Use of Polysulfone-g-Polystyrene / Cellulose / Poly (ethylene teraftalate) Composite Membranes in Osmotic Distillation

Abstract

In this study, fructose solutions were used to concentrate polysulfone-g-polystyrene (PSf-g-PS) graft copolymers with composite membranes prepared with cellulose / poly (ethylene terephthalate) (CV/PET) using osmotic distillation method. The membranes were prepared by the phase inversion method and characterized by Scanning Electron Microscopy (SEM). The effects of various process parameters such as feed and brine solutions concentrations, type of brine and temperature on flux were investigated. The increase in temperature increased the flux. The highest flux in brine solution concentration was observed in the concentration close to saturation. The highest flow was obtained in MgCl2.
