Heavy Metal Removal from Aqueous Solutions using Zeolite Forward Osmosis Membrane

Abstract

In developing countries, naturally occurring heavy metals contaminate groundwater and are taken into the body as drinking water, resulting in health hazards. We proposed a forward osmosis process using zeolite membranes to remove heavy metals from water. Na–ZSM–5 membrane showed a small solute flux and a high rejection for As, Se and Cr.
