Texto completo da fonteLos depósitos de sedimentos en sistemas unitarios de alcantarillado pueden dar lugar a importantes problemas de calidad de aguas, muchas veces ignorados. La acumulación de sedimentos en estos sistemas puede generar el aumento en la frecuencia de vertidos a medios naturales receptores durante una tormenta. La presencia de sólidos de origen orgánico en los vertidos de aguas sin tratar puede producir impactos perjudiciales en las aguas receptoras. Los medioambientes acuáticos son afectados principalmente por las altas demandas de oxígeno y las contribuciones de nitrógeno originados en los sedimentos orgánicos. Este estudio se centra en los procesos de re-suspensión de sedimentos altamente orgánicos que se han acumulado en las redes de alcantarillado unitario. Luego de largos períodos secos típicos en la región Mediterránea, los depósitos de sedimentos son re-movilizados y transportados a través del sistema por la escorrentía producida por una tormenta. El objetivo de la investigación es desarrollar una metodología que sea capaz de predecir el potencial de erosión y posterior movilización de los sedimentos orgánicos a través del sistema. Para ello, es necesario mejorar el conocimiento que se tiene sobre los procesos que ocurren durante largos períodos sin lluvias y analizar las variables involucradas que puedan influir en la erosión de los depósitos. Contar con la disponibilidad de datos de campo confiables es esencial en el logro de resultados válido en un modelo de calidad de aguas. Muestras de sedimento no homogéneo y altamente orgánico se recogieron en un sistema de alcantarillado unitario. A través de ensayos en laboratorio, estos sedimentos se utilizaron para la evaluación de sus características y comportamiento vinculado a la erosión. La introducción en el modelo de una ley de tensión crítica de arrastre más realista permite una mejor representación de la movilización de los sedimentos. Los resultados obtenidos muestran que la predicción del transporte de sedimentos orgánicos de alcantarillado es posible de realizar aunque es un tema muy complejo. Mayores esfuerzos son aún necesarios para lograr la transferencia directa de los resultados para una aplicación más generalizada del modelo predictivo obtenido. Una de las principales contribuciones de esta investigación está vinculada al logro de un conocimiento más detallado de la estructura de los depósitos de sedimento orgánico en relación a su resistencia a la erosión. El conocimiento adquirido podría ser aplicado en la mejora en las predicciones de cargas contaminantes que llegan a cursos de agua naturales durante vertidos. Todo ello, siguiendo como objetivo final, la protección de las aguas naturales receptoras.

Texto completo da fonteThe present work studies the sediment erosion in combined sewers. For this purpose, an in-situ instrument was developed, constructed and calibrated. For the first time, such an instrument was used to perform erosion measurements on real, undisturbed sewer sediments on a large scale. In the analysis, the bottom shear stress was used as an indicator for the sediment stability applying established methods and also a newly developed one. The sediments in the investigated sewer show a distinct cohesive erosion behavior. Hence, they behave similar to sediments in natural waters. Therefore, one can with some limitations use the extensive experience in the field of marine, estuarine, and fluvial sediments. The influences studied in that field were evaluated according to their relevance for sewer sediments in a extensive literature research. Due to the large number of influence factors in addition to their interactions, this topic is very complex and the actual erosion behavior difficult to predict. Hence, in-situ studies are a essential foundation for the development of a general model for sediment erosion

