Transport, distribution and fate of emerging contaminants in wastewater-receiving rivers under multiple stress conditions
The main aim of this thesis was to establish a link between the urban origin of chemical contamination (e.g. PhACs) and other stressors, particularly associated to water scarcity (Chapter 1, 2, and 3). Research has been ...
Elimination of micropollutants in conventional and novel nitrogen removal processes. A comparative assessment of diverse microbial communities capabilities
Pharmaceutically active compounds (PhACs) and endocrine disrupting compounds (EDCs) can pose a significant risk to the environment and human health, undermining prosperity. Current wastewater treatment plants (WWTPs) cannot ...
Influence of anthropogenic pollution on the prevalence, maintenance and spread of antibiotic resistance in aquatic microbial communities
This Thesis demonstrates that microorganisms derived from wastewater are the 2/2 main contributors to antibiotic resistance (AR) in the environment. Once there, the background chemical contamination with antibiotic ...
Factors affecting the distribution, abundance and diversity of uncultured archaeal groups in freshwater sediments
Archaea are abundant in extreme environments but they are also a prevalent component of microbial communities in soils, marine or freshwater plankton and sediments. Many studies highlighted the prominent role of marine ...
Greenhouse gas emissions from wastewater treatment processes: identifying triggering factors at laboratory and full-scale systems
This thesis focuses on the study of the global green house gas (GHG) emissions from wastewater systems. Nitrous oxide (N2O) and methane (CH4) are the main GHG directly emitted from wastewater treatment plants (WWTP). In ...
Controls on the dynamics of riverine dissolved organic matter: insights from a Mediterranean river network
In river networks, dissolved organic matter (DOM) constitutes the major pool of organic carbon, and plays a key role as energy source and modulator of toxic substances availability. In this thesis, Joan P. Casas-Ruiz and ...
Analysis of chemotherapy drugs and related compounds in aquatic environment: removal, transformation and risk evaluation in eco-friendly and advanced technologies
In order to evaluate the increasing environmental and human risk of anticancer drugs in the environment, more information needs to be gathered about their presence, their toxicity, bioaccumulation and persistence. In ...
Sulfide and methane production in anaerobic sewer pipes: from microbial community characterization to effective mitigation strategies
Sewer systems transport wastewater from its source to treatment plants. During this transport, wastewater microorganisms colonize pipe walls and develop biofilms. The activity of microbial communities generates sulfide ...
Towards better management of combined sewer systems. A methodology based on low-cost monitoring
In combined sewer systems (CSS) wastewater and stormwater flow through the same pipes. During severe rain episodes, the excess combined flow of untreated wastewater and stormwater is released out from the system through ...
Fugitive green-house gas emissions during biological wastewater treatment: investigating sources and mitigation strategies in laboratory and full-scale systems
The exponential increase of the atmospheric concentration of green-house gases due to human activities is responsible for the acceleration of global warming and climate change. Recently, scientific studies have pointed ...
Effects of land uses and climate variability on the water quality of Mediterranean rivers: towards a regional vision of global change
This work investigated the effect of global change phenomena, particularly land use and climatic changes, on water quality patterns in Mediterranean rivers. A hybrid process-based and statistical model (SPARROW) was applied ...
Stream biofilm responses to flow intermittency
Streams experiencing a recurrent non-flow phase (i.e., flow intermittency) are characteristic of world regions with arid and semi-arid climates, where Mediterranean regions are part of. During non-flow streambed sediments, ...
