Hydrated lime (Ca(OH) 2) is also known as calcium hydroxide or slaked lime. Hydrated lime can be added to water as it is without requiring any special equipment, so it is a popular choice for small water treatment plants. In contrast, quicklime (CaO), also known as calcium oxide or unslaked lime, must be slaked before it is used. Slaking is the process of converting quicklime to hydrated lime …

The calcination of limestone in itself releases the same amount of carbon dioxide as calcium hydroxide will absorb, so this method is at best carbon neutral 21. In the production of metals, lime is injected into the waste gas stream to neutralize acids such as fluorides and chlorides prior to being released to atmosphere 22.

In the, lime-softening, process, the pH of the water being treated is raised sufficiently to precipitate calcium carbonate and, if necessary, magnesium hydroxide. The normal pH of water is between 6.5–8.5. In small systems,, lime softening, is typically practiced by adding hydrated lime to raw water to raise the pH to approximately 10.
