Developing a Thin Film Composite Membrane with Hydrophilic Sulfonated Substrate on Nonwoven Backing Fabric Support for Forward Osmosis

This study describes the fabrication of sulfonated polyethersulfone (SPES) as a super-hydrophilic substrate for developing a composite forward osmosis (FO) membrane on a nonwoven backing fabric support. SPES was prepared through an indirect sulfonation procedure and then blended with PES at a certai...

SPES was prepared through an indirect sulfonation procedure and then blended with PES at a certain ratio. Applying SPES as the substrate affected membrane properties, such as porosity, total thickness, morphology, and hydrophilicity. The PES-based FO membrane with a finger-like structure had lower performance in comparison with the SPES based FO membrane having a sponge-like structure. The finger-like morphology changed to a sponge-like morphology with the increase in the SPES concentration. The FO membrane based on a more hydrophilic substrate via sulfonation had a sponge morphology and showed better water flux results. Water flux of 26.1 L m<sup>−2</sup> h<sup>−1</sup> and specific reverse solute flux of 0.66 g L<sup>−1</sup> were attained at a SPES blend ratio of 50 wt % when 3 M NaCl was used as the draw solution and DI water as feed solution under the FO mode. This work offers significant insights into understanding the factors affecting FO membrane performance, such as porosity and functionality.Soleyman SahebiMohammad KahriziNasim FadaieSoheil HadadpourBahman RamavandiRalph Rolly GonzalesMDPI AGarticleforward osmosishydrophilic substratesulfonated polyethersulfonethin-film compositenonwoven-embedded substrateChemical technologyTP1-1185Chemical engineeringTP155-156ENMembranes, Vol 11, Iss 813, p 813 (2021)
