Diseño de un electrocoagulador para aguas industriales clarificadas de la Empresa Plusambiente base cantón Joya de los Sachas, provincia de Orellana.

Abstract

The current work has like objective to design an electro-coagulator for clarified industrial water of Plusambiente Company, host plant, La Joya de los Sachas canton Orellana province, in order to increase the efficacy in treatment and to reduce the pollution degree in water. It was started with the sample and later characterization of water based on the Environmental regulations for Hydrocarbons Operations of Ecuador, determining the parameters that influence in the pollution, being the electrical conductivity, total solids and chemical demand of oxygen. The science and technology usage helped to make testing the treatability, through a simulation of process to lab scale, in which variables and conditions proper for the functioning were determining being the most important: the type anode, cathode, spatial distribution, electrolysis time, current intensity, and the equipment functioning model. The engineering calculations for design of electro-coagulator and a settling was dimensioned like complement for the process. The proposed design was validated with the results of final water characterization, obtaining removals of 53% of electrical conductivity, 25,41% of total solids, and 35,78% of chemical oxygen demand. In conclusion, with the proposed design, the degree of clarified water pollution decreased, but the regulation does not carried out. It is recommended to the plant engineers of Company that the model of design be effective in order to treat the water, and it is suggested that carried out investigations about the use of inert electrodes, filter systems and electrodialysis that could be possible applications before of treatment by electrocoagulation.
