Propuesta de un sistema de potabilización para la comunidad Unión y Progreso, cantón Cotacachi, provincia de Imbabura

Abstract

Limited access to basic services is common in Ecuadorian rural areas, where drinking water coverage covers less than half the population, it is imperative to implement effective drinking water processes at an affordable cost. Unión y Progreso, a rural community of scarce economic resources located in the Cotacachi canton, province of Imbabura, does not have a potable water supply and supplies itself with groundwater through a well, the quality of which is unknown and lacks treatment. This investigation analyzed 23 biological, physical and chemical parameters of the groundwater of the community well, comparing the results with the standards: INEN 1108 and Annex I, book VI of the TULSMA, finding disagreements in turbidity, color, iron and manganese. Subsequently, a purification process was designed for the elimination of nonconformities, taking advantage of the resources and buildings of the community under the criteria established for the case. The proposed system operates under gravity and contemplates an ideal aeration phase to remove 80% of iron and manganese, followed by an ideal filtration stage to

remove more than 95% of color, turbidity, iron and manganese, and concludes with the phase of disinfection by applying sodium hypochlorite.
