Several conventional methods are available for arsenic removal from the water system, and the most commonly applied technologies include coprecipitation with adsorption onto coagulated flocs and sorptive media, oxidation method, treatment with lime, membrane filter technique, and ion exchange process. In the oxidation method, the dissolved oxygen converts the mobile arsenite into the less mobile arsenate and dissolved ferrous into ferric ion lowered the arsenic concentration in groundwater (Ahmed 2001; Ayoob et al. 2007).
