RT Journal Article T1 Disinfection through advance oxidation processes: optimization and application on real wastewater matrices A1 Blanco Canella, Pablo A1 Lama Rodríguez, Gabriela A1 Sanromán Braga, María Ángeles A1 Pazos Currás, Marta María K1 3308.06 Regeneración del Agua K1 2391 Química Ambiental K1 3308 Ingeniería y Tecnología del Medio Ambiente AB Disinfection is an essential and significant process for water treatment to protect the environment and human beings from pathogenic infections. In this study, disinfection through the generation of hydroxyl (Fenton process (FP)) and sulfate (Fenton-like process (FLP)) radicals was validated and optimized. The optimization was carried out in synthetic water through an experimental design methodology using the bacteria Escherichia coli as a model microorganism. Different variables were evaluated in both processes: precursor concentration (peroxymonosulfate (PMS) and H2O2), catalyst concentration (Fe+2), and pH in the Fenton process. After that, the optimized conditions (FP: 132.36 mM H2O2, 0.56 mM Fe+2 and 3.26 pH; FLP: 3.82 mM PMS and 0.40 mM Fe+2) were applied to real matrices from wastewater treatment plants. The obtained results suggest that both processes are promising for disinfection due to the high oxidant power of hydroxyl and sulfate radicals.
