A dynamic knowledge-based decision support system to handle solids separation problems in activated sludge systems: development and validation
El sistema de fangs activats és el tractament biològic més àmpliament utilitzat arreu del món per la depuració d'aigües residuals. El seu funcionament depèn de la correcta operació tant del reactor biològic com del decantador ...
A methodology for the automation of building intelligent process control systems
(English) One of the major problems to design and implement control and supervision systems for real-world processes lies in the need to stablish an ad-hoc solution for each process, i.e., environmental systems in this ...
A new experimental model to study bone and cartilage formation using a bioengineering approach
La medicina regenerativa és una disciplina que ha guanyat reconeixement en les últimes dècades pel fet que moltes malalties no són tractables amb fàrmacs convencionals. Molts grups de recerca i empreses inverteixen temps ...
Abatement of siloxanes in sewage biogas: coupling adsorption and biological treatments
The anaerobic digestion of organic matter causes the formation of biogas that can be used in energy conversion systems for the production of electricity and heat, injection into the gas grid or as a fuel. However, biogas ...
Adsorbentes preparados a partir de residuos y su aplicación en la eliminación de compuestos causantes de olores (NH3 y H2S)
This thesis is focused on two environmental issues. The first one is the recovery of different wastes, such as sewage sludge and fly ashes, and the second one is related to the removal of odour causing compounds which are ...
Adsorbents a partir de fangs biològics excedents de depuradora mitjançant l'aplicació de microones: estudi d'obtenció, caracterització i aplicació en fase líquida
El fang biològic es produeix en les plantes de tractament d'aigües residuals urbanes i industrials. El tractament i la gestió dels fangs és un dels problemes més importants en el camp del tractament de les aigües residuals. ...
Adsorption of organic and emerging pollutants on carbon materials in aqueous media : environmental implications
In the last two decades an increasing presence of organic substances such drugs, pesticides, etc. has been detected in water which may affect the health of the organisms and the environment. Some of these contaminants ...
Advanced technologies applied to wastewater treatment plant effluents
This thesis is formed as a summary of publications developed in the Chemical Engineering Department from the University of Barcelona. The six publications of this thesis are focused on the application of advanced technologies ...
Algorismes per a la reconstrucció de ràfegues de dades perdudes del nivell d'aigua del dipòsit principal de la ciutat de Vic
Els sistemes SCADA (Supervisory Control And Data Acquisition) poden acumular gran quantitats de dades de diferents tipus de sensors que s'emmagatzema en bases de dades per tenir registres històrics. Per utilitzar aquestes ...
Anaerobic digestion and bioeletrochemical systems combination for energy and nitrogen recovery optimisation
Anaerobic digestion (AD) is a widespread technology for treating high strength waste streams, such as livestock manure. AD has some limitations: i) high nutrient concentrations in effluents (especially nitrogen and ...
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 ...
Analysis, occurrence, fate and behaviour of emerging micropollutants in wastewater and the receiving environment
The presence of xenobiotics - such as pharmaceutically active compounds, endocrine disrupting compounds and pesticides - in the aquatic environment has risen great environmental concern due to their high toxicity even at ...
Analytical methodology based on a silicone rod (SR) micro extraction combined with HPLC-DAD method for the determination of pharmaceuticals and antibacterial products in effluent wastewaters: characterization of the sorption removal processes by cork
Solid-phase microextraction (SPME) allow the achievement of high enrichment levels by using small volumes of solvents, enabling the low detection limits required for the determination of ketoprofen, naproxen, carbamazepine, ...
