The effect of zinc oxide in the presence of polyethylene glycol (ZnO-PEG) nanoparticles in MPR under different membranes was studied in order to investigate the interaction of photocatalyst towards the degradation of industrial dye wastewater. The results revealed that ZnO-PEG nanoparticles and UF-PPA membrane are a great approach in MPR and produced good permeate quality in terms of SDWW degradation (100%), turbidity removal (100%), COD reduction (97.37 ± 0.06%) and electrical conductivity removal (92.38 ± 0.66%). Field Emission Scanning Electron Microscopy (FESEM) observation and contact angle analysis result confirmed that the presence of ZnO-PEG nanoparticles and UF-PPA membrane have great potential to improve fouling mitigation from being occurred in MPR. Hence, this research contributed a positive impact on the long-term use of water bodies and enhance the implementation of MPR for the industrial sector.
