Description of behavior of a prototype for the electrochemical treatment of industrial waste waters

Abstract

It is described in this study the behavior of a prototype of electrocoagulation as an option for industrial wastewater treatment, evaluating the efficiency of reduction of heavy metals such as zinc, nickel, chromium (total and hexavalent) and lead. The prototype is powered by waste water from galvanic and tannery industries of the city of Bogotá. The prototype was used as anode and cathode plates of iron and copper respectively, supported by copper rods to drive electricity and separated by a wooden structure (non-conductive material). The reaction is carried out in a dielectric in acrylic. The system design is based on a circuit resistive direct current (dc), where the load is represented by the effluent, resulting that the efficiency of reduction of heavy metals was 73%. According to these results, the conclusion is that the system studied can be useful in the production of clean industries.
