EVALUATION OF THE EFFECTIVENESS IN THE RECOVERY OF WATER CONTAMINATED BY HYDROCARBONS, THROUGH THE TECHNIQUE OF PHYTOREMEDIATION USING VETIVER GRASS

The present work was based on the study and evaluation of an alternative treatment, for the reduction of the pollutant load of the production residual waters, generated in the oil field of Chichemene, in the department of Meta, located in the region of the eastern plains of Colombia. The methodology used was based on phases, where in the first phase a diagnosis of the hydrocarbon production process in an oil field was made, in the second phase the state of the art of the phytoremediation process of the production waters was investigated, using the vetiver grass technique, in the third and last phase, some treatment alternatives were selected that, together with the pilot cultivation of vetiver, reduce the contaminating load of the production waters in an oil field. The activities carried out in the development of this work allowed to synthesize the following results: identification of the chemical components that the production water has; the treatment system of the water produced by the vetiver grass technique, in order to reduce the pollutant loads in the production water in the Chichemene Field.
