Abstract

Membrane is an important part in ultrafiltration process to split up water from its impurities. Commonly membranes are made of polymer which has adequate resistance in filtration process. One type of them is polysulfone. Good physical endurance is its supremacy as material in the manufacture of membranes. Nevertheless, the hydrophobic nature of polysulfone makes membrane performance less efficient. Blending process using TiO2 can lessen the hydrophobicity of polysulfone, but still maintain membrane primacy. The blending process was carried out by the phase inversion method. Membrane physical structure was observed by SEM and XRD analysis. The pore arrangement on both membranes looks asymmetric. However, the PSF/TiO2 membrane has more systematic pore disposition. Good crystallinity was noticed on PSF/TiO2 membranes with crystal size of 27 nm whereas pure polysulfone looks more amorphous. Membrane performance can be discerned by considering various parameters after performance tests by using diesel fuel emulsion in water.  Some of these parameters include flux, rejection, and total fouling after the emulsion filtration process. PSF/ TiO2 membrane flux values ​​showed better results at 21.05 L/m2 hour. Rejection of the PSF/TiO2membrane  looked better as well, spesifically 70,857%. Total fouling showed preferable result on the PSF/TiO2 membrane, which was 42.34%. The insertion of TiO2by a composition of 10% of the total PSF used can improve membrane performance and morphology.
