In this work the selectivity of crosslinked organic solvent stable PBI membranes is tuned by varying molar ratio two grafting agents: a long flexible polymer modifier (Elastamine RE-1-1000, 1000 g mol-1) and small molecule (2-methoxyethylamine, 75 mol-1). Grafting exclusively with chain provided membrane molecular weight cut-off (MWCO) 2000 mol-1 in acetonitrile. Increasing proportion reaction ...
OBJECTIVES: The performance of spiral-wound nanofiltration (NF) and ultrafiltration (UF) membranes was investigated in terms of natural organic matter (NOM) rejection and associated NOM fouling. The study objectives focused on • demonstrating the effects of both hydrophobic and electrostatic interactions between NOM components and the membrane surface • determining influential factors (water qu...
In this work, performance data from a small-scale reverse osmosis (RO) plant based on seawater FilmTec spiral wound RO membranes for different periods of operation are presented and analyzed. A prototype RO set-up with a 2,200 L/d capacity was installed and operated at Urla Bay which was located in Izmir, Turkey. This study typically investigates RO performance in terms ...
Recent research efforts in taking pressure retarded osmosis closer to commercialization have concentrated on the development of osmosis-specific membranes. The module design, other hand, has not attracted much attention, although need for designs was identified, when traditional desalination were proven unfeasible applications. This work introduces a novel, design. submerged-helical is low pack...
