Solar disinfection of secondary effluent and the subsequent bacterial regrowth : considerations, limitations and environmental perspectives
The present Thesis deals with the solar disinfection of synthetic secondary effluent under laboratory controlled conditions, focusing on the post-irradiation bacterial regrowth. The influence of various internal and external ...
Numerical modelling of constructed wetlands for wastewater treatment
Constructed Wetlands (CWs) are a wastewater treatment technology that inherits the purification potential of natural wetlands and optimizes it to comply with regulations for treated discharges. CWs have become an equally ...
Anaerobic digestion of animal by-products : pre-treatments and co-digestion
The meat sector is one of the most important industrial sectors in Europe and it is associated with the generation of large quantities of animal by-products not intended for human consumption (ABPs). The increasing demand ...
Effect of design and operational factors on the removal of emerging organic contaminants in constructed wetlands for wastewater treatment
Water of quality constitutes a scarce and essential resource for life and public health, and its sustainable management is of crucial importance. Thus, wastewater treatment, reuse and reclamation represent a key practice ...
Valorization of brines in the chlor-alkali industry. Integration of precipitation and membrane processes
Reuse of brines in the chlor-alkali industry can be benefitial both in terms of new material source for the industry and environmental impact reduction of the brines disposal. In this thesis, reuse of Seawater Reverse ...
Desert dust characterization in Northern Africa, Middle East and Europe through regional dust modelling, and satellite-borne and ground-based observations
The impact of mineral dust upon climate, ecosystems and air quality represents a major scientific and societal issue. The aim goals of the present Ph.D. Thesis are to evaluate the behaviour and to improve the forecasting ...
Sistema de pronóstico de radiación solar a corto plazo a partir de un modelo meteorológico y técnicas de post-proceso para España
El incremento de la utilizaci on de la energ a solar como fuente de generaci on de energ a requiere de una adecuada estimaci on de la radiaci on solar global y directa incidente en la super cie terrestre. La estimaci on ...
Evaluación de la sostenibilidad ambiental de hormigones con áridos reciclados procedentes de residuos de construcción y demolición
The concrete is one of the most important construction materials. Its sustainability is determined by its durability, its low maintenance and its ability to be reused, recycled or recovered. Hence, the use of recycled ...
Developing tools to evaluate the environmental status of Andean basins with mining activities
The water quality status of an Andean river basin was characterised and the pressures from anthropogenic activities were evaluated to enhance the available knowledge of the environment within an ecosystem in Peru. This ...
Study of methods for the improvement of the anaerobic digestion of lipids and long chain fatty acids
Anaerobic digestion is a biochemical process that transforms diverse categories of biomass feedstock to renewable energy, in the form of methane, and contributes to resources conservation and greenhouse gases emission ...
Modelització matemàtica de la transferència de massa i energia en el procés de compostatge
El procés de compostatge és complex degut a que hi intervenen simultàniamentfenòmens de naturalesa molt diversa que interactuen entre ells. La modelitzaciómatemàtica és una eina que facilita l’anàlisi d’aquests sistemes ...
Variational multiscale stabilization of finite and spectral elements for dry and moist atmospheric problems
In this thesis the finite and spectral element methods (FEM and SEM, respectively) applied to problems in atmospheric simulations are explored through the common thread of Variational Multiscale Stabilization (VMS). This ...
Modeling biotechnological processes under uncertainty anaerobic digestion as case study
En la pràctica de l’enginyeria, quan un model explícit d’un procés està disponible, es poden realitzar experiments numèrics per tal de predir el comportament futur del sistema, explicar o descriure el seu estat ocult, ...
Statocyst sensory epithelia ultrastructural analysis of Cephalopods exposed to noise
Controlled Exposure Experiments revealed lesions in the statocysts of four cephalopod species of the Mediterranean Sea (Sepia officinalis, Loligo vulgaris, Illex coindetii and Octopus vulgaris), when exposed to relatively ...
Estudio de la viabilidad técnico-económica y ambiental de la gestión de fangos EDAR por adición de CaO para su valorización en la industria cementera
Urban wastewater treatment plants produce a variety of residuals during their operation, the typology of which are in function of the design of the treatment process. The problem aborded in the present thesis refers to the ...
Regional and urban evaluation of an air quality modelling system in the European and Spanish domains
El impacto de la contaminación del aire es un tema crítico para el medioambiente y el clima. Una mala calidad del aire es un tema de importancia para la salud pública, especialmente en ambientes urbanos. El material ...
Turbulent structure in environmental flows: effects of stratification and rotation
Several series of experiments in stratified and in rotating/stratified decaying flows after a grid is used to stir the two layer stable fluid brine and fresh water set up. We measure by comparing the gained potential ...
Assesing variations in urban air quality when introducing on-road traffic management strategies by means of high-resolution modelling: application to Barcelona and Madrid urban areas
La contaminación del aire urbano tiene efectos negativos en la salud humana, los ecosistemas y se asocia con el transporte de contaminantes a larga distancia. La región del sur del Mediterráneo y en concreto la Península ...
Aplicación de membrana de nanofiltración para eliminar disruptores endocrinos en la potabilización del agua
Muchas de las actividades humanas contribuyen al deterioro del medio ambiente debido a la gran variedad de residuos químicos vertidos. Algunas de estas sustancias químicas son bastante persistentes y causan serios efectos ...
Desarrollo de una metodología para la valoración en el análisis del ciclo de vida aplicada a la gestión integral de residuos municipales
El Análisis del Ciclo de Vida (ACV) es una herramienta metodológica que determina los potenciales impactos ambientales asociados con un producto o servicio, desde la extracción de la materia prima hasta su disposición final ...
