PEREZ-SICAIROS, S.; MORALES-CUEVAS, J.B.; FELIX-NAVARRO, R.M.  e  HERNANDEZ-CALDERON, O.M.. Evaluation of the electro-coagulation process for the removal of turbidity of river water, wastewater and pond water. Rev. Mex. Ing. Quím [online]. 2011, vol.10, n.1, pp.79-91. ISSN 1665-2738.

In this work, the removal of water turbidity was studied from three sources: Tamazula River, the Degremont Wastewater Treatment Plant and a pond of a botanical garden in the region of Culiacan, Sinaloa. For this purpose, parallel plate and continuous flow electrochemical reactors were constructed, both with perforated plate aluminum anodes and iron mesh cathodes, for the application of electro-coagulation. The process variables studied were the applied current and the concentration of supporting electrolyte, in the case of parallel plate reactor and also the volumetric flow rate, in the case of continuous flow reactor. According to the results, it is possible to eliminate the turbidity of the Tamazula river water with this process, achieving compliance with the official Mexican standards under the conditions studied. The general conclusion is that the electro-coagulation process has a great potential for application in turbidity removal for treatment of the three types of water sources used.
