  • What Is Lime Used for in Water Treatment? Sciencing

    Quicklime is made by heating calcium carbonate in a process called quot;calciningquot; 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.
