    Evaluación de la planta de tratamiento de aguas residuales del sector El Chilco - La Esperanza del cantón Tisaleo de la provincia de Tungurahua
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-02) Sisa Aguagallo, Alex Gustavo; Moya Medina, Dilon Germán
    The various problems existing in the Treatment Plant such as unpleasant odors, deficiency in the wastewater treatment processes, lack of signage of the units, the excessive growth of unwanted vegetation within the facilities and units of the plant as a result of the lack of maintenance and an operation manual carried out the evaluation of the Wastewater Treatment Plant (WWTP) in the El Chilco – La Esperanza neighborhood of the Tisaleo canton. For the experimental work, it began with the collection of information, the topographic survey and the dimensions of each existing component in the WWTP. The times of highest demand were determined, measuring the inlet and outlet flows of the WWTP, and composite samples of the influent and effluent were collected and then analyzed for physicochemical characteristics in a laboratory to determine water quality parameters. These results were verified with the TULSMA 2015 regulations, revealing that the pH levels are within the range, according to the TULSMA, COD and BOD5 do not meet the efficiency values, so a FAFA is implemented. In addition, an analysis of each hydraulic unit was carried out, and it was concluded that all of them meet the criteria established in the design guidelines and manuals for water treatment facilities. To conclude, proposals are presented that include the incorporation of floating macrophytes in the anaerobic filter that was previously implemented, in addition to a specific operation and maintenance manual for the WWTP
