Abstract

Membrane technology is commonly used because it is one of the most effective and efficient technologies in producing clean water. The PSf-rGO / TiO2 UF (Ultra Filtration) membrane was synthesized using the phase inversion NIPS method. The membrane was synthesized by modifying the membrane surface by adding rGO / TiO2 nanoparticles to achieve the best performance. The membrane matrix used wasthe polymer of Polysulfone (PSf) with 0, 0.5, 1, and 1.5 wt% nanoparticles addition and UV irradiation time of 0.5, 1, 3, and 5 minutes. The higher concentration addition of rGO / TiO2 at 1.5% resulted in the best permeability. Meanwhile, the UV irradiation time of 3 and 5 minutes were the lowest time to gain permeability value.
