Harmen Zwijnenberg is researcher and since 1999 working for the European Membrane Institute on membrane and polymer transport related projects in close cooperation with industry.
In the past years he worked with several different membranes technologies with a focus on transport phenomena and process optimization. Within the group his expertise is often used on the field of bipolar membrane (BP) electrodialysis (ED) membrane development, the application of (BP)ED in f.i. harsh conditions (chlorination, organic solvents, extreme pH) and projects for the food or diary industry and side stream valorization. Next to this he worked on several projects with organic solvent nanofiltration including pilot design and construction and the more traditional ultra and nanofiltration for aqueous applications. Since about 10 years he also worked extensively on gasseparation and the fabrication/spinning and characterization of gasseparation hollow fiber membranes.
Currently, he is working part time for the EMI and part time following a PhD program on the recovery of nutrients using ionexchange membrane technology in the Membrane Technology and Engineering for Water Treatment group of prof. Walter van der Meer.
Before his work here: He studied chemical engineering and graduated in 1994 in the Membrane Technology Group at the UT with prof. Strathmann. After his graduation he worked 4 years in Wageningen at the Agrotechnological Research Institute on module design and membrane technologies like electrodialysis, organic solvent nanofiltration and catalytic membrane reactors.
