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:

Modelling the critical roles of zeta potential and contact angle on colloidal fouling with a coupled XDLVO - collision attachment approach
Junxia Liu,Yaqian Fan,Yuhui Sun,Zhihong Wang,Dongsheng Zhao,Tian Li,Bingzhi Dong,Chuyang Y. Tang +7 more
TL;DR: In this article, a coupled XDLVO-collision attachment (CA) model is proposed to quantitatively evaluate the critical roles of zeta potential ζ and contact angle θ of foulant on colloidal fouling.

Evaluating the impact of pretreatment processes on fouling of reverse osmosis membrane by secondary wastewater
TL;DR: In this article, the effect of two different pretreatments for secondary effluent (BCMF - biofiltration, coagulation and microfiber filtration) vs. ultra-filtration (UF) were evaluated for their effect in reducing the fouling potential of the effluent as expressed by the indices of BOD (biofouling), TOC (organic and biofOUling), and MFI0.45 (colloidal fouling).

Performance of thin-film composite hollow fiber nanofiltration for the removal of dissolved Mn, Fe and NOM from domestic groundwater supplies.
TL;DR: The main objective of this investigation was to assess the potential application of novel outside-in sulfonated polyethersulfone thin-film composite hollow fiber nanofiltration (HFNF) membranes to remove dissolved Mn, Fe and natural organic matter from domestic GW supplies.

Effect of solution chemistry on the surface property of reverse osmosis membranes under seawater conditions
TL;DR: In this paper, three aromatic polyamide thin-fi lm composite (TFC) RO membranes were characterized for chemical and physical properties under both low and high TDS conditions to see how these surface characteristics are aff ected by seawater-level TDS.

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.
