This research demonstrates how sulfonated polysulfone improves hydrophilicity and anti-fouling properties in CPVC membranes, suggesting better efficiency for wastewater treatment.
Chlorinated Polyvinyl Chloride (CPVC) is considered a suitable membrane material for wastewater treatment due to its low cost and good chemical properties. However, the inherent hydrophobicity of CPVC membranes compromises their anti‐fouling performance, thereby negatively impacting wastewater treatment efficiency. To enhance the hydrophilicity and anti‐fouling properties of CPVC ultrafiltration membranes, this study incorporated sulfonated Polysulfone (SPSF) into CPVC through blending. CPVC/SPSF blend ultrafiltration membranes were fabricated via the non‐solvent induced phase separation (NIPS) process, and the effects of SPSF concentration on membrane structure and performance were systematically investigated. The results demonstrated that the incorporation of SPSF significantly enhanced membrane hydrophilicity, permeation flux, and anti‐fouling properties, while reducing mechanical strength. Additionally, the addition of SPSF improved the thermal stability of the membranes. This research provides new insights into the development of high‐performance CPVC ultrafiltration membranes.
