Popis:	This work presents the preparation and modification of hybrid Mg(OH)2/chitosan blended PES membranes with the aim of improving the hydrophilic, antifouling and performance of the resulting membranes. The deposition of additives by blending the polymer with a concentration of 1%, 3%, 5%, and 7% on PES membranes. The influences from varying concentrations of additives were evaluated by analyzing changes in chemical groups, changes in morphological structure, hydrophilicity degree, porosity, filtration properties, and the antifouling propensity of the fabricated membrane. PES membranes with the addition of 5% additive (MC-5) showed the best performance biggest degree of hydrophilicity compared to the other membranes. In terms of performance, the MC-5 membrane produces a PWP of almost 15 folds bigger than that of unmodified PES, with a rejection value of 68.2% and a water flux recovery ratio (FRw) of 82.7%.
