Journal ArticleDOI
Characterisation of nanofiltration membranes for predictive purposes - use of salts, uncharged solutes and atomic force microscopy
TL;DR: In this article, an asymmetric nanofiltration membrane (Hoechst, PES5) has been characterised by three different techniques: modelling of the rejection of simple salts, modelling of rejection of uncharged solutes and atomic force microscopy.
Journal ArticleDOI
Modelling the performance of membrane nanofiltration - critical assessment and model development
TL;DR: A two-parameter model (pore radius and membrane charge) for electrolyte rejection has been developed that includes dielectric exclusion in the form of an energy barrier to ion partitioning into the pores that confirms that uncharged solute rejection in nanofiltration membranes may be well-described by such a continuum model.
Journal ArticleDOI
Characterisation and prediction of separation performance of nanofiltration membranes
W. Richard Bowen,Hilmi Mukhtar +1 more
TL;DR: In this article, the rejection of single electrolytes at six nanofiltration membranes has been experimentally studied using a model based on the extended Nernst-Planck equation, which accounts for the hindered nature of transport in the membranes.
Journal ArticleDOI
Modelling the retention of ionic components for different nanofiltration membranes
TL;DR: The analysis of the retention of ionic components was analyzed by the Donnan-steric partitioning pore model (DSPM), which showed that the charge density is not constant but depends very much on the salt and its concentration.
Journal ArticleDOI
Theoretical descriptions of membrane filtration of colloids and fine particles: An assessment and review
W. Richard Bowen,Frank Jenner +1 more
TL;DR: In this paper, a number of seminal approaches in this field have been proposed, based on the rate limiting effects of the concentration polarisation of the separated colloids at the membrane surface.
