Abstract
The oil production was containing a very large amountof produced water, it was about 90% of fluids which brought up to the surface. Produced water contains several impurities which could affect the quality of surface water in the environment. This research was conducted in the conventional oil exploitation method at Wonocolo, Bojonegoro, Indonesia. At this oilfield, before the produced water discharge to the surface water, local people treat the produced water using gravity settling tank. Combine system was used for produced water treatment methodology in this research. The objective of this research was to obtain the efficiency of oilfield produced water treatment technology by conventional technology and membrane bioreactor. Nevertheless, from this research, we could determine how effective the treatment using chemical, physical, biological and ultrafiltration. In each unit operation of the treatment, removal efficiency was calculated. The methodology used in this study to attain the objectives were laboratory experiment using gravity separation, coagulation and flocculation, settling tank, aeration, and reverse osmosis. The total efficiency for the treatment with filter activated sand before ultrafiltration was 90,88% for Chemical Oxygen Demand (COD), 90,84 for Total Dissolved Solid (TDS), 93,33% for Total Suspended Solid (TSS), and 99,7% for turbidity. High removal efficiency result using this technology, it is possible to recycle the produced water as raw water for daily use. Key-words: oilfield produced water, produced water treatment, combine system, coagulation process, membrane bioreactor.
