520	3		_aThis report shows the performance of flat sheet polyvinyl alcohol (PYA) blend chitosan (CS) membrane with different concentration polyethylene glycol (pEG) 200 as additives. The main objective of this research is to fabricate high solute separation and flux membrane. The membrane were prepared by dry phase inversion method from casting solution containing PV A and CS as polymer, formic acid (FA) as solvent and PEG 200 with concentration of 3 % and 5 % as additives. The membranes were characterized in terms of pure water permeation (PWP), solute separation (R), flux (J) and membrane morphology are observed using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The results revealed that pure water permeation increases almost linearly when concentration of PEG 200 is increased from 3 % to 5 wt%. The solute separation and flux for both Bovine Serum Albumin (BSA) and lysozyme are also increased linearly when concentration of PEG 200 is increased from 3 % to 5 %. From the observation using SEM, as concentration of PEG 200 is increased in the casting solution, the number of pore sizes is increased. This contributes to high flux and pure water permeation. Then, when using AFM, it shows that the roughness parameter of membranes increased with increasing of PEG 200 as additive. This is due to the nodules is not merged and the number of pores increased. -Author
