Many industries engaged in metal coating generate industrial effluents with a high degree of heavy metals, with potential damage to the environment and health. The company dedicated to this industrial area sends its industrial effluents to an industrial sanitary landfill through a third company. However, it is looking for an alternative to treat the industrial effect, minimizing the presence of heavy metals such as zinc, nickel and chromium and then be discharged to the sewer system, complying with current regulations. In this study it was proposed to treat the industrial effluent by the electrocoagulation technique. To have previous results to the treatment of the effluent, experimental tests were carried out with a synthetic sample under a batch system and another continuous system whose content for both is formed by the Chromium (+6) , Nickel (+2) and Zinc (+2) in order to establish operating parameters such as pH, temperature, time and current density; show results as percent removal of the metals under study, conductivity and total solids. The optical values of operation that were obtained with the synthetic sign under a system by the lots were with a current intensity, with a pH of 7,90 and a treatment time of 20 minutes, whose percentages of removal were 100% for all metals. In treating the synthetic sample with the continuous system, the values were obtained with a current intensity 166.7 A/m2, with a flow of 50 ml/min, with a pH of 7.80 and a treatment time of 30 minutes, whose percentages of removal were 97.8% of Cr +6, 99,7% of Ni 2+ and 99.5% de Zn2+. For systems compliant with current regulations of the country. By applying these optimum operating parameters to the effect, the following results were obtained; 99.2% of Cr +6, 97,7% of Ni 2+ and 95.0% de Zn2+ were removed in the batch system and 97.9% of Cr +6, 96.4% of Ni 2+ and 93.6% de Zn2+ were removed in the continuous system. Thus, in all systems has been complied with the current regulations for the dumping of the sewerage system
