A novel simulation model, BK_BiogaSim for design of onsite anaerobic digesters using two-stage biochemical kinetics: Codigestion of blackwater and organic waste
Neba, Fabrice Abunde; Asiedu, Nana Yaw; Morken, John; Ahmad, Addo; Seidu, Razak (Journal article; Peer reviewed, 2020)The design of biogas reactors for blackwater treatment provides special challenges due to significant variability in blackwater characteristics, the complexity of biological systems, and the need, in many cases, to operate ... -
Attainable regions and fuzzy multi-criteria decisions: Modeling a novel configuration of methane bioreactor using experimental limits of operation
Neba, Fabrice Abunde; Asiedu, Nana Yaw; Addo, Ahmad; Seidu, Razak (Journal article; Peer reviewed, 2020)This study sets out to develop an approach that couples attainable regions and fuzzy multicriteria decision methods for modeling optimal configurations of multistage digesters without using a kinetic model of the process. ... -
Modeling, optimization and kinetic analysis of the hydrolysis process of waste cocoa pod husk to reducing sugars
Mensah, Mary; Asiedu, Nana Yaw; Neba, Fabrice Abunde; Amaniampong, Prince Nana; Boakye, Patrick; Addo, Ahmad (Peer reviewed; Journal article, 2020)Lignocellulosic biomass represents an important chemical resource. In the quest for the heightened interest for waste management and the successful utilization of solid waste materials into useful products, cocoa pod husk, ... -
Simulation of two-dimensional attainable regions and its application to model digester structures for maximum stability of anaerobic treatment process
Neba, Fabrice Abunde; Asiedu, Nana Yaw; Addo, Ahmad; Morken, John; Østerhus, Stein Wold; Seidu, Razak (Journal article; Peer reviewed, 2019)Unlike high-rate anaerobic digesters that employ some mechanism to retain microbial sludge mass, low-rate systems use sufficiently long hydraulic retention times to ensure process stability, which becomes economically ... -
Use of attainable regions for synthesis and optimization of multistage anaerobic digesters
Neba, Fabrice Abunde; Asiedu, Nana Yaw; Addo, Ahmad; Morken, John; Østerhus, Stein Wold; Seidu, Razak (Journal article; Peer reviewed, 2019)Anaerobic digestion involves multiple reactions, and when operated as a single stage, the process conditions are only suitable for all the reactions with no particular reaction being optimized, hence limiting overall ...
