En el marco del desarrollo de la pasantía y como parte del trabajo de grado, se ha desarrollado un software libre para el control y seguimiento de los mantenimientos de la Planta de Tratamiento de Agua Residual (PTAR) El Salitre. El software se basa en la información recopilada de los mantenimientos de los equipos electromecánicos de la planta. Por un lado, el software abarca los principales procesos que se llevan a cabo en la PTAR Salitre, como la recolección del agua residual, el tratamiento preliminar, primario, secundario, la desinfección, el tratamiento de lodos y la recuperación de energía a través del biogás. En cuanto al funcionamiento del software, desarrollado en Python, se buscaba mejorar la organización de los documentos relacionados con los mantenimientos, ya que la gestión documental que se ha venido llevando a cabo está generando dificultades en el control, por la magnitud de la información que se maneja en la PTAR. Lo cual, a largo plazo, puede generar impactos negativos en los procesos y operaciones de la planta. Por ejemplo, puede ocasionar la pérdida de rendimiento en la remoción de contaminantes, el aumento del consumo de energía, un mayor riesgo de fallas y tiempos de inactividad no planificados, así como costos significativos de reparación y reemplazo. Por lo tanto, la herramienta desarrollada permite a los operarios ingresar la información obtenida durante los mantenimientos, lo que facilita la detección temprana de equipos que requieren cuidados preventivos o correctivos para prolongar su vida útil. | As part of the development of the internship and as part of the degree work, a free software has been developed for the control and monitoring of the maintenance of the Waste Water Treatment Plant (WWTP) El Salitre. The software is based on the information collected from the maintenance of the electromechanical equipment of the plant. On the one hand, the software covers the main processes carried out at the Salitre WWTP, such as wastewater collection, preliminary, primary and secondary treatment, disinfection, sludge treatment and energy recovery through biogas. Regarding the operation of the software, developed in Python, the aim was to improve the organization of documents related to maintenance, since the document management that has been carried out is generating difficulties in the control, due to the magnitude of the information handled at the WWTP. This, in the long term, can generate negative impacts on the plant's processes and operations. For example, it can cause loss of performance in the removal of pollutants, increased energy consumption, increased risk of failures and unplanned downtime, as well as significant repair and replacement costs. Therefore, the developed tool allows operators to enter the information obtained during maintenance, which facilitates the early detection of equipment that requires preventive or corrective care to prolong its useful life.

International audience | The altitude effect of isotopes in precipitation is not as significant on the leeward side of a mountain as it is on the windward side, which makes it difficult to use isotopes at leeward sites, especially if estimating elevation of groundwater recharge or reconstructing paleoelevations. Samples of precipitation were taken at three stations with different elevations-2,306-3,243 m above mean sea level (asl)-on the leeward side of the Meili Snow Mountains on the southeastern Tibetan Plateau from August 2017 to July 2018. The isotope vs. altitude gradients were calculated based on two adjacent stations at the daily, monthly, and annual scales. Most of the gradients are beyond the global ranges of -0.5 to -0.1 parts per thousand per 100 m for delta O-18 and -5 to -1 parts per thousand per 100 m for delta H-2, and some of the gradients are even positive. Local processes of sub-cloud evaporation and mixing with recycled moisture are identified for the ambiguous altitude effect, while regional atmospheric circulation processes dominate the major patterns of stable isotope variation at the three stations. The groundwater recharge elevation is estimated to be in a very large range, 2,562-6,321 m asl, which could be caused by the differences in isotope vs. altitude gradient in the studied catchments. Considering the complex atmospheric processes affecting precipitation isotopes, sampling of event-based/monthly precipitation at more than two altitudes for at least one complete hydrological year is a minimum requirement to establish a reasonable isotope vs. altitude gradient.
