Limestone is a cheaper alternative for such applications. A case study showed that limestone can be used effectively to replace lime for the neutralization of arsenic rich acid water. The cost of limestone treatment is 45.8% less than that of lime. The acidity can be removed from 33.5 to 0.06 g/L (as CaCO3). The study also showed no significant differences in the TCLP characteristics of the resultant sludge when water is treated with lime or with limestone.
