Preparation of Cellulose Acetate Membrane and Its Evaluation as a Forward Osmosis Membrane
(Received March 30, 2014, Revised April 25, 2014, Accepted April 29, 2014)
Abstract
In this study, cellulose acetate (CA) membrane was prepared by phase inversion precipitation and then evaluatedthe forward osmosis (FO) membrane performance. Differences in water flux and salt rejection between RO and FOwith prepared membranes were observed. The different structure membranes were prepared with various solvent which evaluatethe influence of membrane structure on permeability. The structure of the prepared membrane was confirmed throughscanning electron microscopy (SEM) and the permeability changes were estimated using the bench-scale FO test equipment.
