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.

Effect of fouling on removal of trace organic compounds by nanofiltration
Shima Hajibabania,Arne Verliefde,Arne Verliefde,Jörg E. Drewes,Long D. Nghiem,James A. McDonald,Stuart J. Khan,Pierre Le-Clech +7 more
TL;DR: In this article, the authors assess the impact of organic-based fouling layers on the removal of a large range of trace organics and find that fouling generally reduced the membrane surface charge; however, the alterations of the membrane hydrophobicity and surface roughness were dependent on the foulants compo- sition.
Removal of glycerol from enzymatically produced 2-α-d-glucosyl-glycerol by discontinuous diafiltration
Andreas Kruschitz,Bernd Nidetzky +1 more
TL;DR: Nanofiltration for the separation of glycerol from 2-GG is demonstrated and the purity of the product solution increased to 80%, which is comparable with commercially products containing functional carbohydrates.

Effects of hypochlorite exposure on morphology and trace organic contaminant rejection by NF/RO membranes
Alexander Simon,Long D. Nghiem +1 more
TL;DR: In this paper, the impacts of membrane degradation due to chlorine attack on the rejection of inorganic salts and trace organic contaminants by nanofiltration (NF) and reverse osmosis (RO) membranes were investigated.
Effect of coagulating agent viscosity on the kinetics of formation, morphology, and transport properties of cellulose nanofiltration membranes
TL;DR: In this paper, the influence of the viscosity of the medium on the formation of structure, morphology, and transport characteristics of the precipitated polymer is studied by example of forming of the cellulose membranes from solution in N-methyl-morpholine N-oxide using some proton-donor coagulants.

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.
