ZnO NPs, membrane fabrication, polymer percentage, coagulation temperature, antifouling


The development of nanoparticles-incorporated membranes is one of the recent techniques in improving membrane qualities in terms of fouling propensity. In this study, Zinc oxide (ZnO) has been selected as the nanoparticles to be embedded in membranes due to its excellent antifouling and antimicrobial properties. Several parameters such as polymer percentage and bath temperature were studied during the membrane fabrication process via phase inversion technique. The effects of each parameter towards the membrane structure and performance were significant in producing good membranes. When the polymer percentage increased from 16wt% to 20wt%, the permeability decreased from 6.9 to 3.9 L.m-2.hr-1.bar-1 and humic acid rejection increased from 78% to 95%. On the other hand, the coagulation temperature increment will lead to increment of permeability from 2 to 4 L.m-2.hr-1.bar-1 but gave rejection from 93% to 96% at 15oC to 25oC, and 86% at temperature of 35oC.In conclusion, the optimum condition for nanoparticles-incorporated membranes fabrication was shown at 20% of PSF at 25oC.
