Lime is used in conjunction with alum or iron salts for coagulating suspended solids in order to remove turbidity from water. It serves to maintain the proper pH for most satisfactory coagulation conditions. In some water-treatment plants, alum sludge is treated with lime to facilitate sludge thickening on pressure filters.

Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2).
