Removal of the impurities provides a possibility of reusing waste engine oils as well as decreasing waste disposal to the environment. In this study, the hydrophobic polypropylene membrane (PP) was used for ultrafiltration (UF) of waste engine oils. Membrane performance (in terms of oil flux and impurities rejection) as a function of operating pressure (0.4-1.2 bar) and temperature (30-60 oC) was investigated. Results show that the oil flux increases with applied pressure and temperature while rejections of impurities are relatively stable. Within the range of operating conditions, the oil flux is from 0.09 to 0.19 L.m-2. h-1. The membrane can remove ash content (90-99 %), water (78-82.5 %), carbon residue (52.6-65.9 %), acidity (44.9-73.3 %), calcium (50.1-58.9 %), and zinc (28.9-43.8 %) effectively. Removal of those impurities results in the improvement of treated oil quality evidenced by the change of kinematic viscosity, density, and color. It was also observed that the filtration of waste engine oil results in increasing PP membrane wettability towards oil-(water contact angle increased from 101.4° to 102.9° and oil contact angle decreased from 48.2° to 45.3°).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Hazardous compounds,Membrane performance,Membrane wettability,Operating condition,Operating pressure,Polypropylene membrane,Ultra-filtration membranes,Water contact angle[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Flux,Hydrophobic,Oil disposal,Waste engine oil,Wettability[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research is partially funded by Ministry of Energy and Mineral Resources, Indonesia (scholarship for S.
