Is Electro-Stimulation Always Effective for Methanogenesis? A Holistic Assessment of Electric Potential and Current Effects in Highly Conductive Systems
Electro-stimulated anaerobic digestion (EAD) typically relies on voltage-only regulation, neglecting the impacts of the associated response current, particularly in highly conductive systems. Herein, we investigated an EAD system for treating iron-containing sludge digestate. Unexpectedly, under appropriate applied v...
