| Περίληψη: | Membrane bioreactor (MBR) has been widely accepted as an advanced wastewater treatment technology, while biofouling is still a bottleneck in extensive growth of MBR markets. The introduction of quorum quenching (QQ) bacteria, which disrupts the formation of the biofouling layer on the immersed membrane surface, holds the promise to inhibit biofouling problem for MBR. Nevertheless, high strength wastewater containing high chemical oxygen demand (COD) and ammonia nitrogen (N) could easily promote biomass growth in MBRs, leading to higher extracellular polymeric substance (EPS) production and resulting in higher membrane biofouling. This study achieved a double critical flux enhancement (0.3→0.6 m/day) coupled with a >14 days operational extension through QQ-mediated EPS modulation, specifically targeting protein reduction (50.68 % decrease). Notably, QQ efficacy persisted under high-strength conditions, maintaining >94 % NH₄⁺-N removal and >93 % COD removal across cycles. These findings substantiate the scalability of the QQ strategy for the treatment of high COD and high N wastewater at a high flux of 0.6 m/day, offering a robust theoretical framework for its implementation in mitigating membrane fouling and optimizing the performance of membrane reactors in practical applications.
