Method & Evidence

AimTo investigate the impact of incorporating porous titanium dioxide (PTi) nanoparticles into ultrafiltration (UF) membranes on their performance and antifouling properties within a simulated osmosis membrane bioreactor (OsMBR) process.
MethodExperimental research and material characterization
ProcedurePorous titanium dioxide (PTi) powder was synthesized using hydrothermal and sol-gel methods. This PTi powder was then integrated as a filler into polysulfone (PSf) to fabricate nanocomposite ultrafiltration membranes. The synthesized nanoparticles and membranes were analyzed using techniques such as BET, TEM, XRD, AFM, FESEM, FTIR, and contact angle measurements. Membrane performance and antifouling properties were assessed using bovine serum albumin (BSA) in a simulated wastewater feed. The UF membranes were further tested in a forward osmosis (FO) system to evaluate the OsMBR process.
