Web30. nov 2024 · The permeate flux is linked to the particle concentration on the membrane wall using the Darcy–Starling expression invoking axially varying osmotic and trans-membrane pressures. Results are discussed for dispersions of hard spheres serving as a reference system and for solvent-permeable particles mimicking non-ionic microgels. WebThis type of filtration is typically selected for feeds containing a high proportion of small particle size solids (where the permeate is of most value) because solid material can …
