This paper examines the use of granular ferric hydroxide to remove both arsenate and arsenite present in drinking water by conduction batch and column studies. Batch and column studies showed that granular ferric hydroxide (GFH) could be effectively used in small water utilities to achieve less than 5 μg As/l in drinking water.
