RESUMO:

During the exploitation of oil and gas onshore and offshore, it is also simultaneously the production of water commonly produced water call or production water. Produced water (AP) is the pollutant that most prominent because of its large volume and its toxic chemical composition, among the various contaminants are present in the AP: soluble and insoluble organic compounds. There are several types of chemical treatment, physical, physico-chemical and biological processes that can be combined for the purpose of higher efficiency in reducing of pollutants ensuring that the final effluent is in accordance with current environmental laws (CONAMA). The work has as main objective to evaluate technically, the integration of filtration processes, adsorption and photo-Fenton of the removal of oils and greases Total (TOG) and total organic carbon (TOC) present in the effluent. The processes were first studied individually in the final together. The combined process consisted of using a sand filter with mixed grain size (12/16 mesh, 36 mesh, 20/28 mesh and 12/16 mesh), activated carbon column (activated carbon from babaçu coconut shell) and the last step was the photo - Fenton process using a photochemical reactor 400 w mercury vapor lamp. In this step the synthetic effluent was prepared from a mixture of components (NaCl, phenol, heptane, xylene, distilled water and oil 1 (grade API ° 15) and oil 2 (API ° 22) using a agitator (Turratec / Tecnal) for better homogenization was shaked for 20 minutes at 18000 rpm. The initial effluent was passed into the filter and adsorption column continuously until obtaining 6L treated effluent, then the effluent was taken to the reactor photochemical to degrade the remaining contaminants of the prior processes. Considering the reduction of the TOG the combined process efficiency was 98.8%, only the filtration reduced 90%. With regard to TOC reduction the overall efficiency of the combined process it was 99%, with the steps of adsorption and photo-Fenton the greater efficiency the combination of filtration processes, absorption and photo - Fenton was effective both in reducing the TOG as the TOC reduction of the produced water
