Selective recovery of valuable minerals from ‘waste’ streams such as wastewater represents an opportunity to enhance the sustainability of chemical processes. Membrane technology using ion-exchange membranes allows for transport of ions against bulk concentration gradients and for concentrating ions of interest.
Ion-exchange membranes, recovery, minerals, waste streams
We will investigate the selective ion-recovery using different membrane geometries, operating conditions, ion-mixture composition under various process configurations. The research carried out in this project will allow for more sustainable chemical processes through recycling of valuable ions currently lost in waste streams.
