Novel Thin-Film Nanocomposite Forward Osmosis Membranes Modified with WS2/CuAl LDH Nanocomposite to Enhance Desalination and Anti-fouling Performance

Designing efficient membranes for desalination to help reduce the water shortage crisis has been subject of various studies. In this study, first, CuAl LDH nanosheets were prepared and surface some thin-film composite (TFC) was modified by them. Afterward, novel heterostructure nanocomposite consisting WS2 synthesized hydrothermal method, a new kind (TFN) made using All obtained performance studied in forward osmosis (FO) process. The effects compounds on morphology, chemical structure, hydrophilicity, topology polyamide (PA) active layer evaluated scanning electron microscopy (SEM), FT-IR spectroscopy, energy-dispersive X-ray (EDX), powder x-ray diffraction (XRD), contact angle (WCA) goniometer atomic force microscope (AFM) analysis. Finally, comparing results both types membranes, membrane containing 0.025 wt% modifier showed highest flux (29.30 LMH) selectivity (0.38 g/L) that chosen as optimal membrane. Also, anti-fouling properties an increase fouling resistance compared without filler.
