Industrial effluents containing dyes are difficult to biodegrade due to their complex molecular structure and synthetic origin. This study removes Congo red dye (CRD) using polysulfone (PSF)-based flat sheet membrane by phase in version technique. PSF 18% is coated with different amounts of chitosan solution (0.1, 0.25, 0.5, and 1%) and loaded with Jamun leaf ash as bio-sorbent (0.1, 0.2, 0.4, 0.6, and 0.8 g). Chitosan and Jamun leaf ash both are easily available, eco-friendly, and low-cost materials. Chitosan acts as hydrophilic additive material towards improving the antifouling properties and performance of PSF membranes. The removal efficiency of CRD is measured using a dead-end filtration setup. PSF 18% coated with 0.25% chitosan showed 98% removal efficiency with 89 l/hm2 flow rate. PSF 18% without chitosan coating showed 91% efficiency at 0.6 gm bio-sorbent loading. PSF 18% coated with 0.25% chitosan and bio-sorbent 0.2, 0.4, and 0.6 g showed 100% removal efficiency with 57.32 l/hm2 flow rate. Electrostatic attraction occurred between chitosan (cation) and CRD molecules (anion). Therefore, with increased chitosan coating (%wt), percentage rejection increased, and the flux decreased.
