      abstract     = {We present a boundary layer approximation (BLA) method for
                      calculating the concentration-polarization (CP) layer and
                      dispersion flow in crossflow ultrafiltration with a
                      cylindrical membrane [1]. Results are discussed for various
                      feed dispersions of colloidal particles, namely hard
                      spheres, charge-stabilized particles [2], solvent-permeable
                      non-ionic microgels [3, 4], and deswelling ionic microgels
                      [5]. State-of-the-art methods are used for the gradient
                      diffusion coefficient and viscosity entering the calculation
                      of filtration profiles [3, 5]. We show that the BLA profiles
                      are in quantitative agreement with predictions by a
                      finite-element method [1]. The BLA results are compared with
                      predictions by a similarity solution [4]. The BLA method is
                      extended to conditions where a filter cake is formed at the
                      membrane, with permeate flux results presented for a
                      hard-sphere system [6].},
