Item 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 WilfridoIn 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.
