Diseño de un electrocoagulador para el tratamiento de aguas residuales de la industria láctea FAMILAC del cantón Chambo.

Abstract

The objective of the present titration work was to design an electrocoagulator for the wastewater treatment of the FAMILAC dairy industry in the canton of Chambo, because the wastewater generated by the industry is discharged directly into the sewer without any previous treatment. It was indicated with a sampling of the residual water for subsequent physical-chemical characterization. From this, the parameters that are out of regulation were determined: Oils and fats, BOD5, COD, TSS, TS, and S. Then the effluent was treated by electrocoagulation; For this, a test cell was designed, whose variables were electrode distribution, current intensity and treatment time. Mathematical calculations were developed for the sizing of the electro coagulator and as a complement to the treatment system, a sedimentation system was designed. The design was validated with the most effective treatment that presents a distribution of electrodes A1-A1, the current intensity of 3 amps and a time of 15 minutes, under these conditions the 95.5% oil and grease is removed, 84.5% BOD5,83.0 % COD, 98.7% TSS, 61.4% TS and 92.2%. In conclusion, with the proposed design, it is possible to reduce the degree of contamination of wastewater and comply fully with the norm quoted in TULSMA, Table 8: Discharge limits to the public sewer system. It is recommended that the dairy industry FAMILAC implement this technique for the treatment of wastewater due to the high percentage of removal of contaminants.
