TLDR
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.About:

Humic acids coagulation: influence of divalent cations
TL;DR: In this article, the effects of ionic strength (maintained by LiCl, NaCl or KCl) and Ca2+ and Mg2+ concentration on the coagulation of purified humic acids (HA) was studied.

Photochemical modification of poly(ether sulfone) and sulfonated poly(sulfone) nanofiltration membranes for control of fouling by natural organic matter
TL;DR: In this paper, the authors showed that UV irradiation alone increased membrane hydrophilicity, interpreted in terms of either the contact angle, θ, or surface wettability (cos θ).

The role of foulant–foulant electrostatic interaction on limiting flux for RO and NF membranes during humic acid fouling—Theoretical basis, experimental evidence, and AFM interaction force measurement
TL;DR: Tang et al. as discussed by the authors investigated the dependence of limiting flux on intermolecular interaction between foulant molecules and showed that conditions enhancing foulant-deposited-foulant repulsion resulted in greater limiting flux values.

Effect of soil sorption and aquatic natural organic matter on the antibacterial activity of a fullerene water suspension
TL;DR: In this paper, the authors investigated the association of a C60 water suspension (nC6) with natural organic matter, present as a soil constituent or dissolved in the water column, and its effect on the antibacterial activity of nC60.

Critical flux concept for microfiltration fouling
TL;DR: The concept of critical flux is introduced in this article to identify the critical flux and the desirability of starting filtration operations at a low flux, where a flux below which a decline of flux with time does not occur.
