Los fenómenos ambientales provocan fuerte impacto sobre la variación de la calidad del agua de fuentes de abastecimiento, exigiendo que los procesos de potabilización respondan a tales variaciones y mantengan los estándares de calidad en la producción de agua segura. El análisis histórico del comportamiento de la turbiedad del río Cauca y del agua clarificada y tratada permitió evaluar el efecto del incremento en la turbiedad del agua cruda sobre la eficiencia de los procesos convencionales de potabilización que se realizan en la planta Puerto Mallarino en Cali (Colombia). Se encontró que dicho fenómeno afectó la eficiencia del tratamiento y la calidad del agua tratada, siendo la filtración la etapa más vulnerable. Se identificó alta correlación lineal entre la turbiedad máxima del agua cruda y la dosificación de productos químicos utilizados en el tratamiento del agua (coagulante y desinfectante).
Abstract: Environmental phenomena cause a strong impact in the variation of the quality of sources for drinking water, demanding that potable water treatment processes respond to these changes and maintain quality standards in the production of safe drinking water. The historical analysis of river Cauca turbidity and behavior of clarified and filtrated water allowed evaluating the effect of increase in raw water turbidity over water treatment conventional processes of Puerto Mallarino plant at Cali (Colombia). It was determined that the high turbidity of the water of river affected the treatment efficiency and also the quality of treated water; filtration was the most vulnerable stage to these high turbidity events. A high linear correlation between maximum turbidity and chemical products dose (coagulant and disinfectant) was identified.
