Abstract

Abstract: Selection of the appropriate solvent plays an important role in the characteristics of the membrane formation. Flat-sheet polyethersulfone (PES) membranes were formation via non-solvents induced phase separation (NIPS) technique. PES as a polymer, Brij58 as hydrophilic surfactant and three types of solvent were used to prepare the dope solution. This paper attempts to show the effects of three different solvents there are; dimethylsulfoxide (DMSO), dimethylformamide (DMF), and dimethylacetamide (DMAc) on characterizations and performance of fabricated membranes. The fabricated membranes in this study were characterized by measuring water contact angle and mechanical properties. The performance of fabricated membranes was carried out using a dead-end ultrafiltration module. Solubility between solvent and non-solvent is an essential factor in the membrane formation process. The porosity of membrane fabricated from the system of PES/Brij/DMAc was higher than membrane made from another system, so that the water permeability of this membrane was higher than others. The membrane fabricated with DMAc as solvent had a tensile strength of 12.42 kgf/mm 2 .
