Aplicación de una celda electrolítica en el tratamiento de aguas provenientes de la producción del queso.

Abstract

This research was carried out in order to know the efficiency of an alternative system for the treatment of wastewater from the dairy industry; for the development of this study synthetic wastewater was used that was subjected to an electrochemical process, in order to observe and analyze the effect of this in certain physical properties of water such as the reduction of chemical oxygen demand (COD), the conductivity, the pH, the hardness and the concentration of ammoniacal N2. This study determined the most convenient variables for the electrochemical treatment, evaluating the material and the combination of the electrodes, the voltage potential and the working current, the distance between the electrodes, the optimal time of operation, the different support electrolytes and several milk concentrations; the main results were that the ideal combination of electrodes was Al-Fe, connected in parallel using aluminum as sacrificial anode and iron as cathode, with electrode distance of 2 cm and treatment time of 60 minutes. From the evaluation of support electrolytes, the best results were observed using the combination of the two salts with a relation [ ]/ [

of 0.83, because the sample was observed of clarified water and large floccules at about 30 minutes and 44% removal of the COD was determined in 60 minutes; a greater intensity of 380 mA was also obtained, with the following operating conditions; combination of Al-Fe electrodes, electrode distance 2 cm, voltage potential 3V and a cell volume of 600 ml. xvii Formando líderes para la construcción de un nuevo país en paz The treatment is perceived as a good process alternative where the concentrations of were very low, the N2 ammoniacal tends to disappear in time and the COD decreases, in addition there is a good effectiveness of the conductivity, favoring the low energy consumption.
