Beschreibung
Your Job:
This EU-funded project is part of the international training network Bio-GENTLE, which will connect professionals of various backgrounds from academics and industry. A unique interdisciplinary approach combines fundamental analysis, experimentation, and mathematical modeling to create a flexible bioseparation platform. A cohort of 12 doctoral candidates will be trained and experience the complete chain from materials properties to process design and evaluation.
More information on the project can be found here:
This specific project (DC2) addresses preparative scale cross flow filtration devices, in which different membrane and spacer materials are stacked to achieve optimal retention and capacity. These stacks are arranged in cassettes with complex internal geometries to achieve high surface areas at low footprints. Non-homogeneous flow, local compression of the filter material and hydrodynamic bypasses are need to be analyzed and optimized. Special attention will be given to scalability of the filtration process and to the transferability of the findings between laboratory and production scales.
