    Evaluación de la planta de tratamiento de aguas residuales de la comunidad Mochapata, parroquia Yanayacu, cantón Quero, provincia de Tungurahua

    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.

    Evaluación de la planta de tratamiento de aguas residuales de la parroquia San Andrés, cantón Píllaro provincia Tungurahua
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2022-03) Tamay Chiluiza, Karina Belén; Núñez Aldás, Galo Wilfrido
    In the present experimental work, the evaluation was carried out in order to determine if the treated water that is discharged into the river complies with the TULSMA 2015 standard, which is why it began with the gathering of the information of the entire sector where the PTAR; Data collection on the effluent and effluent flows was carried out, the residual water was sampled at the entry and exit points to the PTAR for the analysis of the physical-chemical characteristics that were processed in a laboratory. Subsequently, a comparison was made with the water discharge parameters established by TULSMA 2015 where it was possible to verify that the Biochemical Oxygen Demand (DBO) and the Chemical Oxygen Demand (DQO) do not comply with the provisions of current regulations, for so it was decided to look for a proposal that would allow to improve the mentioned parameters. With the results obtained, an analysis was carried out according to the degree of actual removal to perform a recalculation of its geometric properties in order to give a definitive diagnosis of the current state of the PTAR and it was found that they allow to improve the BOD and COD of the water treated before final discharge, which includes: screening, sand trap, inhoff tank, trickling filter, fafa, sludge drying bed and a disinfection plant. Additionally, an operation and maintenance plan was implemented that efficiently fulfills the purpose for which said PTAR was designed.

    Mejoramiento del sistema de abastecimiento de agua potable para mejorar la calidad de vida de la comunidad las Peñas, perteneciente a la parroquia Veracruz, cantón Pastaza, provincia de Pastaza
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2022-03) Medina Pico, Luis Fernando; Núñez Aldás, Galo Wilfrido
    In the present project in which the evaluation of the existing drinking water system was first carried out through observation sheets where it was concluded that the construction of a new drinking water system was necessary because the current one was found in terrible conditions. The topographical survey of the sector was carried out to obtain the profile, which indicated where the pipe should be placed and what would be the dimensions that it will need to resist the pressures and speeds to which it will be subjected. An intake with reinforced concrete walls was designed, the same one that was modeled in a specialized software for design, the overturning and sliding checks were carried out. A purification system was designed that has a settler, a filter and a chlorinator, which discharges into the storage tank that was designed and modeled in specialized software respecting the Ecuadorian Construction Standard.
