AbstractThis paper exhibits the feasible alternatives for removal of arsenic and the improvement of safe drinking water supply in the arsenic contaminated areas. Laboratory studies were carried out for each alternative. Two methods were evaluated for removal of arsenic from potable drinking water in the present research work; Conventional flocculation with ferric salts (chloride, sulphate) followed by filtration and adsorption with different types of adsorbents (iron coated sand and alumina).Various parameters such as, flocculent dose, pH, flocculation time and filtration media were considered to find optimum conditions. In Coagulation-Flocculation technique ferric chloride with optimum dosage of 0.05 g/lit was found to be effective for removal of arsenic. Granular iron oxide coated alumina as adsorbent was observed to be a viable alternative for arsenic removal.
