TL;DR: In this paper, the authors present a new model which takes into account the simultaneous action of all fouling mechanisms and describes the experimental results successfully, in order to contribute to the understanding of fouling phenomena by organic matter and the efficiency of the backwashing technique, which is applied in practice to restore membrane flux.

TL;DR: In this article, a rather thorough discussion of pesticides rejection by membranes is provided, highlighting the prevailing mechanisms and main factors involved, and an outline is provided of outstanding issues, both at the scientific and technological level, which require further investigation.

TL;DR: In this paper, the evolution of membrane fouling by sodium alginate, a microbial polysaccharide, is studied in ultra-filtration, aiming at identifying the significance of distinct fouling mechanisms and their degree of reversibility by backwashing.

TL;DR: In this paper, the effect of both Reynolds (Re) and Schmidt (Sc) numbers on the Sherwood (Sh) number for narrow channels with spacers, closely simulating conditions of feed-side channels in spiral-wound modules was studied.

TL;DR: In this paper, a numerical and experimental study is presented, aimed at obtaining a better understanding of transport phenomena in spirally wound membrane elements, where feed flow spacers are used to enhance mass transport characteristics and mitigate fouling and concentration polarization phenomena.
