Diseño de un sistema de tratamiento de agua potable para la parroquia San Isidro del cantón Guano

Abstract

The design of a drinking water treatment system for the San Isidro parish of the Guano canton was carried out, which will improve the quality of life of its population. For the development of this research, simple sampling was carried out, with a weekly sampling in the water catchment, for a period of one month, after which, the analysis was carried out in the laboratory of Technical Analysis of the Faculty of Sciences of the ESPOCH. The results of the analyses were tabulated in a spreadsheet, which helped to identify the process variables. In addition, a water supply of 120 L/h/d was considered, for a total of 10735 inhabitants projected for 20 years, with a flow of 20.34 L/s. With these values, the drinking water treatment system was designed, determining that a catchment tank and a storage tank of 12.2 m3 each, a multiple tray aerator with 4 towers of 2 meters high and 3 trays each, are needed. The filter will contain zeolite as filter media and its volume of 40 L, a chlorination tank of 18.3 m3; this system was validated by means of a zeolite composite filter at laboratory level, reaching an efficiency of 89 % and a yield of 96 %. This treatment system, designed for drinking water purification, will guarantee drinking water quality in accordance with NTE INEN 1108.
