Abstract: This invention relates to a produced water treatment system composed of 10 stages which are: I) Fine Screening II) Homogenization, equalization and flow regulation III) PH adjustment IV) Electrofloculation and/or electrocoagulation and/or broad impact ionization V) Primary repumping VI) Clarification VII) Sludge Treatment VIII) Advanced Oxidation IX) Filtration System X) Reverse Osmosis Achieving with this quality process in the final water discharge the official standard norm and any other required norm. The objective of this invention is to contribute to the improvement of the ecosystem, with a more economical process without the need of an ultrafiltration system, obtaining better results in the treatment of produced water.
