Hydrated lime, also known as slaked lime or calcium hydroxide, is obtained when calcium oxide (CaO) is mixed with water to produce a highly alkaline suspension (pH 11–13). It has subsequently been observed that the effective treatment of wastewater may be achieved through exposure of excreta-borne pathogens to an alkaline environment, resulting in pathogen deactivation and destruction [ 20 , 21 ].

pH Adjustment/Coagulation - Hydrated lime is widely used to adjust the pH of water to prepare it for further treatment. Lime is also used to combat "red water" by neutralizing the acid water, thereby reducing corrosion of pipes and mains from acid waters. The corrosive waters contain excessive amounts of carbon dioxide (carbonic acid).
