| Abstract | Oily sludge resulting from refineries is threatening the environment and human health. Traditionalclean-up methods of oily sludge have limitations in efficiency, environmental effects and cost. Acombination of froth flotation and biosurfactants method was established for treating oily sludgethat generated from the south refineries company, Basrah Governorate, Iraq. This work presents apart of an ongoing project to develop an appropriate low-cost and sustainable method to recoveroil from refinery oily sludge. Biosurfactants driven from Bacillus cereus were produced, extractedand evaluated for their effectiveness as frothing agent. Flotation parameters including biosurfactantsconcentrations, air-water ratio, temperature and flotation time were determined for efficient separationof oil from oil-in-water emulsion. The optimum conditions revealed by this study were 0.2 g/Lbiosurfactant concentration, 15% air-water ratio, 30 °C and 25 minutes flotation time. The obtainedresults showed that the combined method demonstrated a significant oil removal (90%) in comparewith flotation alone (60%). The GC-MS analysis showed near complete removal of hydrocarbonsconfirming the effectiveness of this method in oil separation and enhancing oil removal. This findingsuggests that the combined approach is a promising and sustainable strategy for oily sludge treatment.Further studies are required to validate the efficiency of this method in large-scale applications. |
