Reducing chemical risk in raw water from the River Cauca (caused by the presence of pentachlorophenol and organic matter (real color, UV254 absorbance)) was evaluated at bench scale by using three treatment sequences: adsorption with powdered activated coal (PAC); adsorption – coagulation; and, adsorption – disinfection – coagulation. The results showed that although PAC is appropriate for pentachlorophenol removal, and its use together with the coagulant (aluminium sulphate) significantly improved phenolic compound and organic matter removal (promoting enhanced coagulation), the most efficient treatment sequence was adsorption – disinfection - coagulation, achieving minor pentachlorophenol levels than detection (1.56 μg/l) and WHO limits (9μg/l) due to the effect of chloride on PAC.
La reducción del riesgo químico del agua cruda del río Cauca causado por la presencia de pentaclorofenol y materia orgánica (color real, absorbancia UV254) se evaluó a escala de laboratorio mediante tres secuencias de tratamiento: adsorción con carbón activado en polvo (CAP); adsorción–coagulación y adsorción–desinfección-coagulación. Los resultados mostraron que el CAP es un compuesto adecuado para la remoción del pentaclorofenol y que su uso conjunto con el coagulante (sulfato de aluminio) mejora significativamente la remoción tanto del compuesto fenólico como de la materia orgánica, promoviendo la coagulación mejorada; sin embargo, la secuencia de tratamiento más eficiente fue la de adsorción–desinfección–coagulación, alcanzándose niveles de pentaclorofenol inferiores al límite de detección (1,56 μg/l), valor menor que el límite de 9μg/l establecido por la OMS debido al efecto del cloro sobre el CAP.
