Modeling N/S ratio and temperature effects in simultaneous biological denitrification and sulfide oxidation
Sposob, Michal; Bakke, Rune; Dinamarca, Carlos (Journal article; Peer reviewed, 2017)A model describing the simultaneous removal of NO3- and HS- by microorganisms is presented here. The oxidation of HS- (electron donor) can be controlled by the appropriate dosage of NO3-. The developed model, which includes ... -
Modelling and Simulation of an Electrochemically Mediated Biofilm Reactor Biogas Upgrading
Neupane, Saroj (Master thesis, 2022)Marzieh Domirani et al. (2021) had developed the mechanistic model with the implementation of integration of microbial electrosynthesis (MES) with anaerobic digestion (AD) technology for biogas upgrading. The model's ... -
Moving Bed Biofilm Process in Activated Sludge Model 1 for Reject Water Treatment
Sivalingam, Vasan; Arachchige, Gamunu L. Samarakoon; Dinamarca, Carlos (Peer reviewed; Journal article, 2021)A moving bed biofilm (MBB) process was modelled in AQUASIM using the standard activated sludge model 1 (ASM1) as a baseline. The model was controlled against experimental data from a pilot Hybrid Vertical Anaerobic Biofilm ... -
Process parameters affecting the sustainability of fermentative hydrogen production: A short review
Dinamarca, Carlos; Bakke, Rune (Journal article; Peer reviewed, 2011)Anaerobic fermentation is regarded as the least energy intensive method for H2 production. Extensive literature on experimental attempts to achieve the highest possible theoretical yield (e.g. 4 mol H2/mol glucose) is ... -
Simple modelling approach using Modelica for microbial electrosynthesis
Arachchige, Gamunu L. Samarakoon; Winkler, Dietmar; Sivalingam, Vasan; Dinamarca, Carlos; Bakke, Rune (Peer reviewed; Journal article, 2020)This study intends to develop a simple mathematical model that contributes to the integration of Microbial Electrosynthesis (MES) in AD to reduce CO2 to CH4. Open-source modelling language Modelica was used to build the ... -
Simulation of the Effect of Local Electric Potential and Substrate Concentration on CO2 Reduction via Microbial Electrosynthesis
Ahmadi, Vafa; Dinamarca, Carlos (Peer reviewed; Journal article, 2022)Integrating anaerobic digestion into electrochemical reactors is an advanced technology for biomethane recovery. Imposing low electric potential between electrodes, supplies CO2, electrons, and hydronium ions from anodic ... -
Simultaneous hydrogen production and consumption in Anaerobic mixed culture fermentation
Dinamarca, Carlos (Journal article, 2012)The aim of the present study is to investigate the relevance of homoacetogenic H2 consumption on the bio-hydrogen yield and products distribution in mixed culture fermentation. A hybrid anaerobic reactor was operated for ... -
Study on the Start-up of Anammox Process in Lab-scale Moving Bed Biofilm Reactor (MBBR)
Pathak, Sabin (Master thesis, 2021)The discharge of wastewater containing nitrogen compounds is harmful to marine life and human health, hence, many biological nitrogen removal methods are in use in many treatment plants in recent years. Among the several ... -
Syngas Fermentation Catalyzed by Electroactive Biofilm
Parhizkarabyaneh, Pouria (Master thesis, 2021)This report describes an experiment conducted to see whether syngas fermentation could be integrated into the single-cell microbial electrosynthesis process. In some gasfermentation strategies, the primary bottleneck is ... -
Temperature Effects in Anaerobic Digestion Modeling
Bergland, Wenche Hennie; Dinamarca, Carlos; Bakke, Rune (Conference object; Peer reviewed, 2015-11-25)Temperature effects on kinetic coefficients for the biochemical processes particle disintegration, hydrolysis and substrate uptake reactions were included in the anaerobic digestion model 1 (ADM1). It was evaluated on data ... -
This report forms part of the basis for assessing the student’s performance in the course
Saif, Mahedi Hasan Ibna (Master thesis, 2020)The reject water of any wastewater treatment plant (WWTP) contains carbon dioxide (CO2) and micro-organisms. The environmental biotechnology research group of the University of South-Eastern Norway (USN) is trying to ...
