Bioelectrochemical and Anaerobic Processes for Sustainable Wastewater Valorization: Mechanisms, Resource Recovery, and Circular Economy Integration
Conventional anaerobic digestion (AD), despite its proven efficiency in wastewater treatment, faces limitations due to energy requirements and extended hydraulic retention times, with methane yields from waste-activated sludge rarely exceeding 50% of the stoichiometric maximum at retention times of 20 days or more and...
