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, ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
For a long time, there has been a need and an ambition to better understand the behavior of integrated systems by considering the whole urban water cycle, including wastewater transportation, wastewater treatment and the ...
Individual hazardous chemicals and substance mixtures with synergistic toxicity ef-fects occur in the dissolved organic matter (DOM) of wastewater and negatively im-pact human health. Yet a large number of chemicals and ...
The water sector is entering a period of uncertainty, as stressors such as climate change pose unknown risks to its infrastructure. Utilities need to build resilience to handle unpredictable changes, but the field of ...
The presence of several pharmaceutical active compounds (PhACs) in water bodies has garnered increasing attention and worldwide concern. The effluents from wastewater treatment plants (WWTPs) are one of the main sources ...
Forward osmosis (FO) is known to be particularly efficient at treating impaired water sources with a high fouling potential. In the context of water reuse FO is being introduced as a robust pre-treatment process, usually ...
Mediterranean rivers are characterized by high hydrological variability and heterogeneity of habitats, placing themselves amongst arid and temperate climates, and are associated with high biological diversity. On the ...
Human exploitation of river ecosystems, together with the increasing pressure that represents climate change, is posing rivers worldwide at risk. In rivers, microorganisms are ecologically very important. Most of ...
The presence of xenobiotics - such as pharmaceutically active compounds, endocrine disrupting compounds and pesticides - in the aquatic environment has risen great environmental concern due to their high toxicity even at ...
