Influence of the initial sludge characteristics and acclimation on the longterm performance of double-compartment acetate-fed microbial fuel cells

In this work, three double-compartment MFCs (DC-MFC) were operated for 1 month in order to compare their performances in terms of wastewater treatment capacity and electricity production and to get information about how this performance is influenced by the start-up procedure. To do this, they under...
