Are you driven by a passion to tackle the environmental challenges of the built environment using cutting-edge technology? Does the thought of contributing to sustainable wastewater treatment excite you? If so, this Engineering Doctorate (EngD) at the University of Twente, focusing on electrically driven membrane separation technologies to combat the rise of contaminant release in industrial wastewater, is calling your name! This two-year post-master’s degree is designed for technological designers who are ready to take on real-world challenges. Our programme combines an educational journey with a practical design project.

Aqueous waste streams (10 – 100 m³/h), contaminated with, e.g. micro/nanoplastics, organic solvents, and/or oxygen-containing molecules are nowadays produced in industry. Enabling water reuse is one of the prime sustainability targets. Reactive Electrochemical Membranes (REM), which rely on a combination of physical and chemical separations to convert wastewater organic contaminants into non-toxic compounds such as water and carbon dioxide offer an economically attractive solution for the treatment of large quantities of waste streams. In the NWO Perspectief project on Recovery and Circularity of Valuable Resources program (ReCoVR), our aim is the recovery of industrial wastewater by developing durable REMs.

THE MISSION OF THIS DESIGN PROJECT
With this project, we want to produce Reactive Electrochemical Membranes with well-designed porous structures on tubular supports having a minimum surface of 12 cm².

Your mission is to build on the existing sub-stochiometric titanium dioxide REM developed within the ReCoVR project, and take it a step further, by developing a simple and safe approach to producing tubular REM.

Next to that, the design of a prototype of tubular membrane housing adapted for electrochemical experiments will be required.

Your main goal is to empower stakeholders with useful insights into appropriate reactive electrochemical membrane synthesis procedures and a REM housing prototype to facilitate the transfer and deployment of such innovative membrane systems.

To this end, the successful candidate will tackle the following tasks:

1. Conduct a comprehensive literature review to identify the current synthesis routes for tubular-based reactive electrochemical membranes, their performances, and the current reactor design limitations.
2. Prepare tubular-based REM and characterize their microstructure.
3. Design and prototype a tubular cross-flow REM testing station.
4. Test the tubular-based REM produce and compare the performance with conventional ceramic membranes.
5. Test the effectiveness of the REM with real wastewater effluents as produced in the industry and refine its design based on operational feedback.
6. Envision the next step of the provided solution.

• You have, or will shortly, acquire a master's degree in the field of chemical engineering, material chemistry, or a closely related subject area.
• The ideal candidate will have some knowledge or interest in ceramic membrane synthesis and characterization, anodic oxidation, and water filtration tests.
• Affinity with standard in chemical, and physical analysis (e.g. XRD, Raman)
• Interest to gain experience with electrochemical setup and testing of electrochemical properties.
• Strong capacity for independent problem-solving, creative thinking, and the development of innovative solutions.
• Excellent communication skills, both written and verbal, are crucial, as is the ability to collaborate effectively with a diverse team of experts, stakeholders, and policymakers.

• A very challenging position for two years, with the flexibility to work (partially) from home.
• A tailor made post-master design programme that has an educational component (~50%) as well as a design project (~50%).
• A gross monthly salary of € 2.618,-per month.
• There are excellent benefits including a holiday allowance of 8% of the gross annual salary, an end-of-year bonus of 8.3%, and a solid pension scheme.
• A minimum of 232 leave hours in case of full-time employment based on a formal workweek of 38 hours. A full-time employment in practice means 40 hours a week, therefore resulting in 96 extra leave hours on an annual basis.
• Free access to sports facilities on campus.
• Excellent career support and courses for your professional and personal development.
• A family-friendly institution that offers parental leave (both paid and unpaid).

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 6 motivated Phd students, 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
