From the laboratory to the wastewater treatment plant
Bacterial batteries: clean energy with dirty water

A large number of research laboratories are working on improving the performance of bacterial stacks by conducting studies on various aspects. Research is focusing on optimizing bacterial cell performance in terms of energy production and simultaneous treatment of organic pollution. The electrical performance of the bacterial cell is assessed on the basis of the maximum power density (W.m ^–2 or W.m ^–3 ) it delivers, which depends on the voltage (V) and current density (A.m ^–2 or A.m ^–3 ) generated by the oxidation-reduction reactions between the two electrodes,...
