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.
