• Nanofiltration - an overview ScienceDirect Topics

    Endre Nagy, in Basic Equations of Mass Transport Through a Membrane Layer (Second Edition), 2019. Abstract. Nanofiltration is a relatively newly introduced pressure-driven filtration membrane process. During transport through the membrane, both diffusive and convective fluxes take place due to the porous type of membrane and the transmembrane pressure difference.
