The activated sludge and anaerobic digestion processes have been modelled in widely accepted models. Nevertheless, these models still have limitations when describing operational problems of microbiological origin. The aim ...
Nowadays the problem of climate change on planet Earth has aggravated, it has become extremely important to find solutions that considerably reduce or even eliminate its causes. Among the set of solutions that have been ...
The main goal of this thesis is the production and characterization of composites materials from a bio-based polyamide and natural fibres which could be more sustainable alternative to glass fibre reinforced polypropylene. ...
La demanda creixent de productes mínimament processats i llestos per al consum planteja un important repte per a la seguretat alimentaria i ha conduit al desenvolupament de tractaments suaus que permetin inhibir el creixement ...
A new technology for Cr(VI) and divalent metal ions removal based on metal sorption onto exhausted coffee waste has been developed. Physical and chemical characterization of exhausted coffee waste was explored as well as ...
La present tesi proposa una metodologia de disseny conceptual d'estacions depuradores d'aigües residuals (EDAR) mitjançant la combinació del procés de decisió jeràrquic i l'anàlisi de decisions multicriteri. El document ...
La presente tesis realizó el análisis y evaluación de los métodos estadísticos para valorar la calidad del café. En este sentido, se dio un aporte para tratar de cuantificar y cualificar la calidad del café mediante las ...
Se introdujeron varias modificaciones tecnológicas en la elaboración habitual del jamón curado español de cerdo blanco para mejorar su seguridad y calidad, así como para investigar la contribución relativa de los diversos ...
In recent years, several studies have linked sodium intake to hypertension, and the consequent mortality risk due to vascular diseases. Several UE member states and the WHO recommend reducing the salt intake level to a ...
El treball que s'ha dut a terme es centra en la recerca d'agents modificants per a fibres cel·lulòsiques capaços de reduir la polaritat de les funcions alcohol de la seva estructura per formació de funcions ester. Les ...
As a renewable alternative to petroleum-based materials, wood or plant-based materials offer a greater prospect in the transition towards sustainable replacements. Native to wood, cellulose nanofibers (CNF) form the major ...
Bio and nano technologies are absent or incipient in papermaking industry and, concretely, in recycling and high-yield pulps sectors. In this sense, the present Thesis uses cellulose nanofibers (CNF), both in bulk and on ...
In the last decades, the awareness of environmental issues has increased in society considerably. There is an increasing need to improve the effluent quality of domestic wastewater treatment processes. This thesis describes ...
Anammox-based processes have been commonly applied for the treatment of reject water (high nitrogen content and low C:N ratio), in the sidestream line of urban wastewater tretament plants (WWTP). However, in recent years, ...
To achieve a sand filter design that reduce its pressure loss, computational fluid dynamics (CFD) tecnique was used combined with laboratory tests in a scaled filter using different filter media. The CFD models allowed to ...
Els lixiviats d'abocadors urbans són aigües residuals altament contaminades, que es caracteritzen per les elevades concentracions d'amoni i el baix contingut de matèria orgànica biodegradable. El tractament dels lixiviats ...
La tesi doctoral que es presenta a continuació té com a objectiu estudiar la percepció que tenen els consumidors espanyols del peix d’aqüicultura en comparació amb el peix salvatge, des de vàries perspectives: percepció ...
This thesis evaluates different technologies for treating wastewater with high concentrations of PPCPs. Firstly, a state-of-art revision of advanced treatment technology for removing Triclosan (TCS) from waste water was ...
In the present work, a study of the preparation of new formulations of acrylic bone cements (ABC) has been carried, to obtain materials with capacity for controlled drug delivery of medicaments useful in the therapeutic ...
Volatile Organic Compounds (VOCs) are one of the main groups of odour causing compounds in Waste Water Treatment Plants (WWTP). Adsorption technology is already established, in recent years the interest for the optimization ...
