Cold-adapted membrane-aerated biofilm reactor for domestic wastewater treatment in northwest China: Pollutant removal performance and mechanistic insights

Membrane-aerated biofilm reactors (MABRs) have considerable potential for carbon and nitrogen removal from domestic wastewater. However, their long-term performance under high-altitude, low-temperature, and low-C/N conditions remains insufficiently understood. In this study, a pi...

Performance and Resilience of Oxidation Ditch and Step-Feeding Anoxic–Oxic Processes during Extreme Rainfall Events: Evaluation and Optimization Strategies for Wastewater Treatment Plants

Abstract Extreme rainfall poses significant challenges to the operational stability of wastewater treatment plants (WWTPs). This study used full-scale plant data to evaluate the robustness and nutrient removal performance of oxidation ditch (OD) and step-feeding anoxic–oxic (AO)...
