Abstract: A study was conducted to investigate performance of soils rich in bauxite and kaolinite in removing excessive fluoride from water samples collected from different natural water sources. Soil samples from the field were dried, crushed and sieved. Defluoridation processes were conducted in the laboratory using magnetic stirrers. Non-activated and activated soils rich in bauxite and kaolinite were used in this experiment. Results showed that soil rich in bauxite had higher capacity in defluoridation than that of kaolinite. Furthermore, activated soil had higher fluoride removal capacity than non-activated one for both two soils. It revealed thet defluoridation process is dependent on initial concentration, quantity of soil and contact time. The both activated soil have minimum turbidity of water and results into quick water settlement.
