In this method, the soluble calcium and magnesium salts in waer are chemically converted into insoluble compounds, by adding calculated amounts of lime Ca(OH)2 and soda Mg2CO3.
Calcium carbonate CaCO3 and magnesium hydroxide Mg(OH)2, so precipitated, are filtered off.
Following are the reactions that takes place in this process:
