The concept of critical flux, introduced by R.W. Field, defines the flux below which filtration resistance remains constant over time. Notably, this concept, originally for cross-flow filtration, faces challenges in dead-end (the dominant mode used drinking water ultrafiltration (UF)). Herein, leveraged regulated membrane biofilms, we proposed a novel biofilm-induced specific to filtration. Below biofilm could act like maintain mass balances biodegradation foulants, thereby preventing continuous increase resistance. Additionally, demonstrated an optimized strategy improve flux─backwashing without air scouring, doubled from 6 12 L·m–2·h–1. A life cycle analysis revealed that operating at can reduce energy consumption and minimize cleaning, effectively lowering overall costs (52%) carbon emissions (61%) compared conventional UF. Sensitivity also indicated extending reducing were crucial costs, while minimizing fossil usage was decisive emissions.
