| Summary: | 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. |
