Resumen o descripción

In this study electrochemical treatment of dairy industry wastewater, generated ice cream manufacturing was studied using a combined system comprising of electrocoagulation (EC), Fenton reaction and ozone processing. Dairy industry wastewater is characterized by high biochemical oxygen demand (BOD5), chemical oxygen demand (COD), and other pollutants. The objective of this research was to investigate the effects of the operating parameters such as: applied current density (j), reaction time, hydrogen peroxide (H2O2), iron (Fe2+) and ozone dosage as a wastewater treatment method. For this propose rectangular aluminum anodes and iron cathodes were used in parallel within an electrochemical device. Electrocoagulation is efficient and able to achieve a 40% COD removal at a current density (j) of 5 mA/cm2, the addition of a Fenton process to the electrocoagulation further increases the treatment efficiency close to 25% in at a ratio 1:1 H2O2/Fe2+. When used in combination with ozone promotional system further contributes an additional 30% COD removal. These results demonstrate the viability of coupled electrocoagulation with advance oxidation process processing as a reliable technique for removal of pollutants from ice cream manufacturing wastewater.
