Combining forward osmosis and anaerobic membrane bioreactor technologies for raw municipal wastewater treatment
In this thesis, different studies were performed to investigate the combination of FO for the pre-concentration of municipal WW with an anaerobic membrane bioreactor (AnMBR) for the production of biogas. Firstly, a ...
Underdrain design and operational conditions in sand media filters using reclaimed effluents in drip irrigation systems
At present, agriculture is the human activity which requires more volume of water. Given the importance and scarcity of this resource, the efficient use of water has become a priority. On one hand, if possible, it is ...
Influence of feeding restriction and dietary phosphorus levels on body tissue composition evaluated in vivo by computed tomography, bone mineralisation and sensory properties of the meat from gilts
Feeding strategy is very important for farmers to improve pig productive parameters and keep its competitive advantage in the market. The computed tomography (CT) technology can evaluate the effect of feeding strategy on ...
Evaluation and comparison of advanced treatment technologies to enhance the removal of pharmaceutical active compounds from wwtp secondary effluent
The presence of several pharmaceutical active compounds (PhACs) in water bodies has garnered increasing attention and worldwide concern. The effluents from wastewater treatment plants (WWTPs) are one of the main sources ...
Assessment and optimisation of the operation of integrated membrane system for wastewater reclamation
The combination of two membrane technologies coupled together in series has become a standard technology when it comes to producing reclaimed water of high quality for potable reclamation or industrial applications. This ...
Resilience of water resource recovery facilities: a framework for quantitative model-based assessment
The water sector is entering a period of uncertainty, as stressors such as climate change pose unknown risks to its infrastructure. Utilities need to build resilience to handle unpredictable changes, but the field of ...
Taking advantage of autotrophic nitrogen removal: potassium and phosphorus recovery from municipal wastewater
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 wastewater treatment ...
Aplicación de la transglutaminasa microbiana en quesos frescos de coagulación ácida y de coagulación enzimática
The aim of this doctoral thesis was to evaluate the application of microbial transglutaminase (MTGase), produced by BDF Natural Ingredients, in the manufacture of acid and enzymatic coagulation fresh cheeses. In the case ...
Environmental and socio-economical assessment of measures for the reduction of pharmaceuticals in rivers
Pharmaceuticals are ubiquitous water contaminants that have shown detrimental effects on aquatic organisms at low concentrations. National authorities are starting to plan and implement measures (Wastewater treatment plants ...
Biological control of quarantine bacterial plant diseases with Lactobacillus plantarum strains. Improvement of fitness and monitoring
The fruit production is threatened by several bacterial diseases, such as fire blight of apple and pear, bacterial canker of kiwifruit, bacterial spot of stone fruits, and angular leaf spot of strawberry. The conventional ...
Optimización del diseño de los filtros de arena utilizados en sistemas de riego por goteo
To achieve a sand filter design that reduce its pressure loss, computational fluid dynamics (CFD) tecnique was used combined with laboratory tests in a scaled filter using different filter media. The CFD models allowed to ...
Pharmaceutical and personal care products removal by advanced treatment technologies
This thesis evaluates different technologies for treating wastewater with high concentrations of PPCPs. Firstly, a state-of-art revision of advanced treatment technology for removing Triclosan (TCS) from waste water was ...
Materiales compuestos de una poliamida de origen renovable y fibras naturales de alto rendimiento: una sólida alternativa a los materiales compuestos de polipropileno reforzados con fibra de vidrio
The main goal of this thesis is the production and characterization of composites materials from a bio-based polyamide and natural fibres which could be more sustainable alternative to glass fibre reinforced polypropylene. ...
Assessment of struvite and K-struvite recovery from digested manure
Human population has had an impact on the natural phosphorus’ cycle, a limited resource, and the predictions show that this resource could be exhausted in 100-250 years. Therefore, the actions for the coming 10-25 years ...
Integrated management of bacterial spot disease of stone fruits caused by Xanthomonas arboricola pv. pruni: development of a disease forecasting system
Bacterial spot disease of stone fruits, caused by Xanthomonas arboricola pv. pruni, is of high economic importance in the major stone-fruit-producing areas worldwide. Disease control is mainly based on preventive measures, ...
Decision-support for adaptive and sustainable urban wastewater system management in the face of uncertainty
With sustainable development as the new overarching goal, urban wastewater system (UWS) managers are now being asked to take all social, economic, technical and environmental facets related to their decisions into account. ...
Greenhouse gas emissions from wastewater treatment processes: identifying triggering factors at laboratory and full-scale systems
This thesis focuses on the study of the global green house gas (GHG) emissions from wastewater systems. Nitrous oxide (N2O) and methane (CH4) are the main GHG directly emitted from wastewater treatment plants (WWTP). In ...
Development of new products from aquaculture fish species
Europeans are regular consumers of fish and aquaculture products. Therefore, five species of potential aquaculture rearing named: Meagre, Pikeperch, Grey Mullet, Greater Amberjack and Wreckfish were selected for new product ...
Integrating computational fluid dynamics and biological model to assess wastewater reactor design
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 technologies for wastewater ...
