The inefficiency of conventional methods for removing surfactants and pathogens from wastewater has led to the development of alternative treatments, such as the Fenton process and its variants. In this study, the conventional Fenton process and modified Fenton process with ethylenediaminetetraacetic acid (EDTA) were applied to reduce surfactants and fecal coliforms in rural wastewater in Quito, Ecuador. Under the best experimental conditions, total inactivation of fecal coliforms and a 97% reduction of surfactants and 93% of COD were achieved within 15 minutes of treatment.
