    Biomass from two full-scale anaerobic digester treating different wastes regarding to nitrogen concentrations and operating under different hydraulic retention time was characterized by methanogenic batch activity assays ...
  • Assessment of a composting process for the treatment of beef cattle manure 

    Magrí Aloy, Albert; Teira Esmatges, Rosa Maria (2015)
    Article
    Accés obert
    The intensive breeding of beef cattle in Juncosa de les Garrigues (Catalonia, Spain) leads to the production of a large volume of manure that needs appropriate management. Land application in the area at agronomic rates ...
  • Batch enrichment of anammox bacteria and study of the underlying microbial community dynamics 

    Connan, Romain; Dabert, Patrick; Khalil, Hassan; Bridoux, Gilbert; Béline, Fabrice; Magrí Aloy, Albert (2016)
    Article
    Accés restringit per política de l'editorial
    The anaerobic ammonium oxidation (anammox) consists on the biological conversion of ammonium (NH4+) into dinitrogen gas under absence of oxygen. Nitrite (NO2-) is a substrate of the anammox reaction, but also an inhibitor ...
  • Nitrification of leachates from manure composting under field conditions and their use in horticulture 

    Cáceres Reyes, Rafaela; Magrí Aloy, Albert; Marfà Pages, Oriol (2015)
    Article
    Accés restringit per política de l'editorial
    This work aimed to demonstrate the feasibility of nitrification applied to the treatment of leachates formed during composting of cattle and pig manure in order to promote their further use as liquid fertilizer in horticulture. ...
  • Effects of hydrothermal aging on the water uptake and tensile properties of PHB/flax fabric biocomposites 

    Ventura Casellas, Heura; Claramunt Blanes, Josep; Rodríguez Pérez, Miguel Ángel; Ardanuy Raso, Mònica (2017-06-12)
    Article
    Accés obert
    This research analyses the effect of hydrothermal aging on the water uptake and mechanical performance of biocomposites based on a polyhydroxyalkanoate matrix and flax fibre reinforcement in the form of nonwoven (NW) ...
  • Quality and bioaccessibility of total phenols and antioxidant activity of calçots (Allium cepa L.) stored under controlled atmosphere conditions 

    Zudaire, Lorena; Viñas, Inmaculada; Abadias, Maribel; Simó Cruanyes, Joan; Echeverria, Gemma; Plaza, Lucia; Aguiló-Aguayo, Ingrid (2017-07-01)
    Article

    Calçots are the floral stems of the second-year onion (Allium cepa L.) resprouts with economic importance in Spain, where they are usually consumed roasted. The effect of two controlled atmospheres (CA) of 2.0% O2 + 3.5% ...
  • Influence of fish swimming on the flow pattern of circular tanks 

    Masaló Llorà, Ingrid; Oca Baradad, Joan (2016-09-01)
    Article
    Accés restringit per política de l'editorial
    The effect of swimming fish on the average velocity and velocity profile of a circular tank was studied. Working with different inlet diameters and flow rates, nine different impulse forces (configurations) were evaluated. ...
  • Influence of support materials on methanogenic biofilm formation in ammonia rich environments 

    Ruiz Sánchez, Josep; Fernández García, Belén; Viñas Canals, Marc; Guivernau Ribalta, Miriam; Tey, Laura; Riau Arenas, Victor; Flotats Ripoll, Xavier; Prenafeta Boldú, Francesc Xavier (Internatinal Water Association (IWA), 2016)
