Abstract
In this study, cellulose acetate (CA) membrane was prepared by phase inversion precipitation and then evaluated the forward osmosis (FO) membrane performance. Differences in water flux and salt rejection between RO and FO with prepared membranes were observed. The different structure membranes were prepared with various solvent which evaluate the influence of membrane structure on permeability. The structure of the prepared membrane was confirmed through scanning electron microscopy (SEM) and the permeability changes were estimated using the bench-scale FO test equipment.
