The chapter summarizes different aspects to be considered in order to understand and analyse fouling and concentration polarization of porous membranes. In a first part, the properties of fluids and membranes are described and order of magnitudes of fluxes and forces are given. Then, transport phenomena and interactions are listed, which play a role in the mechanisms at the flui/membrane interface. Then the modelling of these different phenomena is considered, and allows a comparison between limiting mechanisms to be proposed.
