Comparación de los procesos de tratamiento de agua en las plantas Uchupucún Y Mahuarcay de la ciudad de Azogues

Abstract

The present investigation is a comparative study of the purification processes of two conventional water treatment plants "Uchupucún" and "Mahuarcay" of the city of Azogues through the analysis of physical parameters (turbidity, conductivity and total solids) and Microbiological parameters (total coliforms and fecal coliforms). For the analysis of the different parameters, techniques established in national and international regulations were used. The determination of turbidity was made in the HACH 2100 AN USA equipment, conductivity and total solids were analyzed in the HACH - CONDUCTIVITY / TDS METER USA equipment. Total and fecal coliform counts were determined by the Colilert® method. In total, 120 samples distributed over a period of seven weeks were analyzed; each week 3 samples were taken on Mondays, Wednesdays and Thursdays from each study point of each treatment plant. The results were statistically evaluated using two-tailed Student's t-tests using a significance level of 5%. Only incoming or raw water presented statistically significant differences in the conductivity (<0.001) and total (<0.001) measurements, which may be due to the different flow rates that feed the plants. The other stages analyzed in both physical and microbiological parameters did not present statistically significant differences, demonstrating that the treatment process of these two plants that supply the highest percentage of the population is statistically comparable.
