| Summary: | Textile wastewater contains high level of chemical oxygen demand (COD) and color concentration, and the release of this effluent can adversely affect ecosystem and water quality. Conventional ultrafiltration (UF) membrane incapable to treat small size pollutants (such as dyes and multivalent ions) from the wastewater. Previously, we had successfully fabricated tannin-modified metal–organic frameworks (Tannin-MIL), then incorporated it in the polyethersulfone (PES) polymer matrix. The modified membrane has more hydrophilic surface than unmodified PES surface, making it more resistant and less prone to be affected by fouling. Herein, this study aimed to explore the performance of ultrafiltration mixed matrix membrane for textile wastewater treatment. The novel Tannin-MIL/PES membrane possessed excellent rejection up to ∼ 100% total suspended solid (TSS), 96.46% (COD), 97.04% (color), 97.41% (turbidity) and 89.94% total dissolved solid (TDS), with permeability up to ∼ 190 L/m2.h.bar during filtration of textile wastewater, which is 9.31 times higher compared to the unmodified PES membrane. |
