An experimental study was carried out to investigate the effect of polyphenylsulfone (PPSU) as the support polymer on performance of polyamide (PA) thin film composite (TFC) nanofiltration (NF) membrane. The microporous PPSU support membrane was prepared via non-solvent induced phase separation process. PA/PPSU membrane was fabricated by the interfacial polymerization of m-phenylenediamine (MPD) and trimesoyl chloride (TMC) on PPSU support membrane. The as-prepared TFC and PPSU support membranes were characterized by scanning electron microscopy (SEM). Pure water flux (PWF) of support membrane was determined. The PWF of 225 l/m2.h depicted that the as-prepared PPSU support membrane is in the range of UF membrane. The TFC membrane performance is evaluated through desalination of MgSO4 and NaCl solutions (2000 ppm). The PWF of this membrane was around 20 l/m2.h at 8bar and 25 ◦C. In addition, the rejection of MgSO4 and NaCl were almost 98% and 95%, respectively. The obtained results revealed that the prepared TFC (PA/PPSU) membrane has potential in application of reverse osmosis (RO) and NF processes.
