Can MoS2 increase fouling when incorporated in UF membranes?
4 answers
Incorporating MoS2 into ultrafiltration (UF) membranes can actually reduce fouling rather than increase it. Various studies have shown that MoS2-based membranes exhibit improved hydrophilicity, anti-fouling properties, and enhanced permeability. MoS2 modifications lead to increased hydrophilicity, surface roughness, and negative charge, which collectively contribute to mitigating fouling and enhancing membrane performance. Additionally, MoS2 nanoparticles have been found to promote the formation of porous structures, improve hydrophilicity, and enhance anti-fouling capabilities of membranes. The incorporation of MoS2 nanosheets has been shown to increase pure water flux, maintain stable rejection rates, and enhance organic removal, all while demonstrating excellent fouling resistance. Therefore, MoS2 incorporation in UF membranes can actually improve their performance and reduce fouling tendencies.
