Nanofiltration membranes review: Recent advances and future prospects
Abdul Wahab Mohammad,Yeit Haan Teow,Wei Lun Ang,Ying Tao Chung,Darren L. Oatley-Radcliffe,Nidal Hilal,Nidal Hilal +6 more
TL;DR: Nanofiltration (NF) membranes have come a long way since it was first introduced during the late 80's as mentioned in this paper, and significant development has taken place in terms of the fundamental understanding of the transport mechanism in NF membranes, which has been translated into predictive modeling based on the modified extended Nernst-Planck equation.

Membrane-based technologies for lithium recovery from water lithium resources: A review
Xianhui Li,Xianhui Li,Yinghui Mo,Weihua Qing,Senlin Shao,Senlin Shao,Chuyang Y. Tang,Jianxin Li +7 more
TL;DR: A comprehensive review of the advantages and challenges of the current membrane-based technologies applied to the recovery of a water lithium resource is presented in this article, where the authors highlight that the combination of membrane processes (e.g., nanofiltration, selective electrodialysis, and membrane distillation crystallization) with a conventional lithium precipitation process will lead to higher performance efficiency and lower cost.

Effect of solution chemistry on the surface charge of polymeric reverse osmosis and nanofiltration membranes
TL;DR: In this paper, a streaming potential analyzer was used to investigate the effect of solution chemistry on the surface charge of four commercial reverse osmosis and nanofiltration membranes, and the curves of zeta potential versus solution pH for all membranes display a shape characteristic of amphoteric surfaces with acidic and basic functional groups.

Removal of pollutants from surface water and groundwater by nanofiltration: overview of possible applications in the drinking water industry.
TL;DR: An overview of the applications in the drinking water industry that have already been realised or that are suggested on the basis of lab-scale research, and the possibility of using NF for the removal of hardness, natural organic material, micropollutants, viruses and bacteria, salinity, nitrates, and arsenic are discussed.
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.

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.

Nanofiltration modeling: the role of dielectric exclusion in membrane characterization
Serena Bandini,Daniele Vezzani +1 more
TL;DR: In this paper, a general model called the Donnan steric pore model and dielectric exclusion (DSPMD) is presented, in which the hindered nature of diffusion and convection of the species inside the membrane is considered.
