Integrating computational fluid dynamics and biological model to assess wastewater reactor design
This doctoral thesis has integrated biological models (activated sludge models “ASM”) with simulation tools of computational fluid dynamics “CFD”, and has applied them to the design of two advanced technologies for wastewater ...
Sistema d'ajut a la decisió per la selecció de sistemes de sanejament
The selection of the most appropriate wastewater treatment involves a complex decision making process. For that reason, some tools have been developed in recent years in order to deal with this complexity, as Novedar_EDSS ...
Paisatges de frontera dels territoris de pas dels Pirineus: els casos de l’àrea central de l’Espai Català Transfronterer i l’àrea central de l’Eurociutat Basca
Border landscapes often constitute geographical unities which have experimented distinct landscapes dynamics in each side of the border. This fact occurs because these border landscapes belong to different countries. The ...
Canvis recents en el consum i la gestió de l'aigua en espais turístics. El cas de la Costa Brava (Girona)
Tourism has become one of the most important economic sectors in the Mediterranean coast. Despite the economic benefits generated by tourism at local and regional level, the environmental impacts related to water consumption ...
Siloxane removal in the energy recovery of biogas: sequential adsorption/oxidation processes
The thesis deals with removal of organosilicon compounds in the energy recovery of biogas. Alternative adsorbents for the siloxane removal were studied, and the physical and chemical mechanisms involved in the siloxane ...
Bioelectrochemical transformation of carbon dioxide to target compounds through microbial electrosynthesis
In 2015 the average concentration of CO2 in the atmosphere exceeded 400 ppm. Some technologies, including CO2 capture and storage, are palliative. However, the development of alternatives to burning of fossil fuels focuses ...
Cultura campesina, cambio técnico y medio ambiente en el consejo popular "Cuatro Esquina" de Santa Lucía
The research subject comes as a result of the need to implement sustainable practices in agriculture, in order to confront the environmental deterioration. The research aspires to explain the relation between peasant ...
Diagnóstico y pronóstico de emisión de gases de efecto invernadero de la provincia de Matanzas
A detailed inventory of GHG based on the year 2002 was developed as part of the initial diagnosis of the emission of greenhouse gases (GHG) in the Province of Matanzas. This inventory was the first of provincial level ...
Insights into key parameters for bio-alcohol production in syngas fermentation using model carboxydotrophic bacteria
This doctoral thesis deals with the synthesis of two biofuels (bioethanol and biobuthanol) by bacteria. Concretely, the thesis is focused on a group of bacteria able to grow in a simple substrate such as synthesis gas or ...
Valoración de los atributos y las preferencias paisajísticas en la gestión turística de las áreas naturales protegidas: el caso de Chihuahua, México
El paisaje se ha considerado un elemento fundamental en la preferencia para visitar espacios naturales, con alto valor ecológico y paisajístico, con el propósito de realizar actividades turísticas y recreativas. Esta tesis ...
Green citites and green urban economy; contributions from case studies for a necessary low-carbon future
City Governments engaged in climate change mitigation and adaptation face the multiple challenge of self-commitment, the need to involve their communities and stakeholders, and top-down and multi-scalar processes out of ...
Bioremediation of nitrate-polluted groundwater using bioelectrochemical systems
The presence of nitrates (NO3-) in groundwater is a worldwide concern. The high energy demand and environmental impact of available technologies requires investigating new technologies. This thesis was focused on investigating ...
Vers una gestió territorial del regadiu. Model i aplicació a tres casos d'estudi de l'Europa meridional
La tesi doctoral "Vers una gestió territorial del regadiu. Model i aplicació a tres casos d’estudi de l’Europa meridional" aprofundeix en la gestió del regadiu des d’una perspectiva territorial, tot definint i aplicant el ...
Integrated operation of membrane bioreactors: simulation and experimental studies
Membrane bioreactors (MBR) are a combination of common bioreactors and membrane filtration units for biomass retention, presenting unique advantages like high effluent quality and a smaller footprint than the one by ...
Effects of operational conditions on the performance of a partial nitritation SBR treating high nitrogen loads
The biological treatment of industrial wastewater containing high nitrogen concentrations (>1000 mg N L-1) and low biodegradable organic matter (bCOD) such as landfill leachate is nowadays challenging. Conventional ...
Minimisation and abatement of volatile sulphur compounds in sewage sludge processing
Environmental pollution related to odour emission has become in the last years an important public concern. Closeness of odour-causing facilities such as waste water treatment plants (WWTPs) to urban areas further aggravates ...
Diagnosis, assessment and optimisation of the design and operation of municipal MBRs
This thesis is based on diagnosing, assessing and optimising the design and operation of membrane bioreactors (MBR) used for treating municipal wastewater. Specifically, this thesis has been carried out within the framework ...
Multi-scale investigation of occurrence, fate, removal and biodegradation of pharmaceutical contamination in wastewater treatment and river systems
Human and veterinary pharmaceuticals have been recognized as ubiquitous water microcontaminants with potential subtle detrimental effects on aquatic organisms. The majority of pharmaceutical compounds, after being consumed ...
Coordinated management of urban wastewater systems by means of advanced environmental decision support systems
In the last decades and due to the Water Framework Directive implementation, the urban wastewater cycle management has become more complex. The concept of integrated urban wastewater system management is introduced, and ...
Development of an environmental decision support system for the selection and integrated assessment of process flow diagrams in wastewater treatment
The wastewater treatment plays an important role in the maintenance of natural water resources. However, regardless of the technology used or the level of treatment required, the treatment plants of the XXI century are ...
