Description
Summary:In the present work, a novel investigation on the effect of different type of polymers used as membrane substrates for application in pressure retarded osmosis was systematically conducted. Three asymmetric membranes with similar pore size but different polymers; polyethersulfone (PES), polysulfone (PSf), and polyphenylsulfone (PPSU) were used. The synthesized thin film composite (TFC) membranes were able to withstand with the applied pressure of 10 bar in pressure retarded osmosis mode when 1.0 M sodium chloride was used as draw solution and deionized water as a feed solution. Results showed that the PSf-TFC membrane gives a power density of 2.15 Wm-2, which is higher than that of the PPSU-TFC and PES-TFC membranes. It was found that the PSf-TFC is the most suitable substrate in this study with ideal porosity, good water and salt permeability, and low structural parameter which enhanced the power density.
