dc.description.abstract Forward osmosis is a greener desalination process as compared to reverse osmosis, which is the most dominant desalination technology in the world. The most dominant membrane morphology used in forward osmosis is thin film composite (TFC) membranes. TFC membranes consist of a selective polyamide top layer and a support layer in the ultrafiltration range. The supports are composed of commercial polymers such as polysulfone (PSf), polyether sulfone (PES), polyimides (PI), polyamides (PA), and polyacrylonitrile (PAN). These commercial polymers are derived from fossil fuels. This research work aimed to replace the commercial polymers with recycled PET (polyethylene terephthalate), which is a sustainable alternative to commercial polymers and can be used to fabricate TFC membranes in a more sustainable way. The effects of varying evaporation time, reaction time and additives on the performance of TFC membranes were studied. The fabricated TFC membranes showed good performance during a forward osmosis process to desalinate water. They had a comparable selectivity to conventional TFC membranes made with polyether sulfone (PES) support. For 1 M NaCl draw solution, they exhibited a water flux of 10.6 LMH and a reverse salt flux of 4.2 gMH with a selectivity of 0.4 g/L. The performance of TFC membranes synthesized during the study needs further study to assess their performance during long term operation. en_US
