Rediseño de la Planta de Tratamiento de Agua Potable del sector Yawari del cantón Archidona.

Abstract

The research aimed to redesing the Potable Water Treatment Plant in Yawari area, Archidona-Napo. Proceeding with the physical-chemical and microbiological representation of the water inlet and outlet of the treatment in different weather conditions, in the laboratory of technical analysis in the Science Faculty of the Polytechnic University of Chimborazo. Subsequently, the parameters were determined outside the permissible limits according to the INEN technical standards 1108:2014tosafe drinking water, which have different kind of requirements such as, color, turbidity, iron and phosphates, specifically during the rainy season and the total coliforms and fecal coliforms present all the time. For their removal some testing chemical jar were performed, using the best chemical for the reaction (Aluminium Polychloride, aliminium sulphate), finding the proper dosing with aliminium sufate of 1% and alkalizing (lime) of 1% in order to stabilize the pH of the water. Similarly, the disinfection process was carried out to the treated water to eliminate the presence of coliform. The redesing of the plant was sized by engineering calculations, being; a rectangular overflow with width of 0,50 m a height of 1,20 m, a length of 2,808 m, two hydraulic flocculators with horizontal flow of 15,40 m long and 3,25 m wide, and a sedimentary of high rate that will have 16,5 m long and 3,3 m wide with a retention time of 32 min. The percentages of removal efficiency about the parameters outside of the standard after developing the respective testing of jars disinfection to the treated water which are; color= 99,01%, turbidity= 97,74%, iron= 92,95%, phosphates= 67,21% and microbiological= 100%. Concluding that the implementation of the new processes will improve the water quality, so it is recommended the application of the study in the Municipal GAD of Archidona in order to provide drinking suitable water for consumption by residents.
