Determinación de la dosis óptima del coagulante sulfato de aluminio aplicado en la planta de tratamiento de agua de la Central Termoeléctrica "El Descanso"

Abstract

This study carried out in the Water Plant of the Hydroelectric Plant "El Descanso", is aimed at determining the optimal dose of coagulant aluminum sulfate type A in accordance with the parameters turbidity, color and pH. By performing jar tests it was determined the optimal dose for each turbidity and develop curve coagulant dosage, it has also made the table of flows of operation depending on the load on the rubbish dump, for along with the curve dosage to obtain the required flow of coagulant.

The purpose of this work is aimed at the use of better quality water at the enterprise level through proper dosage for maximum removal of impurities in the water. For that, it began to take samples of raw water in periods established and perform appropriate tests jars. The waters were studied and analyzed using tables and graphs that helped to better understand the behavior of water. The mixing times and intensities applied in Jar tests were determined experimentally through field and laboratory studies.

The study developed in this work serves to improve the processes of coagulation, flocculation and subsequent processes; it also helps the operator responsible for controlling the processes of the plant to make a correct dosage, avoiding more or less coagulant dose than necessary.
