Neba, Fabrice Abunde; Tornyeviadzi, Hoese Michel; Asiedu, Nana Y.; Addo, Ahmad; Morken, John; Østerhus, Stein Wold; Seidu, Razak (Peer reviewed; Journal article, 2020) -
A coupled modeling of design and investment parameters for optimal operation of methane bioreactors: Attainable region concept approach
Neba Abunde, Fabrice; Nana, Aseidu; Addo, Ahmad; Morken, John; Østerhus, Stein Wold; Seidu, Razak (Peer reviewed; Journal article, 2020)Current practice to design methane bioreactors does not consider all degrees of freedom simultaneously, which raises question of global optimality. This study presents a model-based design framework, which simultaneously ... -
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 (Peer reviewed; Journal article, 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 ...
