      abstract     = {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.
