Fluoride is very found and common contaminant in ground water. Due to the excess contamination of fluoride in drinking water it cause of fluorosis. The World Health Organization (WHO) guidelines give the permissible limit of fluoride in drinking water is 1.5gm/l. There are various methods for elimination of fluoride as Electrocoagulation, Ion exchange, Membrane process, Adsorption etc. Adsorption is widely explored because of its simplicity and easy processing. There are using agro wastes orange peel charcoal which is impregnated by aluminium, for fluoride removal. This adsorbent efficiency studied at different parameters such as adsorbent dose, agitation time, pH, initial concentration of fluoride and temperature. The adsorption of fluoride from ground water with aluminium impregnated orange peels gives 96% fluoride leaching at pH 6.
