Diseño de una planta de tratamiento de agua potable para la población del cantón El Tambo, provincia del Cañar

Abstract

The present research is focused on the Designo of The Drinking Water Treatmente Plant for the population of the Cantón El Tambo, Province of Cañar. Which aims to treat wáter from the Culebrillas Lagoon. The type of work carried out was applied and experimental, where the análisis of physical, chemical and microbiological parameters was carried out; obtained from three simples during one quarter, since the established samplimg methodology was fallowed in the NTE-INEN 1108, (2014), and subsequently the results were compared with the máximum permissible limits in the Acuerdo Ministerial No. 097-a, (2015). Based on the results obtained from the aforementioned analyses, it was posible to verify that the parameters in question are within the established limits, so they comply with current environmental regulations. However, BOD5 and COD values are out of norm, this due to external factors such as the presence of cattle on the way from the catchment source to the plant. Finally, through treatability tests corresponding to the jar test, it was determined that the best chemical for the process was Aluminium Sulfate; for the filtration the best type of filter was granular and, for chlorination it was determined that the best desinfectant was Sodium Hypochlorite, respectively. It is worth mentioning that, for the designo of the plant, the desinfectant usea was Chlorine Gas.
