    Reducción en la demanda bioquímica y química de oxígeno en las aguas residuales de la Tenería Núñez aplicando tratamiento de electrólisis del agua residual
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos y Biotecnología. Carrera de Ingeniería Bioquímica, 2021-09) Vásconez Ortiz, Ricardo Fernando; Pérez Aldas, Lander Vinicio
    The electro-oxidative system with titanium meshed electrodes was studied with the aim of complementing the previous investigation of " Diseño e implementación de la planta de Tratamiento de Aguas Residuales de Tenería Núñez " by Núñez (2021), due to the fact that the methodology created to the treatment of wastewater from the tanning processes was not sufficient to reduce degradability values -by physicochemical methods- until its data allowed by Ecuadorian regulations. The method for oxidative electrolysis of wastewater used a sample of the treated effluent from Tenería Núñez, where in principle initial degradability studies were carried out, focusing on values for Chemical Oxygen Demand and Biochemical Oxygen Demand, as they are the most critical values. compared to the other parameters already reduced. The design of the electrolytic cell and the electro-oxidative methodology were adapted from several authors who have shown to reduce these parameters by up to 99 percent -as in Hernández et. al (2011)- reported in the background of the project; the combination of primary and secondary electrochemical methods (electrocoagulation and electrooxidation) results -in these studies- in an almost total elimination of contaminants and a formidable efficiency. Therefore, avoiding the excessive consumption of resources, the electrolytic oxidation methodology was proposed from titanium electrodes -for its resistance and effectiveness- in short electrolysis times, while considering the low investment for the method (Electricity, electrodes, voltage transformer and circuits). Finally, the post-treatment analysis will decide if the efficiency is acceptable.
