What Is Lime Used for in Water Treatment? | Sciencing

Apr 24, 2017· Quicklime is made by heating calcium carbonate in a process called "calcining" to release carbon dioxide, leaving calcium oxide. Quicklime can be further processed by crushing and adding a small amount of water, to make hydrated lime, also called slaked lime, which is calcium hydroxide.

Water Treatment | Graymont

Softening - In water softening, hydrated lime is used to remove carbonate hardness from the water. Hardness caused by other calcium and magnesium salts, called noncarbonate hardness, is generally treated by means of the lime-soda process, which entails the precipitation of magnesium by lime. The co-produced calcium salt reacts with the soda ash to form a calcium-carbonate precipitate.
