Abstract
Present study has the aimed to assess the percentage of removal of chemical oxygen demand (COD) of non-biodegradable leachate from the landfill in the city of Loja (Ecuador) to be subjected to a Fenton process. Different concentrations of H<sub>2</sub>O<sub>2</sub> and FeSO<sub>4</sub> were combined in acidic pH values, obtaining removals close to 80% with a concentration of 500 ppm of H<sub>2</sub>O<sub>2</sub> and 1000 ppm of FeSO<sub>4</sub> at pH 4, thus establishing an optimum working radius H<sub>2</sub>O<sub>2</sub>/FeSO<sub>4 </sub>equal to 0.5. Through Box-Behnken statistical analyses were determinates the significant factors, which correspond to the concentration of H<sub>2</sub>O<sub>2</sub> and FeSO<sub>4</sub> employed. With this information the process was optimized, reaching a theoretical removal of 81% at concentrations of 312 ppm of H<sub>2</sub>O<sub>2</sub> and 1087 ppm of FeSO<sub>4</sub> at pH 4. It was observed in this process removal of 79% of turbidity, 33% of Nitrates and 89% of Phosphates.
