Thin-film composite membrane on a compacted woven backing fabric for pressure assisted osmosis

• TFC membrane supported on backing fabric was fabricated for PAO process.
• RO and FO membrane casting methods were investigated.
• PAO membrane had a higher S value compared to FO membranes.
• PAO membrane had a higher water permeability compared to FO membranes.
• Developed PAO membrane can sustain applied hydraulic pressure.
