PhD position on the Engineering of hybrid ceramic membranes for the concentration of saline streams by electrodialysis


Closing in 6 days

Due to climate change, process water is becoming increasingly scarce, while (waste) salt solutions containing water and valuable salts are often discharged. Although technical solutions for the recovery of water and salts are available, these technologies are not cost-effective and sustainable. To secure industrial water availability and at the same time make optimal use of salt and water from waste streams, more energy-efficient and cost-effective technologies need to be developed.

Electrodialysis membranes offer an economically attractive solution for the treatment of these wastewater streams. Electrodialysis relies 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 is passed through the flow channels, cations and anions selectively pass through alternating cation- and anion-exchange membranes, respectively, thereby 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.

In one of the Phd projects, part of the granted 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.

    About the department

    Research in the Inorganic Membrane (IM) group encompasses macro- as well as micro-scale phenomena, in the field of ceramic/inorganic membrane technology, transport phenomena, and membrane process design. Within IM, you will join the Nanostructured Porous Membranes team composed of highly motivated researchers all working on the engineering of porous membranes with nanoscale features for challenging and demanding separations. Our goal is to develop the next generation of nanostructured porous hybrid membranes which will push further the combination of nanomaterials and polymer surface-modification science.

    About the organisation

    The Faculty of Science & Technology (Technische Natuurwetenschappen, TNW) engages some 700 staff members and 2000 students in education and research on the cutting edge of chemical technology, applied physics and biomedical technology. Our fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine. As part of a people-first tech university that aims to shape society, individuals and connections, our faculty works together intensively with industrial partners and researchers in the Netherlands and abroad, and conducts extensive research for external commissioning parties and funders. Our research has a high profile both in the Netherlands and internationally and is strengthened by the many young researchers working on innovative projects with as doctoral candidates and post-docs. It has been accommodated in three multidisciplinary UT research institutes: Mesa+ Institute, TechMed Centre and Digital Society Institute.
