Abstract

This paper focuses on the performance of polysulfone (PSf) and polyethersulfone (PES) ultrafiltration membranes with polyethylene glycol (PEG). The flat sheet membranes were prepared via phase inversion method that casting dope solution consists of polysulfone (PSf) and polyethersulfone (PES) separately as polymer, while N-methyl-2-pyrrolidone (NMP) as solvent material. PEG 400 was used as a pore forming additive in the casting dope solution. The morphology of membranes was analyzed by scanning electron microscopy (SEM). The performance of membranes was evaluated in terms of pure water flux (PWF) and humic acid (HA) rejection. The effect of different concentration of PEG additive exhibits significant improved on PSf and PES membrane performance. The results indicated that PES ultrafiltration membrane exhibits good performance in PWF as compared to PSf membrane. It was found that the pure water flux increased as the PEG concentration increases (0 to 8 wt %) in casting solution. As a result, the morphology of membranes prepared with high concentration of PEG has larger pore size.
