Effect of Organoclay on the Performance of Reverse Osmosis Membrane
This study investigated the effect of Cloisite15A (C15A) organoclay in the substrate layer on the performance of reverse osmosis (RO) membranes. The substrate of the RO membranes was modified using different loading of C15A (ranging from 0.3 - 0.7 wt%) within polysulfone (PSf) substrate and the polyamide (PA) selective layer was formed on the top. Effect of the modified substrate layer on the w...
متن کاملThe Effect of Osmotic Dehydration on Reverse Osmosis Membrane Performance
Akin type (asymmetric) reverse osmosis membranes undergo an irreversible osmotic dehydration upon coming into contact (skin side) with salt solutions. The extent of consequent changes (in appearance; decrease in linear dimension, water flux and salt rejection) are dependent on the salt concentration. These observations are correlated with the expected morphological changes taking place duri...
متن کاملCharacterization and effect of biofouling on polyamide reverse osmosis and nanofiltration membrane surfaces.
Biofouling is a major reason for flux decline in the performance of membrane-based water and wastewater treatment plants. Initial biochemical characterization of biofilm formation potential and biofouling on two commercially available membrane surfaces from FilmTec Corporation were investigated without filtration in laboratory rotating disc reactor systems. These surfaces were polyamide aromati...

متن کاملInvestigation of the Effect of Copolymer Antiscalant on TDS Removal Efficiency in Reverse Osmosis Membrane
Background & objectives: Nowadays, according to membrane-based filtration processes; the use of substances such as antiscalants that prevents the formation of deposits during the treatment process, is very important from industrial point of view. This study aimed to synthesize styrene-maleic anhydride copolymer (PSMA) using the radical polymerization method and to investigate the factors and pa...
