Small scale ceramic MFCs for efficient energy harvesting from wastewater and full system development (2016)
Presentation / Conference Contribution

The main aim of this work was to increase the efficiency of the ceramic based MFCs by compacting the design and exploring the ceramic support as the building block for small scale modular multi-unit systems. The improved energy density would then all... Read More about Small scale ceramic MFCs for efficient energy harvesting from wastewater and full system development.

Electricity and disinfectant production from wastewater: Microbial Fuel Cell as a self-powered electrolyser (2016)
Journal Article

This study presents a simple and sustainable Microbial Fuel Cell as a standalone, self-powered reactor for in situ wastewater electrolysis, recovering nitrogen from wastewater. A process is proposed whereby the MFC electrical performance drives the e...

Regeneration of the power performance of cathodes affected by biofouling (2016)
Journal Article

© 2016 The Authors. Air cathode microbial fuel cells (MFCs) were used in a cascade-system, to treat neat human urine as the fuel. Their long-term operation caused biodeterioration and biofouling of the cathodes. The cathodes were made from two graphi...

Microbial Fuel Cell-driven caustic potash production from wastewater for carbon sequestration (2016)
Journal Article

© 2016 The Authors. This work reports on the novel formation of caustic potash (KOH) directly on the MFC cathode locking carbon dioxide into potassium bicarbonate salt (kalicinite) while producing, instead of consuming electrical power. Using potassi... Read More about Microbial Fuel Cell-driven caustic potash production from wastewater for carbon sequestration.
