Compte Port, Sergi (Date of defense: 2018-07-03)
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 ...
Ribera Guàrdia, Anna (Date of defense: 2017-12-12)
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 ...
Casas Ruiz, Joan Pere (Date of defense: 2017-05-31)
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 ...
Ferrando Climent, Laura (Date of defense: 2016-11-28)
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 ...
Auguet Horta, Olga (Date of defense: 2016-07-13)
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 ...
Montserrat Royuela, Albert (Date of defense: 2015-07-03)
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 ...
Rodríguez-Caballero, Adrián (Date of defense: 2015-03-20)
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 ...
Aguilera Becker, Rosana (Date of defense: 2015-03-10)
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 ...
Timoner Amer, Xisca (Date of defense: 2014-05-05)
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, ...
