In order to evaluate the treatability of the effluents generated from a metallurgical laboratory by means of electrocoagulation, an electrocoagulator was designed to scale with dimensions of 40.8 cm long, 10.6 cm wide and 14 cm high with a capacity of 6,168 L 20 plates were used for each test of iron and aluminum and these plates were connected in parallel with a bipolar configuration to a direct current source. The best conditions for the removal of metals (lead, cadmium and chromium) were: material of the aluminum electrodes, a distance between plates of 1 cm and a retention time of 60 minutes. Taking these conditions as the most efficient scenario, the electrocoagulation process reduced lead by 94.47 percent, cadmium by 46.11 percent and chromium by 49.46 percent. For lead and cadmium, despite the removal obtained, they were not within the Maximum Admissible Values, unlike the chromium that prior to the treatment was already within the allowed. In addition, during the process hydrogen sulfide gas was generated in low concentrations, which was perceived as a rotten egg odor during the process.
