Defluoridation in Ethiopia
This project, is led by NGO Amigos de Silva and a public research institution CSIC (Spanish National Research Council), aims to provide safe water to rural communities around the Rift Valley in Ethiopia by reducing the high fluoride levels currently present in the drinking water, to those below the limit of 1.5 mg/L stablished by the World Health Organization (WHO). To accomplish this objective, we will install an innovative water defluoridation system developed by a team of scientists from Addis Ababa University and CSIC in order to reduce the concentration of fluoride in the water in two specific locations around Ziway, and hence reduce the incidence of fluorosis among the two communities object of this action. This defluoridation system is based on the use of the abundant, commercial and cheap natural silicates known as zeolites, which are properly modified to adsorb fluoride present in water.
Chemistry in Ethiopia
Elimination of Fluoride from Drinking Water in the Rift Valley using Natural Zeolites and fluoride-rich ground waters are both usually associated to volcanic regions, and hence in this work we study natural zeolites as fluoride-adsorbents in order to develop a ...
