Journal ArticleDOI
Surface characterization by FTIR-ATR spectroscopy of polyethersulfone membranes-unmodified, modified and protein fouled
TL;DR: In this article, a modified polyethersulfone (PES) ultrafiltration membrane was characterized by FTIR-ATR spectroscopy to detect chemical changes during modification.
Journal ArticleDOI
Surface modification of commercial composite polyamide reverse osmosis membranes
TL;DR: Radical grafting of two monomers, methacrylic acid and polyethylene glycolmethacrylate, onto commercial composite polyamide reverse osmosis membranes was performed and found that the membranes were surface modified without damage to their transport properties.
Journal ArticleDOI
Surface modification of commercial polyamide reverse osmosis membranes by radical grafting: An ATR‐FTIR study
S. Belfer,Y. Purinson,Ora Kedem +2 more
TL;DR: In this article, a new grafting procedure was developed for surface modification of commercial polyamide reverse osmosis membranes, which was successfully grafted from aqueous solutions under mild conditions.
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
Effect of surface modification in preventing fouling of commercial SWRO membranes at the Eilat seawater desalination pilot plant
TL;DR: In this article, surface modified SWRO membranes of the SWC2 type (Hydranautics) were surface modified with hydrophilic polymers formed by redox initiated grafting with vinyl monomers.
