Calcium oxide Wikipedia

Preparation. Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above 825 °C (1,517 °F), a process called calcination or limeburning,...

What Is Lime Used for in Water Treatment? | Sciencing

Apr 24, 2017· Lime in Municipal Sewage Treatment. As with water softening, lime raises the pH of sewage water containing phosphorus and nitrogen from organic sources, which can cause algae blooms. In the highpH environment, lime combines with phosphorus to create calcium phosphates, which precipitate out of the water as a solid.
