  • This research used ultrafiltration membrane modules in the separation process of Total Suspended Solid (TSS) from lubricating oil waste. Ultrafiltration was a process to separate or concentrate a solution containing colloidal, materials with high molecular weight, with membrane. After the initial treatment of lubricating oil purification with ultrafiltration process, it appears that there was a decrease of TSS levels in permeate up to 295 mg/liter, compared to the levels of initial TSS material which is 1880 mg/liter. The analysis result of flashpoint parameter, water content and the sulfur content shows a value that has met standard specifications of fuel oil while the viscosity values was not meet the standard. Increasing the operating pressure will decrease the flux, as well as with increasing time will also reduce the value of flux until a certain time point. While the increase of % rejection occurs with the increasing pressure and operation time. The best condition that can be achieved in the purification of used oil with ultrafiltration process is by using a Cellulose Acetate membrane (pore diameter 0,48 m) which was operating at a pressure of 0,68 bar with the operating time of 120 minutes with TSS content of 295 mg/l and 84,3085 % rejection. Results of the study indicated that the ultrafiltration membrane can be used in the purification of used oil and the outgoing permeate can be used as fuel oil.
