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 ].
