Membranes from blending of chitosan with hydrophobic polymers Polyethersulfone (PES) and Polyvinylidene Fluoride (PVDF) have been prepared, characterized, and evaluated in terms of antifouling properties against humus acid contained in water. The preparation of membrane adapts the common phase inversion technique, whereas the filtration performance test was done by using crossflow set-up. The findings of the work showed that the addition of 5% chitosan into the casting solution increased the permeability of both hydrophobic membranes. The positive outcome from the increased hydrophilicity simultaneously results in a higher pure water flux of the chitosan-blended membranes compared to the original ones. Not only that, the modification also improves the antifouling properties of the membranes which shown from an increase in Flux Recovery Ratio (FRR) of 92% and 88% respectively for PES and PVDF membranes with the addition of 5% chitosan. The obtained results evidenced that golden snail shell is a potential modifier for membrane production. © 2024 Author(s).
