The Substrate membrane was prepared by phase inversion technique using polyethersulfone (PES) and dimethylacetamide (DMAc) as solvent with and without the addition of polyvinylpyrrolidone (PVP) as pore-forming agent. The effects of the composition of the casting solution on membrane morphology and water permeation were investigated. The membrane prepared from 15 wt % PES with 2.25 wt % PVP demonstrated better water permeability compared to other compositions. CS/PES composite membrane flux and retention were 5.2 lit/m2hr and 76.15%, respectively. The mean pore size of the composite membrane was calculated as 0.99 nm.
