PhD Position in Sustainable Water Treatment through Electrodialysis

4 weken geleden


Enschede, Overijssel, Nederland University of Twente Voltijd

Due to climate change, the availability of process water is becoming increasingly scarce while waste salt solutions containing valuable salts are often discharged. To address this challenge, more energy-efficient and cost-effective technologies need to be developed.

Electrodialysis membranes offer an economically attractive solution for treating wastewater streams. These membranes rely on the application of an electric field across a stack of ion-exchange membranes to drive ions toward the oppositely charged electrode. As the feedwater passes through the flow channels, cations and anions selectively pass through alternating cation- and anion-exchange membranes, respectively, forming ion-concentrated and depleted solution streams on each side of the membrane.

To ensure high separation performance, anion and cation exchange membranes combining both rigid and defined pores as well as surface functional groups are required.

Our Research

In one of the PhD projects part of the TKI E&I Odysseus program, we aim to engineer hybrid ceramic membranes for the concentration of saline streams by electrodialysis. To develop such systems, you will combine the advantages of well-designed porous ceramic nanostructures with organic surface functional groups.

The PhD student in this project will be working within the Inorganic Membranes group part of the MESA+ Institute for Nanotechnology. The Odysseus project will allow many relevant collaborations within the faculty of science and technology of the University of Twente, as well as with several end-users who are partners in the project.
