1D-Space dynamic mathematical model of the composting process
(2016)
Conference lecture
Open AccessMathematical modelling is a helpful tool to analyse complex systems, but its development and application to the composting process has been rather scarce up to date. The use of mathematical models is common in complex ... -
A comprehensive and manageable mathematical model for the composting process
(2006)
Conference lecture
Restricted access - publisher's policyMathematical modelling for composting problem -
A new structured mathematical model of the composting process

Characterization of methanogenic biomass from a full-scale digester that might harbour SAO activity
(2015)
Conference lecture
Open AccessBiomass from a full-scale anaerobic digester treating nitrogen-rich wastes was characterized by methanogenic batch activity assays at different ammonia concentrations. SAO was demonstrated by isotopic 13C fractionation of ... -
Efficient dynamic simulation of pH in processes associated to biofiltration of volatile inorganic pollutants
(2010)
Conference lecture
Open AccessThis work proposes a generic methodology to include the pH as a state variable in mathematical models of bioreactors. An ordinary differential equation for pH is stated and introduced into the general model structure of a ... -
Electroactive biofilm adapted to a high nitrogen loads and electricity generation in a microbial fuel cell fed with pig slurries
(2012)
Conference lecture
Restricted access - author's decisionIn the present study, the anodic biofilm of two MFC reactors (MFC-1 and MFC-2) working at high ammonium loading rates were characterized in electrochemical and microbial terms. -
Empirical characterisation and mathematical modelling of settlement in composting batch reactors
(2012-01)
Article
Restricted access - publisher's policyThe settlement of organic matter during composting was measured at different levels during the active biodegradation phase in forced-aerated static reactors loaded with different mixtures of organic wastes. The temperature ... -
Estudios sobre gestión y tratamiento de deyecciones ganaderas en el LEA: un ejemplo de investigación orientada
(Universitat de Lleida, 2021-05-05)
Part of book or chapter of book
Open AccessEn el presente capítulo se hace una revisión de trabajos de investigación y desarrollo sobre gestión y tratamiento de deyecciones ganaderas por parte de un grupo de investigación desde mediados de los años 90. Con un enfoque ... -
Exergetic optimisation of a solar energy installation
(Société Marocaine des Sciences Mécaniques, 2009)
Conference report
Open AccessThis paper deals with the Exergetic optimisation stutdy of the PCM’s slabs- Solar Energy Storage Tank (SEST). Both melting temperature and the maximum power output taking into account the phase change process are determined. -
Long-chain fatty acids inhibition and adaptation process in anaerobic thermophilic digestion: Batch tests, microbial community structure and mathematical modeling
(2010-04-01)
Article
Restricted access - publisher's policyBiomass samples taken during the continuous operation of thermophilic anaerobic digestors fed with manure and exposed to successive inhibitory pulses of long-chain fatty acids (LCFA) were characterized in terms of specific ... -
Microbial community dynamics in two-chambered microbial fuel cells : effect of different ion exchange membranes
(2015-08-01)
Article
Open AccessBACKGROUND: The utilization of different kinds of ion exchange membrane is a common practice in bioelectrochemical systems such as two-chambered microbial fuel cells (MFCs). However, little is known about the effect of ... -
Modelación dinámica del pH en sistemas biológicos: aplicación a la digestión anaerobia
(2010)
Conference lecture
Restricted access - author's decisionEn el presente trabajo se estudian distintas metodologías para modelar el pH en sistemas biológicos. En particular se analiza el caso de la digestión anaerobia. Se compararon 5 metodologías, 2 basadas en sistemas de ... -
Modelització matemàtica de la transferència de massa i energia en el procés de compostatge
(Universitat Politècnica de Catalunya, 2012-11-23)
Doctoral thesis
Open AccessEl procés de compostatge és complex degut a que hi intervenen simultàniamentfenòmens de naturalesa molt diversa que interactuen entre ells. La modelitzaciómatemàtica és una eina que facilita l’anàlisi d’aquests sistemes ... -
Modelización matemática de procesos biológicos de tratamiento de residuos: estudio de casos
(2006)
Conference lecture
Restricted access - author's decisionLos modelos matemáticos se han convertido en una herramienta básica para aumentar la comprensión de los sistemas de tratamiento. En este sentido, la modelación permite crear un lenguaje de comunicación común, orientar el ...
