Estandarización del coagulante tipo A en el módulo II de la Planta de Tratamiento de Agua Potable Tixán, mediante la elaboración de una curva de dosificación

Abstract

The objective of this study is to obtain the dosing curve of type A aluminum sulfate coagulant, for module II of the Tixán Drinking Water Treatment Plant. For this process, it was based on obtaining two dosing curves, the first with synthetic water and the second with raw water, made up of optimal dose vs. turbidity. The curves were obtained through statistical analysis in the Microsoft Excel program. In addition, the costs within the coagulation and flocculation process with the two types of aluminum sulfate (A and B) were analyzed, where it was obtained that the operating cost with type A aluminum sulfate coagulant is lower compared to aluminum sulfate. type B aluminum. The sampling, transport and conservation of the raw water samples were carried out under the NTE INEN 2176 and NTE INEN 2169 standards. Due to climatic fluctuations in the city of Cuenca during the months of January, February, March, April and Raw water samples with different turbidity values were taken in May. The synthetic water samples were prepared in the laboratory by mixing raw water with kaolin. The optimal doses of each of the water samples, both for the synthetic and for the raw, were found through jar tests, taking into account the initial and final values of pH, color and turbidity. These tests were developed in the laboratory of Environmental Analysis of the University of Cuenca.
