For many applications like particle removal from process water in various industries such as semiconductor, pharmaceutical or food, ultrafiltration plays an important role. Currently, the quality of these small pore size membranes is usually graded by their mean pore size under the assumption of various removal mechanisms (sieving and rejection of particles at the membrane surface, interception, inertia, diffusion). However, the evolution of the deposition efficiency with particle size and load usually does not correlate well with sieving characteristics alone. Thus, new models need to be developed to get an in-depth understanding of nanoparticle deposition inside different membrane structures....
