. In recent years, the Government of Baja California has promoted not to discharge wastewater with high content of fats and oils. A company in the region dedicated to the collection of sludge, installed a horizontal centrifugation system for the extraction of oil, generating a sludge with 5% fat and oil. The result of this process is sent to a process of biodigestion and vermicompost for the generation of solid and liquid humus, which generates wastewater with high organic load that require a treatment before disposal. Objective. Develop an experimental prototype of electroflocculation to wastewater treatment with a high content of organic matter. Methodology was divided into 4 stages: 1) Physicochemical and biological characterization of the wastewater; 2) Assembly of the electroflocculation prototype; 3) Experimental assessment 4) Verification of system operation. Contribution. Through the elaboration of the prototype, the effectiveness of the electroflocculation process was confirmed for the wastewater treatment (WT) with a high content of organic matter (OM) and pathogenic bacteria, since a greater than 50% decrease of the biochemical oxygen demand (BOD5), chemical demand of oxygen (COD), fecal coliforms and Salmonella.
