnesium ions from the water, and so removes the hardness. Therefore, hardness due to hydrogen carbonates is said to be temporary.

Lime treatment can remove CH caused by Ca and Mg and NCH caused by Mg.
Lime soda treatment can remove CH caused by Ca and Mg and NCH caused by Ca and Mg.
Ion exchange process can produce zero hardness water.
