Abstract: This report documents the final year project of a student from Nanyang Technological University. In this project, the author compared a charged polyelectrolyte and silver nanoparticle modified polysulfone forward osmosis membrane to an un-modified polysulfone forward osmosis membrane. The membranes were compared for their hydrophobicity via the contact angle test and were tested for their anti-bacterial efficiency. From the results and observations obtained from this series of tests, it was noted that a charged polyelectrolyte can increase a membrane’s hydrophobicity. There was a 10% decrease in contact angle. It was also noted that silver nanoparticles do indeed have anti- bacterial properties, and thus can reduce bio-fouling in forward osmosis membranes.
