The aim of this study is to investigate the effect of surface modified of PVDF membranes by adding the hydrophilic additives for refinery produced wastewater treatment. This paper presents the results of a research on direct clean water treatment using hollow fiber ultrafiltration. The source of water is the synthetic refinery wastewater with mixed liquor suspended solids (MLSS) concentration of 3 g/l. All experiments were conducted at 25oC and 0.5 bar absolute. The morphological and performance tests were conducted on PVDF ultrafiltration membranes prepared from different additives concentrations. The cross sectional area of the hollow fiber membranes was observed using a field emission scanning electron microscope (FESEM). The surface wettability of porous membranes was determined by measurement of contact angle. Mean pore size and surface porosity were calculated based on the permeate flux. The results also indicated that the PVDF composite membranes with lower additives concentration loading possessed smaller mean pore size, more apertures inside the membranes with enhanced membrane hydrophilicity. The flux and rejection of refinery wastewater using PVDF composite membrane achieved 140.82 L/m2h and 98.8 % , respectively.
