    The evaluation of the Cuicuno neighborhood treatment plant is necessary because the WWTP presents an evident deterioration of the infrastructure, lack of functionality and odor problems, this is a fundamental process to ensure its operational efficiency, regulatory compliance and environmental sustainability. This periodic review will make it possible to identify areas for improvement, optimize processes and guarantee the quality of the treated effluent before it is discharged into the environment. The evaluation began with a detailed analysis of the plant and its infrastructure, including a review of the treatment equipment and systems that make up the WWTP, such as sand traps, biological filters, and septic tanks. Treatment capacity was evaluated based on current and projected demand to ensure that the plant is adequately sized. In addition, the efficiency of the treatment process was analyzed by measuring key parameters, laboratory tests and online monitoring are carried out to assess the performance of the WWTP. The assessment also included an analysis of compliance with local and national environmental standards and regulations. Compliance with various parameters such as BOD, COD, pH and heavy metals were obtained within the results, these results ensure that the effluent does not cause negative impacts on the receiving environment. In conclusion, it was possible to corroborate that the WWTP does work, but only partially. The results of the assessment will provide a roadmap for implementing improvements, ensuring that the plant continues to be a vital part of protecting the environment and public health.

    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2023-03) Barros Manotoa, Klever Leonardo; Morales Fiallos, Fabián Rodrigo
    An inadequate operation of the Wastewater Treatment Plant (PTAR) of the Andahualo community, in the Píllaro canton, causes the environment where the treated water is discharged to become contaminated, putting public health at risk and affecting the flora and fauna. fauna of the sector, it is for this reason that in the present experimental work the operation of the installation was evaluated, to determine if the WWTP purifies the residual water in optimal conditions. Through documentary research, the current status of the WWTP was verified and through field work, the inlet and outlet flow were measured for a month, additionally, samples of residual water from the influent and effluent were taken and sent to a qualified laboratory. For the analysis of the physical-chemical parameters of said samples, the results obtained were compared with the TULSMA 2015 standard. In addition, a technical diagnosis of each stage of treatment of the plant was made, which includes screening grid, sand remover, UASB reactor, upflow biological filters and sludge drying, which made it possible to verify that the treatment plant is in optimal conditions to treat wastewater from the sector. Finally, recommendations were proposed that will allow the plant to improve its operation.

    Evaluación de la planta de tratamiento de aguas residuales de la parroquia Quisapincha, cantón Ambato, provincia de Tungurahua
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2022-09) Toro Silva, Valeria Patricia; Guevara Robalino, Jorge Javier
    In order to determine whether the wastewater treatment plant (WWTP) of the Quisapincha parish is currently working properly or whether its efficiency in the removal of pollutants has been reduced over the years, a survey of information was carried out to measure the units of the treatment train, the volumetric capacity of the plant's inlet and outlet tanks, the analysis of physical-chemical parameters in the laboratory and the technical diagnosis of each process. The operation of the plant's unit processes was evaluated, which are: Screening, sedimentation and flow sharing tank, biological filter of “lechuguines”, upflow anaerobic filter and sludge drying tank, demonstrating that they work correctly in comparison with guides and manuals for the design of treatment plants; and the outflow affluent complies with the TULSMA standard for discharges into freshwater bodies. After analyzing the information, it was concluded that it is not necessary to implement new processes within the WWTP; however, recommendations were proposed for the system to work better.

    Evaluación de la planta de tratamiento de aguas residuales de la comunidad Mochapata, parroquia Yanayacu, cantón Quero, provincia de Tungurahua
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2022-09) Herrera Narváez, Erick Santiago; Silva Tipantasig, Lenin Gabriel
    This experimental work is based on the evaluation of the wastewater treatment plant (WWTP) of the Mochapata community, to determine if the treated water that is discharged into the Mocha River complies with the TULSMA 2015 standard. For this, it began with a survey of information, such as: location, socioeconomic activities of the population and a diagnosis of the treatment units; a field investigation was carried out, where the measurement of the influent and effluent flows was carried out, also a sampling of the residual water inlet and outlet of the WWTP for its subsequent laboratory analysis of its physical and chemical properties. Once the analysis has been carried out, the results obtained are compared with the discharge limits to freshwater, established by the TULSMA standard, where it was determined that six of the ten parameters analyzed do not comply with the regulations, including: oils and fats, biochemical oxygen demand (BOD5), chemical oxygen demand (COD), suspended solids, surfactants, and fecal coliforms. For this reason, it is necessary to look for an alternative to comply with the limits mentioned. The current treatment train was evaluated and, since it did not obtain an acceptable efficiency in the removal of contaminants, it was necessary to propose a new treatment train that guarantees the removal of contaminants below the permissible limits, it is composed of screens, grease trap, septic tank, trickling filter, sludge drying bed and artificial wetland.
