Change in membrane performance due to organic fouling in nanofiltration (NF)/reverse osmosis (RO) applications
TLDR
In this article, the effect of fouling by organics on rejection was observed for the removal of 36 neutral trace plastic additives, endocrine disruptors and other organic contaminants, and the dominant removal mechanism is dependent on solute type but largely involving sieving, diffusion and other membrane solute interaction by polymer.About:

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.

Drawbacks of applying nanofiltration and how to avoid them: A review
TL;DR: In this article, the authors identify six challenges for nanofiltration where solutions are still scarce: avoiding membrane fouling, and possibilities to remediate, improving the separation between solutes that can be achieved, further treatment of concentrates, chemical resistance and limited lifetime of membranes, insufficient rejection of pollutants in water treatment, and the need for modelling and simulation tools.

Influence of molecular size, polarity and charge on the retention of organic molecules by nanofiltration
TL;DR: In this article, the retention of a series of organic molecules by four nanofiltration membranes was studied, and a good correlation with retention was found for each of the size parameters: molecular weight, the Stokes diameter, the equivalent molar diameter and a diameter obtained with energy minimisation calculations.
