Integrating Biological Treatment and Electro-Oxidation in an Anaerobic Biomass Membrane Bioreactor for Innovative and Integrating Urban Wastewater Treatment
Résumé
The global population's increasing demand for clean water has driven a shift towards reclaimed and reused water. Anaerobic Membrane BioReactor (AnMBR) stands out as a promising solution for wastewater treatment, offering advantages over traditional methods. However, as AnMBR gains recognition, the need to prioritize comprehensive removal of organic matter and micropollutants becomes critical, aligning with evolving environmental regulations like the European Water Framework Directive. This study focuses on an inventive AnMBR configuration, aiming to remove persistent organic micropollutants and harness energy from urban wastewater. The setup integrates biological treatment and electro-oxidation within a specialized AnMBR featuring granular sludge (e-GAnMBR), intensifying reactions and addressing AnMBR challenges. Specifically targeting diuron, carbamazepine, and perfluorooctanesulfonic acid, the study explores their degradation pathways and toxicity, marking a significant step in sustainable wastewater treatment.
