Resumen

La reacción entre desinfectantes y materia orgánica acuática generan subproductos de desinfección (DBPs). DBPs son motivo de preocupación en el agua potable debido a que causan daños a la salud. Esta investigación busca determinar el efecto de la pre-oxidación con ClO2 en un proceso convencional a escala de laboratorio, sobre la formación de DBPs: trihalometanos (THMs) y ácidos haloacéticos (HAAs). Se realizaron ensayos con agua de un embalse que surte una planta de tratamiento convencional de agua potable, en diferentes épocas climáticas debido a su influencia sobre la naturaleza de la materia orgánica. La aplicación de 0.3 mg/L ClO2 y la dosis de coagulante óptima para remover materia orgánica, arrojó los mejores resultados, 37 μg/L de THMs y 22 μg/L de HAAs, excepto en la época seca. Se encontró que dosis mayores de ClO2 incrementaron los DPBs. Las dosis óptimas de coagulante y de ClO2 deben ser cuidadosamente definidas.
