Ammonia removal from water by liquid-liquid membrane contactor under closed loop regime
(2012)
Conference report
Restricted access - publisher's policyAmmonia separation from water by a membrane contactor was simulated on transient state and compared with experimental data. Aqueous low concentrated solution of ammonium with high pH has been pumped inside a hydrophobic ... -
Análisis de la dinámica del nitrógeno en un sistema continuo acoplado contactor de membrana hidrofóbica / reactor anaerobio
(Universitat Politècnica de Catalunya, 2016-07-15)
Bachelor thesis
Open AccessCurrently the management of organic waste has become a major problem due to the fact that a bad management can produce emissions of greenhouse gases into the atmosphere and leaching of this waste can seep into contaminating ... -
Avaluació experimental d'un procés de recuperació d'amoníac de purins
(Universitat Politècnica de Catalunya, 2019-01-17)
Bachelor thesis
Restricted access - author's decisionLa finalitat d’aquest treball de fi de grau és trobar quina és la manera més eficient d’extreurel’amoníac dels purins del porc. Aquest procés es farà mitjançant una maquinària que utilitza el buit per fer circular la fracció ... -
Biofiltration of WWTP sludge composting emission at contact times of 2 to 8 seconds
(2013)
Conference report
Open AccessThe performance of a biotrickling filter for the abatement of composting emissions was evaluated at short contact times of 2 to 8 seconds. The effect of EBRT, pH control and water renovation rate were evaluated. The ... -
Characterization of organic packing materials in the removal of ammonia gas in automated biofilters
(Consejo Superior de Investigaciones Científicas (CSIC), 2005)
Conference report
Open AccessA fully-automated pilot-scale biofilter filled with coconut fiber as packing material was investigatedfor treatment of ammonia-containing off-gas streams. Coconut fiber was completely characterized ... -
Contactores de membranas líquido-líquido para la valorización de amonio de aguas residuales urbanas
(Universitat Politècnica de Catalunya, 2020-02-28)
Bachelor thesis
Restricted access - confidentiality agreementUno de los principales problemas al que se enfrenta la sociedad es la reducción de los recursos naturales debido al aumento de la población. La recuperación de recursos de fuentes secundarias (e.g. residuos industriales y ... -
Dynamic modelling of ammonia biofiltration from waste gases
(Consejo Superior de Investigaciones Científicas (CSIC), 2005)
Conference report
Open AccessA dynamic model to describe ammonia removal in a gas-phase biofilter was developed. The math-ematical model is based on discretized mass balances and detailed nitrification kinetics that includeinhibitory ... -
Estudi de l'absorció d'altes càrregues d'amoníac en planta pilot
(Universitat Politècnica de Catalunya, 2019-01-25)
Bachelor thesis
Restricted access - author's decisionEn l’actualitat, un dels problemes més globalitzats i en el que s’hi està treballant més per a reduir el seu impacte a nivell mundial és el canvi climàtic. Una de les mesures implantades més importants i en continu ... -
Estudi de l'eficiència de membranes hidrofòbiques per a la separació d'amoníac de residus amb alt contingut en amoni a diferents temperatures
(Universitat Politècnica de Catalunya, 2015-10-29)
Bachelor thesis
Open AccessHigh ammonia (NH_3) concentrations in the process of anaerobic digestion are specially problematical due to the great inhibition that they cause in the function of methanogenic organisms. One of the most interesting options ... -
Estudio evaporacion de disoluciones acuosas de amoniaco
(Universitat Politècnica de Catalunya, 2012-06)
Master thesis
Restricted access - author's decisionEn este trabajo se ha estudiado la evaporación de amoníaco desde disoluciones acuosas para diferentes velocidades de aire. Los valores obtenidos se han comparado con los principales modelos de evaporación encontrados en ... -
Hydrogen and oxygen production using wastewater effluent treated with ultra-filtration and membrane distillation (Greenlysis)
(2012)
Article
Open AccessCONCLUSIONS: * When MD technology is implemented for wastewater treatment it is important to consider that the presence of ammonia can have an important impact in the final water quality in terms of conductivity. * On-going ... -
Integration of liquid-liquid membrane contactors and electrodialysis for ammonium recovery and concentration as a liquid fertilizer
(2020-04-13)
Article
Restricted access - publisher's policyThe accumulation of ammonia in water bodies can cause eutrophication and reduce water quality. Furthermore, 80% of the ammonia in the world is consumed as fertilizer, which makes it a resource that can be recovered under ... -
Modelización de la dinámica de los microorganismos anaerobios sintróficos oxidantes del ácido acético (SAO)
(Universitat Politècnica de Catalunya, 2014-07-25)
Bachelor thesis
Open AccessIn the anaerobic digestion process, the most sensitive step is the methanogenesis. The main methane producing organisms are the acetoclastic methanogenic archaea that degrade the acetic acid to methane. These microorganisms ... -
Performance characterization of a full-scale biofilter at an organic waste treatment plant
(2004)
Conference report
Open AccessData from the regular monitoring of a full-scale biofilter at a municipal solid waste treatment facility for the integral treatment of domestic residues was analyzed in order to assess potential operational problems and ... -
Study of NH3 removal by gas-phase biofiltration: effects of shock loads and watering rate on biofilter performance
(Universidade da Coruña, 2007)
Conference report
