Polymer membranes with embedded nanoparticles that selectively remove ionic compounds (top) are employed in electrodialysis (bottom) to remove salt and metals, many of which are toxic, producing pure clean water and a non-toxic brine that is easier to dispose of. The green and red membranes can be flushed and reused many times, while valuable metals could potentially be salvaged.
