Summary:Wastewater from the oil industry treatment is very difficult to achieve in an uniform matter. Therefore, pre-treatment steps are often required in order to reduce the compounds' elimination and to determine which treatment cannot be eliminated in the biological stage. Application of a pre-treatment process eliminates certain compounds with specific microorganisms that do not fit with the activated sludge. In this paper, the details of this solution were studied. It was established a reduction of the benzene concentration from 82.23 mg/L to 18.04 mg/L, toluene 3.08 mg/L to 1.15 mg/L, xylene at 4.1 mg/L to 3.1 mg/L and naphthalene 7.08 mg/L to 4.96 mg/L. Experiments have shown a decrease of the polycyclic aromatic hydrocarbons concentration below the limit of detection of the device.
