TL;DR: In this article, the fouling and retention of four different nanofiltration membranes (NF40, NTR-7450, NM-7410 and NM-7250) were followed using different model substances, and it could be seen that multivalent salts were retained better than small organic substances.

TL;DR: In this article, a comparison between two different waste water treatments in order to optimize the reuse of water and the recovery of heavy metal ions (Zn, Se, As, Cd and Pb) was carried out in collaboration with Met-Mex Penoles, the world's fourth largest metallurgical complex and the largest producer of refined silver and metallic bismuth.

TL;DR: In this article, the authors characterised recovery of phenol from an aqueous solution using a hydrophobic polypropylene membrane contactor, and the effects of temperature and hydrodynamics on the overall mass transfer coefficient were determined.

TL;DR: In this article, the mass transfer correlations have been obtained for the past eight decades by the Wilson-plot method which has proved to be suitable for systems operating in steady-state conditions and where the only variable is the fluid velocity.

TL;DR: By tailoring the conditions for fractionation using optimal conditions, very good selectivities even for the same sizes of protein could be obtained.

TL;DR: It is evident from the literature survey articles that ion-exchange, adsorption and membrane filtration are the most frequently studied for the treatment of heavy metal wastewater.

TL;DR: In this paper, the role of chemical and physical interactions in natural organic matter (NOM) fouling of nanofiltration membranes is systematically investigated, and it is demonstrated that the rate of fouling is controlled by an interplay between permeation drag and electrostatic double layer repulsion.

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.

TL;DR: Development of formulations for protein drugs requiring high dosing may become challenging for solubility limited proteins and for the subcutaneous route with <1.5 mL allowable administration volume that requires >100 mg/mL protein concentrations.

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.
