|Abstract: ||This paper presents preliminary findings on the fluoride removal capability of some Ghanaian geomaterials
and their potentials of being used to develop, design replicable easy-to-manage rural community based
fluoride removal system. Batch experiments were performed on geomaterials (laterite and bauxite tailings)
with raw fluoride-contaminated water (10.31 mg/l) from a borehole to determine their potentiality of removing
excess fluoride from rural drinking water supplies. The raw bauxite tailings showed the higher removal
capacity. Further experiments were conducted using heat-treated bauxite tailings. The results indicate that
optimum fluoride removal is attained when the bauxite is heated to 600oC but removal capacity decreases
with increased heating temperature. XRF analyses to determine chemical composition indicated Al2O3, Fe2O3
and SiO2 (silica) to be the most dominant compounds in that order.|
