A mathematical model is proposed as a contribution to the modelling of the concentration polarization phenomenon occurring during increasing transmembrane pressure in membrane processes. The developed model is based on the extended Nernst–Planck equation (to describe the transport in membrane pores) and film theory equation (to describe the transfer mechanism in the polarization layer). It is characterized...
A novel protocol is developed to characterize nanofiltration (NF) and reverse osmosis (RO) membranes that employ the Spiegler–Kedem membrane-transport model based on irreversible thermodynamics coupled with a Film Theory description of the concentration polarization. The novel aspect of this characterization protocol is extracting the concentration polarization boundary-layer thickness as well the...