Texto completo da fontePlastics have become an integral part of modern human life. Alongside urbanization, metropolitan areas have become hotspots of plastic consumption and disposal. The abundance of microplastics (MPs) in urban wastewater reflects plastic pollution issue in these regions. Since the potential impacts of MPs on humans and ecosystems are of great concern, understanding their pathway in the environment is crucial to support the implementation for mitigation measures. In this context, this PhD project focused on the occurrence and fate of MPs in the Parisian wastewater management system, aiming to investigate and assess potential ways in which MPs from urban areas are released into the surrounding environments.In wastewater treatment plants (WWTPs), MPs separated from water phase are transferred into sewage sludge, making this byproduct a plausible source of MPs when disposed of in the environment. Knowledge of MPs in sewage sludge is essential for gaining a comprehensive understanding of this pollutant within WWTPs and its potential emission from these facilities. By investigating MPs at different sludge treatment stages, the study found that current technologies were inefficient in completely removing MPs. There was no significant reduction in MP abundance observed after all treatment processes, with 8.6×104 to 4.5×105 particles/kg of MPs remaining in the final treated sludge. Some sludge-based MPs were returned back to the system via reject water. Thermal treatment at high temperatures induced the fragmentation of plastic particles. These findings imply sludge disposal as an input of MPs into the environment, for example, via soil application in agricultural land.While MPs in WWTPs have been intensively investigated in the last decade, little attention has been paid for their fate and occurrence during transport within the sewer network before reaching treatment facilities. To address this knowledge gap, an investigation into MPs in sewer sediments, which act as pollutant reserve inside the sewer system, were carried out. The findings indicated that a portion of MPs was temporarily stored in sewer sediments instead of being transported to WWTPs. High concentrations of MPs, ranging from 5×103 to 178×103 particles/kg, were found in these sediments. This highlights a major stock of MPs inside the sewer network and the associated risk of downstream transfer during wet weather events due to the resuspension of in-sewer sediments.Receiving pollutants, including MPs, from various sources such as households, runoff and also the remobilization of in-sewer deposits, combined sewer overflows (CSOs) are expected to release a large amount of MPs into receiving waters. However, research on this emission pathway is still limited. Therefore, a study to evaluate the quality of CSOs in terms of MP contamination and their potential to emit MPs into the environment was carried out. High MP levels were detected in CSOs during different storm events, ranging from 6.7×104 to 3.9×105 particles/m3. At an annual scale, the amount of MPs released with CSOs was equivalent to the massive load from treated wastewater, despite much lower discharge volumes. Thus, these findings confirmed the significant role of CSOs as a land-based source of MPs into the surrounding environment during intense wet weather events.In conclusion, this PhD project has provided data on MP contamination levels in various compartments of the wastewater management system. It has also contributed to the understanding of the different pathways in which MPs are released from the system into the environment. This study emphasizes inadequacy of existing management systems in addressing plastic pollution. Therefore, it calls for urgent actions to mitigate the impact of urban wastewater on nearby water bodies in terms of plastic pollution

Texto completo da fonteDespite their disappointing performance, urban stormwater quality models are still considered to be a potentially efficient decision making tool to control combined sewer overflows (CSOs) and thus are receiving ongoing investments to improve their quality. In this respect, in-sewer sediments are now widely recognized for their preponderant contribution to the pollution of CSOs assigning therefore a particular importance to mastering sewer processes module when refining these models. Recent studies conducted on in-sewer sediments in one of the extensively investigated urban catchments in Paris, Le Marais, highlighted new elements that could be helpful when addressing this module: (1) the existence of quasi-steady sewer grits deforming sewer characteristics and thus suspected to modify sewer flow conditions; (2) the identification of the potentially eroded sediment type during wet weather that is formed at the upstream parts of the Marais main trunks, the organic layer, that showed a cohesive like characteristic during in-situ flushing experiments. A site specific model for the Marais catchment is developed in this thesis adopting a semi-distributed configuration to examine the effect of integrating these field observations in its structure on the simulation of outfall discharges’ quality.In the first part, an evaluation of the impact of considering the sewer grits in the hydrodynamic module on the solid production and transfer processes in sewer system was carried out. To do so, a special modelling tool was necessary in order to handle sewer flow over a complex bathymetry. So, a well-balanced Godunov numerical scheme was developed and verified against some reference test cases before being extended to the Marais sewer scale. Results showed a significant impact of these coarse deposits on the hydraulic parameters. Solid production was demonstrated to be more sensible to this impact than the transfer processes.In the second place, previous findings obtained on combined sewer systems having no organic layer and high sewer contribution along with those obtained on the Marais were deeply investigated to identify the real role of this organic layer in sewer wet weather production. Results showed that this latter is only a minor source for wet weather erosion. To identify the major source, a quality module based on Skipworth erosion formulation and simple advection equation was used to test several scenarios of sewer sediment localization. The benchmark confirmed that the organic layer is not the major source of sewer production and that another source is preponderant and that can be located at the upstream branches as well as along the principal collectors with more probability of the former case
