Quicklime | Mississippi Lime

At Mississippi Lime, our calcium oxide (CaO), or commonly referred to as quicklime, is a high calcium content derivative of our 98.5% pure calcium carbonate (limestone). Calcium oxide is produced by heating calcium carbonate to 2000 degrees F where carbon dioxide disassociates as a gas from the calcium carbonate:

Advanced Water Treatment Concepts

Quicklime, (in pellet form), must first be slaked, or mixed with water then heated to turn it into hydrated lime before use. When quicklime is mixed with water there is a potential for explosions due to the heat released from the chemical combinations. Lime also has reactions with alum and ferric sulfates so direct mixing should be avoided.
