Treatment of Crude Oil Spills in Water Resources by Using Biological Method

Abstract

Abstract- Biological treatment has definite to be an effective and excellent methodfor the removal of aquatic oil spills. It is competent of being used as the besttreatment method for cleanup of oil spills. Being a potential technology, significantwork needs to be done to improve the capabilities of bioremediation for oilcontaminated-aquatic environment. Novel application of combined solventextraction and two-phase biodegradation processes using Two-Liquid PhasePartitioning Bioreactor (TLPPB) technique was proposed and developed toenhance the cleanup of high concentration of crude oil from aqueous phase usingacclimated mixed consortiums in an anaerobic environment. Silicone oil was usedas the organic extractive phase for being a water-immiscible, biocompatible andnon-biodegradable. An application of one phase bioreactor was used, then“TLPPB” two-liquid phase partitioning bioreactor was sophisticated to decayhydrocarbons “crude oil” in this study) at concentration reach to 6000 mg/L. As theorganic phase, Silicon oil was selected in TLPPB technique to hold the delivery ofhydrocarbons in a liquid layer by absorbing method and after that transforming thepollution to the biological microorganisms. Based on TLPPB technique, theeffectiveness of the organic layer “silicon oil” has been contrasted to the one-phasebiological reactor. Then the result is completely treated of hydrocarbons pollutantto 100% was accomplished in the two-liquid phase partitioning bioreactor“TLPPB” contrasted to 69-78% treated efficiency of crude oil in the one-phasetraditional biological reactor. Thus, the interpretation of “TLPPB” technique forcrude oil treatment was estimated in terms of the salinity influence by using Tigrisriver water, and sea water samples. The rising rate of salinity in liquid layercausing reduction the microorganisms-activity and prohibit the amount of crude oildecay. Thus, this research mentions the possibility of TLPPB technique forconsolidate transmission and the biodegradation of immiscible crude oil.
