Abstract

In this study, acetylated methyl cellulose (AMC) was successfully used as a support layer of thin film composite(TFC) forward osmosis (FO) membrane. A selective polyamide active layer, interfacially polymerized, was coated ontop of various substrate layers. The structure and performance of the TFC FO membrane based on the AMC substrate werecompared with those of TFC FO membranes with different polymeric support layers. The experimental results showed thatthe AMC FO membrane performance was better than other FO membranes due to its characteristic morphology and lowerback diffusion rate of salts.

Key Words : acetylated methyl cellulose,thin film composite,forward osmosis
