Wastewater represents a very suitable source of energy, as it contains organic compounds that need to be removed and can be converted into valuable products (e.g. methane, chemicals). In this context, Microbial Fuel Cell (MFC) is a sustainable and efficient technology to recover electricity from organics in wastewater, thus making profit from a treatment process. Microorganisms oxidize the organics (e.g. acetate) in the wastewater and produce electrons, which are then transferred from the anode to the cathode producing thereby current. In this study, capacitive MFCs are studied as an alternative to classical MFCs. The main difference relies on the use of capacitive materials as electrodes which provide with a large (porous) surface area for the growth of biofilms as well as the storage of electrons in form of electrical double-layer (EDL). Granular activated carbon represents a suitable three-dimensional capacitive electrode material for MFCs that can be implemented under many reactor configurations (e.g. fixed or fluidized beds).

Toelichting (Engels) Wastewater represents a very suitable source for electricity production, as it contains compounds such as organics and nutrients (nitrogen, phosphate, potassium) that can be recovered or converted into valuable products (e.g. methane, chemicals). Wastewater needs to be treated before releasing it to the environment, as these compounds can cause problems like eutrophication (i.e. excess of algae growth). In this context, microbial fuel cell (MFC) is a carbon dioxide neutral, sustainable and efficient technology to recover electricity from organics in wastewater, thus making profit from a treatment process.

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
