Journal ArticleDOI
Effects of surface modification on antifouling and performance properties of reverse osmosis membranes
TL;DR: In this paper, the effects of surface modification of commercial reverse osmosis polyamide membranes were studied in terms of flux/rejection and surface properties, and the results showed that the modified polyamide polyamide showed better resistance to fouling by hydrophobic foulants.
Journal ArticleDOI
Chemical cleaning of UF membranes fouled by BSA
TL;DR: In this paper, the effect of chemical cleaning on the surface of MF and UF membranes was investigated using various cleaning agents and their concentration, time of clean-in-place treatment and frequency of cleanings.
Journal ArticleDOI
Modification of NF membrane properties by in situ redox initiated graft polymerization with hydrophilic monomers
TL;DR: In this paper, a modification of NF membranes (NF70, NF270) by HEMA lead to significantly reduced salt passage, especially of monovalent anions (chloride), and the effects of modification on solute retention were much more pronounced on the tertiary effluent.
Journal ArticleDOI
Surface properties and reduced biofouling of graft-copolymers that possess oppositely charged groups.

TL;DR: The hydration and swelling of the grafted polymer layer are shown to repel EPS and reduce their adsorption, which may lead to the design of novel antifouling surfaces.
Journal ArticleDOI
Characterization of novel acid-stable NF membranes before and after exposure to acid using ATR-FTIR, TEM and AFM
TL;DR: In this article, the structural and morphological characteristics of composite asymmetric membranes are analyzed in terms of the swelling, morphology and water vapor sorption, and the results suggest that both generation of hydrophilic groups and decreasing cross-linking are responsible for increased swelling.
