Ammonium as a Carbon-Free Electron and Proton Source in Microbial Electrosynthesis Processes
Sivalingam, Vasan; Dinamarca, Carlos; Arachchige, Gamunu L. Samarakoon; Winkler, Dietmar; Bakke, Rune (Peer reviewed; Journal article, 2020)Biogas upgrading to biomethane with microbial electrosynthesis (MES) is receiving much attention due to increasing biomethane demands and surplus renewable energy. Research has demonstrated the feasibility of MES to increase ... -
Modelling temperature transition and co-digestion in VEAS biogas process
Mikelsone, Veronika (Master thesis, 2021)Anaerobic digestion (AD) is a well-established way to stabilise concentrated sludge produced in wastewater treatment (WWT) plants. The benefit of the process is the production of biomethane and digestate that can be used ... -
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 ... -
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 ...
