Description
Summary:Defluoridation of water by the Nalgonda technique is a commonly used household process in areas of endemic fluorosis in villages around Nalgonda (Andhra Pradesh, India). The aim of this paper was to modify the existing well-known procedure minimally and without much change in the cost to bring about a greater removal of fluoride. By doubling the concentrations of alum and lime, water fluoride levels fell significantly (p< 0.001) in tap water and drinking water while pH levels and other inorganic factors remained unaffected.
