Análisis comparativo del policloruro de aluminio (pac) y sulfato de aluminio líquido (sal) para la optimización del proceso coagulación en la planta de tratamiento de agua potable Francisco Wiesner

Abstract

This study was based on comparing sulfate liquid aluminum in constrast with polyaluminium chloride in the coagulation process with Chingaza, San Rafael and mixed (60% Chingaza 40% San Rafael) samples in the treatment plant potable water Francisco Wiesner located at kilometer 14 of the Bogotá La Calera route. Jar tests were developed to compare optimal doses and physicochemical parameters turbidity, color, pH and residual aluminum between coagulants. In Chingaza the optimal dose of aluminum polychloride was lower than that obtained with aluminum sulfate while in the other sources, the same dose was obtained; parameters turbidity, color and pH PAC was more effective and the residual aluminum was equal for both coagulants materials.
