Taking advantage of autotrophic nitrogen removal: potassium and phosphorus recovery from municipal wastewater

Johansson, Sara (Date of defense: 2019-04-29)

Increasing awareness on the limited nature of the raw materials for the production of inorganic fertilizer is pushing for a shift from removal to recovery of nutrients from waste streams. In municipal ...

Insights into key parameters for bio-alcohol production in syngas fermentation using model carboxydotrophic bacteria

Ramió Pujol, Sara (Date of defense: 2016-07-07)

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 ...

Siloxane removal in the energy recovery of biogas: sequential adsorption/oxidation processes

Cabrera-Codony, Alba (Date of defense: 2016-07-27)

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 ...

Response of the benthic macroinvertebrate community to a point source in La Tordera stream (Catalonia, NE Spain)

Ortiz Durà, Jesús (Date of defense: 2005-06-30)

Vam monitoritzar paràmetres físics i químics, macroinvertebrats bentònics, clorofil·la a, productors primaris i matèria orgànica durant un any (2001-2002) per examinar els efectes d'una font puntual ...

Developing a desertification indicator system for a small Mediterranean catchment: a case study from the Serra de Rodes, Alt Empordà, Catalunya, NE Spain

Dunjó Denti, Gemma (Date of defense: 2004-03-15)

La desertificació és un problema de degradació de sòls de gran importància en regions àrides, semi-àrides i sub-humides, amb serioses conseqüències ambientals, socials i econòmiques com a resultat de ...

Integrating computational fluid dynamics and biological model to assess wastewater reactor design

Vilà-Rovira, Albert (Date of defense: 2017-10-20)

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 ...

Roadmap for scaling up thermophilic CO2 bioreduction to acetate : shedding light on using surplus renewable energy and industrial off gases

Rovira Alsina, Laura (Date of defense: 2022-12-02)

Carbon dioxide (CO2) is largely emitted in the ignition of fossil fuels for transport, electricity generation or other industrial processes. CO2 is an inorganic compound that exists naturally on Earth, ...
