| 520 | _ | _ | |a We present a comprehensive study of cross-flow membrane ultrafiltration (UF) [1] of charge-stabilized aqueous suspensions [2] and globular protein solutions [3]. Charge-stabilized dispersions suspensions exhibit interesting static and dynamic behavior, reflected in properties such as the osmotic pressure, generalized sedimentation coefficient and viscosity. These properties are determined by electro-steric and electro-hydrodynamic interactions. We calculate the wavenumber-dependent diffusion function, sedimentation coefficient and viscosity at different salinities, in good agreement with experimental and simulation data. The predicted dispersion properties form an important ingredient to the modeling of the convective-diffusive transport in a filtration process. The efficiency of the separation process depends on hydrodynamic boundary conditions, membrane properties and possible fouling effects, and the particle interactions. We calculate the particle concentration polarization layer, permeate flux, and thresholds for the onset of membrane cake formation, for different operating conditions. Our theoretical results are compared with UF experiments on charged-silica particle suspensions [2] and protein solutions [3].References[1] R. Roa, E.K. Zholkovskiy and G.
