Resumen
The textile industry is the second most polluting globally, the amounts of water used in the dyeing processes of natural or synthetic fibers exceed 200 liters per kilogram of processed product, which is why there is a need to investigate appropriate technologies that allow treatment and reuse of this wastewater. To determine the efficiency of electrocoagulation in textile wastewater using aluminum as the sacrificial electrode, a 3x3x3 Latin square methodological design was carried out, with current intensity (I), time (t) and temperature as experimental variables. contact area or surface and as response variables conductivity, turbidity, pH and COD. It was found that the relationship between the experimental variables with pH is directly proportional, while with the other response variables it is inversely proportional. Additionally, the highest efficiency in contaminant removal was achieved with a retention time of 30 minutes, 5 Amps and 600 cm2, achieving 97.94% removal in Turbidity and 88.67% in COD. The treatment of wastewater from the textile industry through electrocoagulation cells allows, in addition to complying with current legislation on discharges to surface water bodies at the national level (Resolution 631 of 2015), to comply with resolution 1207 of 2014, generating water with physicochemical characteristics that can be reused in agricultural or industrial uses.
