    Optimisation of biological nitrogen removal processes to treat reject water from anaerobic digestion of sewage sludge 

    Galí Serra, Alexandre (Date of defense: 2006-10-03)

    In the present work, the biological treatment of real reject water (800 mg NH4+-N L-1) from anaerobic digestion of sewage sludge from a waste water treatment plant (WWTP) is carried out. <br/>The process was optimised with ...

    Wet oxidation processes for water pollution remediation 

    García Molina, Verónica (Date of defense: 2006-06-16)

    The main objective of this work was to test the efficiency of wet oxidation processes when treating several types of aqueous wastes. On one side its performance for the abatement of chloro-organic aromatic toxic pollutants, ...

    Nuevos tratamientos de lana con enzimas 

    Vílchez Maldonado, Susana (Date of defense: 2005-12-12)

    Uno de los objetivos destacables de los tratamientos textiles modernos es obtener el efecto requerido modificando preferentemente la superficie de las fibras a fin de mantener la calidad del material, utilizando procesos ...

    Reactivity of acid gas pollutants with Ca(OH)2 at low temperature in the presence of water vapour 

    Bausach Mercader, Marta (Date of defense: 2005-07-01)

    The reactivity of Ca-based sorbents with acid gases (specifically SO2, HCl and NO2) at low temperature has been a subject of interest in the last decades, since it constitutes the fundamental reactive system in a number ...

    Fenton and UV-vis based advanced oxidation processes in wastewater treatment: Degradation, mineralization and biodegradability enhancement 

    Rodríguez, Miguel (Date of defense: 2003-05-30)

    Up until relatively recently, the discharging of waste in the environment was the way of eliminating them, until the auto-purifying capacity of the environment was not sufficient. The permitted levels have been vastly ...

    Combination of photo-oxidation processes with biological treatment 

    Al-Momani, Fares (Date of defense: 2003-06-13)

    Comprising over 70% of the Earth's surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprised of hydrogen and oxygen, life on Earth would ...

    Degradation and biodegradability enhancement of nitrobenzene and 2,4-dichlorophenol by means of Advanced Oxidation Processes based on ozone. 

    Contreras Iglesias, Sandra (Date of defense: 2003-01-24)

    La presente tesis se inscribe en el marco de la combinación de los procesos de oxidación avanzada y biológicos para el tratamiento de un agua residual, en este caso, aguas residuales sintéticas conteniendo nitrobenceno ...
