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 ...
In this study, the effect of transmembrane pressure (TMP) on flux decline and protein rejection due to concentration polarization and fouling (adsorption) resistances during ultrafiltration of reconstituted skimmilk was investigated. UF experiments were carried out using a pilot plant unit equipped with spiral wound module and polysulfonamide UF membrane. A three-stage experimental strategy bas...
A two-dimensional, particle-based biofilm model coupled with mass transport and computational fluid dynamics was developed to simulate autotrophic denitrification in a spiral-wound membrane biofilm reactor (MBfR), where hydrogen is supplied via hollow-fiber membrane fabric. The spiral-wound configuration consists of alternating layers of plastic spacer net and membrane fabric that create rows o...
Background and Objective: Arsenic (As) is a highly toxic metalloid found in ground and surface waters. Arsenic contamination in drinking water leads to harmful effects on human health. In this study, the efficacy of Reverse Osmosis (RO) membrane technology was evaluated for arsenic removal from drinking water. Materials and Methods: This experimental study was carried out on RO membrane spiral-...
