Separation (DSTI and NanoNextNl)

Within the separation theme, we work on the design of processes for fractionation of (food) components (completed work is by Janneke Kromkamp and Gerben Brans), and we approach this through experimental and computational studies (on scales ranging from the size of particles to the entire fractionation stack). This was also our approach in the finished work of Thanawit Kulrattanarak, who studied ratchets for separation of particles.

Current projects

  • The Shift project, which is part of DSTI, focuses on particle-particle interactions for enhanced separation options. Particles arrange in a liquid flow and this facilitates separation. Within the Shift team, Anna van Dinther,  Martijntje Vollebregt (supervised by Ruud van der Sman), Francisco Rossier and Norhan Nady join forces to investigate various aspects of this new separation technology. The work will be continued within the NanoNextNl initiative by Ivon Drijer, who will work on algae separation.
  • Design of a fractionation stack, based on particle behaviour is part of the project carried out by Solomon Bogale Kassa, who was awarded a sandwich Ph.D. grant by Wageningen University & Research.
  • Within the PhD project of Rianne Klaver we used particle behaviour in a different way. We try to capture specific particles on a the membrane, and in a later stage release them and separate them of.
  • Thomas Krebs has joined us as a post-doc to work on swirl induced coalescence of oil droplets in order to facilitate separation of emulsions. His project is financed through DSTI, and is a close collaboration with the physical and colloid chemistry group of Professor Martien Cohen Stuart).
  • Bram Sperber is also a joint post-doc with the PCC group, and he uses magnetic particles to facilitate separations.
