    Mass transport and fouling of novel forward osmosis thin-film composite membranes 

    Sauchelli Toran, Marc (Date of defense: 2019-07-18)

    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 ...

    Multiple stressor effects on river biofilm communities: from community composition to ecosystem processes using experimental mesocosms 

    Romero Blanch, Ferran (Date of defense: 2019-12-20)

    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 ...

    Removal of pharmaceuticals in wastewater combining different treatment technologies: suspect screening identification and risk assessment of transformation products 

    Jaén Gil, Adrián (Date of defense: 2021-05-28)

    The low efficiency of wastewater treatment plants to achieve the complete removal of micropollutants, including pharmaceuticals, has motivated the development of alternative water technologies to improve their efficiency, ...

    Resilience of water resource recovery facilities: a framework for quantitative model-based assessment 

    Juan García, Pau (Date of defense: 2019-02-04)

    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 ...

    Stream biofilm responses to flow intermittency 

    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, ...

    Sulfide and methane production in anaerobic sewer pipes: from microbial community characterization to effective mitigation strategies 

    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 ...

    Target analysis and suspect screening of wastewater derived contaminants in receiving riverine and coastal areas and assessment of environmental risks 

    Čelić, Mira (Date of defense: 2020-12-15)

    The main objective of this thesis is to evaluate the impact of wastewater discharges on receiving riverine and coastal ecosystems by studying the occurrence and fate of emerging contaminants (ECs). Since there is a myriad ...

    Towards better management of combined sewer systems. A methodology based on low-cost monitoring 

    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 ...

    Transport, distribution and fate of emerging contaminants in wastewater-receiving rivers under multiple stress conditions 

    Mandarić, Ladislav (Date of defense: 2018-10-24)

    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 ...
