Hybrid systems for wastewater treatment in the framework of circular economy : coupling biological and membrane technologies for a sustainable water cycle
The increasing water demand coupled to the depletion of natural water sources has raised the need to investigate and develop in wastewater treatment and reuse. Even more, the application of circular economy principies to ...
Sustainable business model perspectives for the electric vehicle industry : the case of battery second use
The purpose of this doctoral research dissertation is to examine sustainable business model (SBM) perspectives for the rapidly developing Battery Second Use (B2U) market within the emerging electric vehicle (EV) industry. ...
Approach to acoustic mapping through continuous mobile monitoring
For the production of representative noise maps, a large amount of information is necessary, which includes, among others, on-site measurements of environmental noise. Thus, for noise maps based on measurements, mobile ...
Advances in life cycle assessment of plastics with mineral fillers in packaging applications
Mineral masterbatches, in other words mineral fillers, are concentrates of calcium carbonate or talc in a polymer base. In addition to their optimal cost, their use improves mechanical properties of materials and reduce ...
Subsurface as a bioreactor : interaction between physical heterogeneity and microbial processes
Infiltration systems are water treatment technologies where water vertically percolates through porous media while several biogeochemical processes occur. Biofilms are the main responsible for those biogeochemical processes ...
Contributions to the determination of thermal behaviour of façades using quantitative internal IRT (Infrared Thermography)
Within the European framework, most of residential buildings do not satisfy the minimum thermal specifications. In fact, the renovation rate across the EU is estimated at 1% per year. To fulfil with the goals stated by ...
Determination of key master variables and radionuclide behavior in the Swedish Final Repository environment
Aquesta tesi doctoral investiga els processos clau que controlen la mobilitat d'alguns dels radionúclids sensibles al redox presents en els residus (U, Pu i Tc) i Ni com a radionúclid crític, en el repositori “Swedish Final ...
Syntrophic acetate oxidation in the anaerobic digestion of nitrogen-rich wastes : from microbial interactions to process optimization
The anaerobic digestion (AD) consists of a cascade of syntrophic interactions between several microbial groups that result in the breakdown of biodegradable organic matter in the absence of oxygen, resulting in the production ...
Strategies to enhance microalgae anaerobic digestion in wastewater treatment systems : pretreatments and co-digestion
Microalgae-based wastewater treatment systems are promising solutions to shift the paradigm from wastewater treatment to energy and resources recovery. In these systems, microalgae assimilate nutrients and produce oxygen ...
Production of carbohydrates and polyhydrohybutyrate by cyanobacteria grown in wastewater
Cyanobacteria are prokaryotic aerobic photosynthetic microorganisms with the capacity to remove nutrients from wastewater and synthesize a large variety of bioactive compounds and valuable byproducts. Among those valuable ...
Assessment of dynamic aerosol-radiation interaction in atmospheric models
In this thesis an assessment of the parameterization of the Aerosol-Radiation Interaction (ARI) in online integrated meteorology-chemistry models has been conducted. The model estimates of ARI radiative effects are still ...
Study of near field processes involved in the oxidative dissolution of the spent nuclear fuel and radionuclides release
Nowadays nuclear power plants (NPP) and dedicated facilities are storing the spent nuclear fuel (SNF). In the case of Spain, the NPP have enough space in their pools to keep storing the SNF produced from their activity; ...
Productos de cuidado personal en el medio ambiente : presencia, destino y efectos
In this PhD. Thesis the results of eleven studies about the presence, distribution, and effects of personal care products (PCPs) in the environment are presented with the intention of giving a consolidated vision and to ...
Contaminants orgànics persistents i pseudopersistents en medi marí : estudi en biota i en consum humà
During the last couple of decades the demand for good quality water in sufficient quantity has increased. The administration is now aware that water is not a commercial product; that hydrological management needs to be ...
Modeling the dust life cycle and its associated meteorological processes from global to regional scales
This thesis aims to test the ability of a non-hydrostatic multiscale mineral dust model to reproduce the physical processes associated with the dust cycle at meteorological scales ranging from synoptic to mesoscale (~100-1 ...
Aplicación de MALDI-TOF Imaging y HPLC-MS/MS al estudio de la degradación del polímero policaprolactonadiol en diferentes medios acuáticos
Water is essential for life, human activities and ecosystems. The global climate change together the population increase causes an imbalance between the demand of water and the available water resources.. All these factors ...
Constructed wetland microbial fuel cells : electricity generation, treatment efficiency improvement, COD bioindication and clogging assessment
Horizontal Subsurface Flow Constructed Wetlands (HSSF CWs) are natural wastewater treatment systems showing a marked redox gradient between the surface of the system and the bottom zone of the treatment bed. Therefore, ...
A downscaling methodology for microscale wind modelling and forecasting
Near-surface wind fields are typically obtained from mesoscale Numerical Weather Prediction (NWP) models. These models describe the physics and dynamics of atmospheric phenomena with characteristic dimensions spanning from ...
Analysis of the aerosol-radiation-cloud interactions through the use of regional climate/chemistry coupled models
The response of the climate systems to aerosols and their effect on the radiative budget of the Earth is the most uncertain climate feedback and one of the key topics in climate change mitigation. Air quality-climate studies ...
On-line coupling of volcanic ash and aerosols transport with global and regional meteorological models
Explosive volcanic eruptions can eject large quantities of particulate matter that, along with other aerosol droplets and trace gases, are carried upwards into the atmosphere by the buoyant eruption column and then dispersed ...
