Scalable continuous flow microbial fuel cells

A system for energy generation and wastewater treatment, comprising:

• a plurality of modular microbial fuel cell (MFC) devices to bioelectrochemically process wastewater by concurrently generating electrical energy and digesting organic contaminants and particulates in the wastewater to yield a treated water, wherein each modular MFC device of the plurality of modular MFC devices comprises a housing and a bioelectrochemical reactor that is encased within the housing, wherein the bioelectrochemical reactor includes a plurality of anodes arranged between a cathode assembly including at least two cathodes separated on opposing sides of the plurality of anodes and adjacent to a first set of opposing sides of the housing, wherein an anode of the plurality of anodes includes carbon fibers that protrude from an interior cylinder,
• wherein at least two of the modular MFC devices of the plurality of modular MFC devices are configured in a series arranged in a single horizontal plane along a vertical direction.
