SUMMARY:

When oil is extracted from different production zones from onshore or offshore deposits, it produces aqueous waste called oilfield wastewater or produced water (PW), which represents the largest amount of waste from crude oil production. The produced water contains several organic and inorganic components, which its main constituents involve formation salts, dissolved gases, suspended solids, organic compounds from contact with oil, residual chemical compounds from operations in the well, microorganisms, in addition to the possible presence of heavy metals and components with some type of radiation and their discharge may pollute surface, groundwater and soil. For this water to be released in the environment or reused in the industry itself, it must be treated in a way that it does not constitute a real danger to the ecosystems where it will be discharged, as well as in the wells where it is produced (reinjection) , since through its chemical composition, it can somehow favor corrosive damage to pipes, etc.
One of the most used processes for the treatment of this type of effluents has been the advanced oxidative electrochemical processes. For this purpose, the aim of this work was to evaluate the effect of the IrO2 anode on the removal of the organic charge from a sample of Real Produced Water at 30, 60, 90 mA / cm2 of current density, and it was also to determine and to evaluate the effect of “active chlorine” species in the disinfection of the same sample rich in chloride and sulfate ions, proving to be ideal for the electrochemical obtaining of water disinfectants. Thus, as a result, the anode allowed the removal of about 79%; 73.5%; 76.9% of COD with EC of 48,768; 129.54; 244,602 kWh/dm3 at 30, 60, 90 mA / cm2 of current density, respectively, has also shown electrocatalytic properties to obtain active chlorine species with better efficiency at 30 mA /cm2 of current density.
