Anode hydrodynamics in Bioelectrochemical Systems

This study assesses the hydrodynamics in the anode compartment of a bioelectrochemical system (BES) when using different electrode materials (graphite rod, granular graphite, stainless steel mesh or graphite plate). For this purpose, computational fluid dynamics (CFDs) modelling was used. Granular graphite or stainless steel mesh allowed a better water flow distribution through the system favouring biomass attachment and consequently, removal efficiency and electricity production. This study provides the necessary mechanistic understanding on how these materials affect the hydrodynamic and its substrate distribution behaviour within the bioanodes and its electricity production.
