Utilization of PVC-Cu/Al۲O۳ nanocomposite membranes for removing ofhumic acid from wastewater

The synthesis of Cu/Al۲O۳ nanoparticles (NPs) was done by the sol-gel method. Next, NPs wereused for the fabrication of PVC-Cu/Al۲O۳ nanocomposite membranes. The quantities of NPs were ۰and ۱ wt. % of the solid phase. The aim of this study was to evaluate how PVC-Cu/Al۲O۳nanocomposite membrane can be used to remove humic acid (HA) from wastewater in submergedmembrane systems. Results revealed that the addition of ۱ wt.% NPs to PVC (PCA۱) led to higherhydrophilicity and porosity. Moreover, PCA۱ exhibited an increased number of pores, with largerpores present on the top surface and larger macro-voids on the cross-sectional surface. The PCA۱exhibited the highest flux recovery ratio (FRR) and highest rejection rate for HA, with values of۸۲.۶% and ۹۲.۶%, respectively. PCA۱ demonstrated the higher antifouling performance.
