abstract = {Membrane ultrafiltration is a pressure driven process where
Brownian particles, such as small colloids or nanoparticles,
are concentrated. This process is of high importance for the
separation and enrichment of protein and microgel
dispersions, where convective-diffusive particle transport
determines the permeate flux. The efficiency of the
separation process is thus strongly dependent on particle
hydrodynamic structure and boundary conditions, membrane
properties, and particle interactions. We calculate the
concentration polarization layer and the permeate flux at
different operating conditions for cross-flow
ultrafiltration of BSA proteins and for ionic and non-ionic
microgels. We show that the proper specification of the
concentration dependent dispersion transport properties and
the inclusion of microgel permeability have a significant
effect on the filtration behavior on concentrated systems.},
