Decision-support for adaptive and sustainable urban wastewater system management in the face of uncertainty
With sustainable development as the new overarching goal, urban wastewater system (UWS) managers are now being asked to take all social, economic, technical and environmental facets related to their decisions into account. ...
Greenhouse gas emissions from wastewater treatment processes: identifying triggering factors at laboratory and full-scale systems
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 ...
Development of new products from aquaculture fish species
Europeans are regular consumers of fish and aquaculture products. Therefore, five species of potential aquaculture rearing named: Meagre, Pikeperch, Grey Mullet, Greater Amberjack and Wreckfish were selected for new product ...
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 ...
Feasibility of incorporating treated lignin and cellulose nanofiber in fiberboards made from corn stalk and rice straw
Agricultural waste is of particularly interest due to abudant, cheap, widely available worldwide and renewable material. It represent a good option for wood sources substitution, containing similar in chemical and physical ...
Endo-β-1,4-glucanasa para la fabricación de micro/nanocelulosa: propiedades y aplicaciones
In the recent years, significant interest on the production, characterization and application of cellulose nanofibers has brought out among scientific and technic authorities. This special attention mainly comes from their ...
Carbon and nitrogen treatment in industrial wastewaters using bioelectrochemical systems
The doctoral thesis has focused on the simultaneous removal of carbon and nitrogen in BES for future application in the treatment of industrial wastewater as swine manure. The bacteria that use the electrode as electron ...
Caracterització del suro i subproductes de la indústria surera. Valoració d'aquests com a biosorbents d'hidrocarburs aromàtics policíclics en aigües d'escorrentia
The main objective of this thesis is to characterize and evaluate the capacity of cork and by-products of the cork industry (collectively called as cork samples) as biosorbents of aqueous polycyclic aromatic hydrocarbons ...
Characterization and improvement of plant-associated Lactobacillus plantarum. Novel biocontrol agent for fire blight disease
Fire blight is a disease caused by Erwinia amylovora. For the limited effectiveness of copper products and the new regulations for the sustainable use of pesticides, biological control is considered a good alternative for ...
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 ...
Conductive nanopaper from cellulose nanofibers and conductive polymers and/or carbon nanotubes
Coming from renewable and sustainable raw materials, nanocelluloses are rapidly emerging as one of the most promising future materials. Recently, the use of nanocellulose nanocomposites in flexible electrodes, biosensors ...
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 ...
Evaluación de las propiedades de materiales compuestos fabricados a partir de fibras semiquímicas de Leucaena collinsii y polipropileno
This thesis studies the effect produced by the reinforcement of polypropylene with a semichemical fibre of Leucaena collinsii in the mechanical, thermal and water uptake properties. Samples with different reinforcement ...
Synthetic antifungal peptides for controlling brown spot of pear caused by Stemphylium vesicarium. Activity, mode of action and field evaluation
Brown spot of pear is a fungal disease caused by Stemphylium vesicarium. Currently, the disease control efficacy is limited, due to the characteristics of disease and the reduction of the allowed fungicides. Therefore, ...
Comprehensive inventories for Life Cycle Assessment in urban wastewater systems
This thesis represents an important contribution to facilitate the efficient creation of detailed inventories to carry out Life Cycle Assessment (LCA) studies of urban wastewater systems. Specifically, this thesis provides ...
Estudi de l'efecte de l'administració de tilosina i doxicilina en els principals paràmetres nutricionals i de composició de l'ou de gallina
The aim of the present work was to study the effects of tylosin A and doxycycline administration to laying hens on egg nutritional and compositional parameters during antibiotic treatment and after a withdrawal period. ...
Fugitive green-house gas emissions during biological wastewater treatment: investigating sources and mitigation strategies in laboratory and full-scale systems
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 ...
