Valoración de la Planta de Tratamiento de Aguas Residuales PTAR del Campus de la Universidad Santo Tomás, e Identificación de Alternativas de Reúso en Actividades de Riego y Sanitarios.

Abstract

This paper focuses on the evaluation and possible improvement of the operation of the wastewater treatment plant (WWTP), at the Santo Tomás University campus, which currently has an average flow of 4.46 lps and serves an estimated population of 1,000 to 1,400 people; This with the aim of proposing a theoretical system that allows the recirculation of domestic wastewater towards irrigation activities and use in sanitary facilities. To achieve this objective, a diagnosis of the WWTP was carried out by taking composite and punctual samples at the different stages of the plant. presenting values below the maximum permissible values established in resolution 1076 of 2015, 1256 of 2021 and the Mexican regulation NOM-003-ECOL-1997, In addition to a removal range between 90% and 95% of BOD, COD, greases and oils. This demonstrates the capacity to reuse treated water for sanitary purposes since it generates a theoretical saving of 2 million per month But for the theoretical case of irrigation, it cannot be considered a viable idea because its return on investment is very long term.
