PINEDO-HERNANDEZ, Jose; PATERNINA-URIBE, Roberth  e  MARRUGO-NEGRETE, Jose. Alternative Electrocoagulation for Livestock Wastewater Treatment. Port. Electrochim. Acta [online]. 2016, vol.34, n.4, pp.277-285. ISSN 0872-1904.  https://doi.org/10.4152/pea.201604277.

This project assessed the technical feasibility of organic matter (COD) removal in livestock effluents, by electrocoagulation. An experimental design was used to block two factors at three levels, to evaluate the effect of the variables distance between electrodes and pH, using aluminum sacrificial electrodes. Maximum removal (90.16%) was obtained at 7 units pH, and 2.0 cm distance between electrodes. This study demonstrated the technical feasibility of electrocoagulation (EC) for the removal of organic matter as COD, present in wastewater from the livestock industry.
