BioElectrochemical Systems are an emerging technology of interest. Central to the successful operation of these systems is the development of a biofilm on an electrode surface that facilitates the interaction of microorganisms capable of extra-cellular electron transfer. Porous graphite is typically chosen as the electrode material. However, other materials could contribute to a significant improvement in reactor performance. In order to evaluate these novel materials, a platform methodology is required. In this study, E-QCM-D was evaluated using a gold electrode, a mixed biofilm population and a challenging real influent (fermented solubilised sludge). The results gave real-time feedback on both the acoustic and electrochemical impedance of the working electrode, hence providing information about biofilm thickness, viscoelasticity, kinetics and mass transport. The use of E-QCM-D is novel for this field and has the potential to provide a wealth of new data to help optimise the performance of biofilms in these systems.
