Abstract

Abstract: Membrane separation technology has been widely applied in various industrial sectors. Some modification on membrane composition and structure is conducted to improve membrane filtration performance and mitigate fouling phenomena. Fouling on membrane surfaces lead to decrease permeabilty, increase energy consumtion, and shorten membrane life time. The aim of this study is to manufacture PES membrane which involved inorganic additives consits of Carbon and Fe2 O3 particles to mitigate fouling tendency. All of membranes were prepared using phase inversion method with dissolving PES polymer into dimethyl formamide (DMF). The result membranes were characterized using Scanning Electron Microscopy (SEM) to investigate morphological structure and breaking strength to determine mechanical property. Membrane filtration performance were tested using soy protein solution in cross-flow system. The results showed that the addition of inorganic particles in PES membrane caused the increasing of pores which lead to increase pure water flux from 15.14 L/m 2 .h to 58.67 L/m 2 .h. Fouling mitigation test towards soy protein also showed that carbon and Fe2 O3 particles enhanced membrane flux recovery ratio from 64.5 to 76%. Furthermore, the inorganic particles presence in PES membrane also improved the tensile strength of membrane up to 128 Mpa.
