I want to know the definition of operated in fed-batch mode/operated in batch mode/operated under continuous flow Microbial Fuel Cell (MFC) / Microbial Electrolysis Cell(MEC).
These definition refer to chemical engineering notations.
Fed-batch mode means there is a physical inlet flow with no outlet, or vice versa,
Batch mode means there are neither inlet nor outlet flows (like with a vapor cooker),
Continuous flow means there are both inlets and outlets with, generally speaking but not limited too, the total inlet mass flows = total outlet mass flows, so that there is no mass accumulation.
Dear Dr.Gregory Francois,
How we can determine the fed -batch cycle time in Microbial electrolysis cells(MECs)?
and when we can start the feeding the MECs?
Batch flow is the complete replacement of media once the bacteria have consumed the substrate.
Fed-batch flow is medium replaced at the end of each fed-batch cycle or a voltage of approximately 20 mV. About 20-30 percent ofthe previous solution is retained.
Continuous flow is mainly characterized by the hydraulic retention time (HRT).
