| Abstract: | This study focused on the surface modification of polyethersulfone (PES) microfiltration membranes using chitosan (CHS) and sodium alginate (ALG), specifically for the removal of textile dyes. The primary objective was to enhance membrane performance in terms of permeability and resistance to fouling, which is crucial for long-term use. A layer-by-layer (LbL) deposition technique was employed to coat the membrane surface with alternating layers of CHS and ALG, creating a bilayer configuration. Various characterization techniques, such as contact angle measurements, Fourier-transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM), confirmed successful membrane modification. These analyses demonstrated a slight reduction in hydrophilicity and decreased fouling. The performance of the modified membranes was evaluated using aqueous solutions of the reactive red 141 dye (RR141). Results showed that the modified membranes, especially MF CHS1ALG1 and MF CHS1ALG1.5, achieved remarkable dye removal efficiencies exceeding 98%. The MF CHS1ALG1.5 membrane was the top performer, attaining 100% dye rejection and approximately 70% flux recovery across four filtration cycles while maintaining dye rejection rates above 84%. Furthermore, tests using synthetic textile effluent with RR141 demonstrated high dye rejection (98.3%), highlighting the potential of this modification for treating textile effluent, even in the presence of salts.
