Abstract

Carbon nanotube (CNT)-polyamide (PA) thin-film nanocomposite (TFN) reverse osmosis (RO) membranes have been highlighted due to their high water permeability. We evaluated the surface properties, membrane performance and fouling behavior of CNT-PA TFN RO membranes. The CNT-PA TFN RO membranes showed ∼30% enhanced water flux, which resulted in a lower energy consumption. The smoother surface of the CNT-PA TFN RO membranes led to less membrane fouling, while its biofouling resistance was insignificant due to less positioned CNTs on the membrane surface. These results provide important insights into the factors optimizing CNT-PA TFN RO membranes as a high performance RO membrane.
