Evaluación del funcionamiento de la planta de tratamiento de aguas residuales del sector Quebrada Callate de la parroquia Presidente Urbina del cantón Santiago de Píllaro de la provincia de Tungurahua

Abstract

In order to evaluate the state of operation of the Callate wastewater treatment plant in the Presidente Urbina parish in the Píllaro canton, inaugurated 6 years ago, it continues to comply with the parameters for the removal of contaminants and pathogens. The evaluation of the WWTP was carried out in 5 stages where information was collected using a documentary method to obtain information on the location, social and economic activity of the sector, the dimensions of the existing treatment units, a volumetric measurement of the inflow and outflow during a period of 30 days and a chemical analysis that evaluated the characteristics of the wastewater. Based on the data obtained, it was diagnosed that the Quebrada Callate sector WWTP currently receives an inflow of 4.67 lts/s, and that all of its treatment train units are well sized. It was evaluated that the plant is not working optimally because the COD and suspended solids parameters exceed the limits established by the TULSMA standard. For this reason, measures were established so that the WWTP can operate effectively. An improvement plan was implemented, including a detailed manual for maintenance and operation, as well as the implementation of an additional wastewater treatment unit and a cover for the sludge drying bed. A reference budget of $20582.60 was obtained for the measures implemented.
