Abstract

In this study, the nanofiltration materials having high selectivity, high filtration and mechanical resistance have been developed for the removal of organic contaminants in wastewater. Al2O3-NP membranes were modified with multi-walled carbon nanotube (MWCNT), polyacrylamide-MWCNT (PA-MWCNT) and polystyrene-MWCNT (PS-MWCNT) to provide better performance in the treatment of wastewater. The evaluation of the separation performance of the prepared membranes was carried out at 25 degrees C using a vacuum filtration unit. Congo red (CR) and methylene blue (MB) dyes were selected as model pollutants. The results showed that the flux value was higher in the unmodified membrane, and the Al2O3-NP membrane modified with MWCNT exhibited high removal efficiency among the modified membranes.
