| Abstract: | In the present study, waste drilling muds from an active drilling operation were used to evaluate the feasibility and efficiency of bioremediation in the laboratory during a one-year trial and following a phytoremediation treatment. The results showed that total organic carbon (TOC) content in the muds decreased from 89800 to 21700 mg/kg after 48 h of biotreatment in a slurry reactor, and the chroma removal efficiency reached 81.5%. TOC contamination level was decreased by 84.6% after 240 days of phytoremediation. |
