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:

Identification of nanofiltration membrane foulants
TL;DR: Pilot-scale filtration experiments were performed to determine the effects of natural organic matter (NOM) character and ozonation on NF membrane fouling under constant operating conditions, indicating a high fouling potential by NOM associated with spring samples.

Ultrafiltration of protein and humic substances: effect of solution chemistry on fouling and flux decline
TL;DR: In this article, the rate and extent of adsorption of a protein and a humic acid onto membranes were measured at varying conditions of pH and ionic strength, and the resistance-in-series approach was used to calculate reversible and irreversible fouling resistances, which were then compared for static and dynamic runs in order to determine the effect of convective flow and electrostatic interactions on fouling behavior.

Cleaning results of new and fouled nanofiltration membrane characterized by zeta potential and permeability
TL;DR: In this paper, the results of the zeta potential measurements with and without chemical cleaning of virgin and fouled membrane provided by GE Osmonics (DK, HL and DL), as well as fouled DK membranes were used in this study.

Composite reverse osmosis and nanofiltration membranes
TL;DR: A review of the field of thin film composite reverse osmosis membranes, with emphasis on the chemistry and composition of these membranes, is given in this article, with particular attention given to composite membranes that have found commercial use, whether in the present or past.
Journal ArticleDOI
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.
