Resumen en inglés | 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 |
