Area of Science:

  • Materials Science
  • Chemical Engineering
  • Environmental Science

Background:

  • Organic fouling remains a significant challenge in thin film composite (TFC) nanofiltration (NF) membranes, reducing their efficiency and lifespan.
  • Existing surface modification methods often involve harsh chemicals or complex procedures, limiting their practical application.

Purpose of the Study:

  • To develop a novel, eco-friendly surface coating technique for TFC NF membranes.
  • To mitigate organic fouling while preserving or enhancing membrane permselectivity.
  • To evaluate the scalability and cost-effectiveness of the proposed method.

Main Methods:

  • Mist-based interfacial polymerization was employed to create a spot-like polyester (PE) coating on polyamide (PA) TFC membranes.
  • Different concentrations of sulfonated kraft lignin (SKL) and trimesoyl chloride (TMC) were used in the coating process.
  • Membrane surface properties (zeta potential, roughness) and performance (flux recovery ratio, salt rejection) were analyzed before and after coating.

Main Results:

  • PE-coated membranes exhibited enhanced negative surface charge and reduced surface roughness compared to the control PA membrane.
  • The membrane coated with 7 wt % SKL achieved a 90% flux recovery ratio during Bovine Serum Albumin (BSA) filtration, a 15% improvement over the control.
  • Coated membranes demonstrated stable separation performance and robustness over 40 hours of filtration.

Conclusions:

  • The developed mist-based interfacial polymerization is an effective and sustainable method for surface modification of TFC NF membranes.
  • The PE coating significantly improves fouling resistance without compromising separation performance.
  • The technique is scalable, cost-effective, and offers a promising solution for advanced membrane applications.
