When treating the exhausted baths etching industries metalized plastic is used an electrochemical reactor of the filter press type pilot scale as the recovery of hexavalent chromium by oxidation of trivalent chromium on an anode lead. This research focused on the study of a reactor of that type, in order to study their behavior operating in potentiostatic mode of 5 and 7.5 V, with real solutions etching baths. Basic parameters were evaluated for designing electrochemical reactors such as: electrical performance, the conversion reached, the specific productivity and specific energy consumed coupling the electrochemical reactor one and two ceramic separators manufactured 250 kg/cm2 and 0 % starch.
