Heavy Metals Removed from Industrial Wastewater by Nanofiltration Membranes

The National University of Science and Technology MISIS along with researchers from Jain University and Sri Dharmasthala Manjunatheshwara College have been experimenting using nanofiltration membranes for the complete removal of toxic heavy metals from industrial wastewater.  Membrane technology is one of the most promising methods of purification.  The membrane works as an effective barrier for the zinc-modified aluminum oxide nanostructure removing 87% of arsenic and 98% of lead from the polluted water.  The scientists hope their research can be used for the treatment of industrial wastewater and large city water treatment plants.
