Abstract
This article reviews different membrane processes for the removal of arsenic from groundwater. The source of arsenic and its toxic effects on human body are illustrated. Various membrane filtration processes like micro-filtration, nano-filtration, ultrafiltration and reverse osmosis are discussed. The materials used in different membrane techniques are highlighted towards the removal efficiency of arsenic from water. The influence of pH and coexisting ions on rejection efficiency towards the removal of arsenic of these different processes are studied. The constitution of membrane, rejection mechanism, merits and demerits of different membrane techniques and challenges involved therein are discussed. The future direction of research on membrane based technology is also highlighted in this review. [Keywords: Membrane process, Nanofiltration, Reverse osmosis, Water contamination, Arsenic removal, Adsorption capacity]
