Claim Text:
1. A modular water treatment system comprising a plurality of microbial fuel cells (MFCs), wherein each of the plurality of MFCs comprises an anode connected to a cathode by a conductive material, and wherein: the anode is physically associated with a first microbial population; and the cathode is physically associated with a second microbial population, the electrons transported to the cathode electrode are used as a source of energy for a distinct microbial population physically associated with the cathode, wherein at least a portion of the second microbial population is growing on the cathode surface, the distance between the anode and cathode is less than 3 cm, there is no proton selective material between the anode and the cathode, and the surface area of the cathode is at least twice the surface area of the anode.
