    Evaluación del funcionamiento de la planta de tratamiento de aguas residuales del sector Tres Esquinas de la parroquia Presidente Urbina, perteneciente al cantón Santiago de Píllaro, provincia de Tungurahua

    At present, a serious environmental impact has been observed due to the discharge of wastewater without prior treatment or without adequate sanitation, in order to know if the wastewater treatment plant (PTAR) in the Tres Esquinas sector currently works correctly or has reduced its efficiency in the removal of contaminants, an information survey was carried out in the field, where the maximum flow rates at the entrance and exit of the plant were determined, resulting in 2.40 liters/sec in the tributary and 2.02 liters/sec in the effluent, and thus obtain residual water samples for subsequent laboratory analysis. With the laboratory results and their respective dimensions, the operation of the plant components was evaluated, which are: flow distribution tank, septic tank, ascending flow anaerobic filter (FAFA) and sludge drying bed, demonstrating in mostly the correct operation of the WWTP compared to design manuals; adding that the values of the parameters of the wastewater effluent are less than the maximum values stipulated in the TULSMA 2015 standard. As a result, and to improve the performance of the WWTP, a resizing of the septic tank is proposed, the only component that did not comply with the sizing based on the RAS 2000 standard, additionally an operation and maintenance plan for it is presented, the design of an enclosure and a cover for the sludge drying bed with their respective plans and referential budget.
