    Development of a decision support system for the integrated control of membrane bioreactors 

    Monclús Sales, Hèctor (Date of defense: 2011-11-08)

    The work presented in this PhD thesis includes various partial studies aimed at developing a decision support system for membrane bioreactor integrated control. The decision support systems (DSS) have as a main goal to ...

    Effects of operational conditions on the performance of a partial nitritation SBR treating high nitrogen loads 

    Gabarró i Bartual, Jordi (Date of defense: 2014-07-18)

    The biological treatment of industrial wastewater containing high nitrogen concentrations (>1000 mg N L-1) and low biodegradable organic matter (bCOD) such as landfill leachate is nowadays challenging. Conventional ...

    Integrated operation of membrane bioreactors: simulation and experimental studies 

    Dalmau Figueras, Montserrat (Date of defense: 2014-10-17)

    Membrane bioreactors (MBR) are a combination of common bioreactors and membrane filtration units for biomass retention, presenting unique advantages like high effluent quality and a smaller footprint than the one by ...

    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, but its concentration ...

    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 in the siloxane ...
