Drawbacks of applying nanofiltration and how to avoid them: A review
837
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.

Physicochemical characterization of solute retention in solvent resistant nanofiltration: the effect of solute size, polarity, dipole moment, and solubility parameter.
Siavash Darvishmanesh,Johan Vanneste,Elena Tocci,Johannes C. Jansen,Franco Tasselli,Jan Degrève,Enrico Drioli,Bart Van der Bruggen +7 more
TL;DR: The retention of a similar series of azo dyes with approximately similar molar mass by four nanofiltration membranes was studied and a very good correlation has been observed for retention of dyes versus their dipole moment.

Influence of membrane surface properties on initial rate of colloidal fouling of reverse osmosis and nanofiltration membranes
TL;DR: In this article, the most influential membrane properties governing colloidal fouling rate of reverse osmosis (RO) and nanofiltration (NF) membranes were identified for physical surface morphology, surface chemical properties, surface zeta potential, and specific surface chemical structure.

Factors affecting the rejection of organic solutes during NF/RO treatment—a literature review
TL;DR: Findings of a comprehensive literature review are reported, targeting membrane rejection mechanisms and factors affecting rejection, and a rejection diagram was proposed, which qualitatively allows prediction of solute rejection if certain solute and membrane properties are known.

A review of pressure‐driven membrane processes in wastewater treatment and drinking water production
Bart Van der Bruggen,Carlo Vandecasteele,Tim Van Gestel,Tim Van Gestel,Wim Doyen,Roger Leysen +5 more
TL;DR: In pressure-driven membrane processes, a pressure exerted on the solution at one side of the membrane serves as a driving force to separate it into a permeate and a retentate as discussed by the authors.

TL;DR: The role of drinking-water nitrate exposure as a risk factor for specific cancers, reproductive outcomes, and other chronic health effects must be studied more thoroughly before changes to the regulatory level for nitrate in drinking water can be considered.
