dc.description | The reaction between disinfectants and aquatic organic matter generate disinfection by-products (DBPs). DBPs are of concern in the drinking water because they cause damage to health. This investigation aims to determine the effect of treatment of pre-oxidation with ClO2, in a conventional process at laboratory scale, on the formation of the DBPs: trihalomethanes (THMs) and haloacetic acids (HAAs). Trials were performed with water from a reservoir that supplies a drinking water conventional treatment plant during different climatic periods due to its influence on the nature of the organic matter. Applying 0.3 mg/L ClO2 and the optimal dose of coagulant to remove organic matter, gave the best results, 37 μg/L of THMs and 22 μg/L of HAAs, except in the dry season. It was found that higher doses of ClO2 increased DPBs. The optimal doses of coagulant and of ClO2 must be carefully defined. | en-US |

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. | es-ES |
