Modelling nanofiltration of electrolyte solutions
Advances in Colloid and Interface Science, 2019 This review critically examines current models for nanofiltration (NF) of electrolyte solutions. We start from linear irreversible thermodynamics, we derive a basic equation set for ion transfer in terms of gradients of ion electrochemical potentials and transmembrane volume flux.

Transport phenomena during nanofiltration of concentrated solutions [PDF]
, 2016 In most scientific studies on nanofiltration either the development of new membrane materials or the characterization of membranes is reported. In the latter case most studies use single solute salt or sugar solutions and/or investigate nanofiltration of

Preparation of PPSU Hollow Fiber Nanofiltration Membranes for Nanofiltration Application
Iraqi Journal of Chemical and Petroleum Engineering, 2017 PPSU hollow fiber nanofiltration membranes are prepared by applying two concentrations and various extrusion pressures according to the phase inversion method. Cross-sectional area and outer structures were characterized by using scanning electron microscope (SEM) and atomic force microscopy (AFM).
