Impact of seasonality on quorum quenching efficacy and stability for biofouling control in membrane bioreactors

Abstract

Low temperatures produce more biopolymers, leading to severe biofouling. Moving QQ sheets mitigate biofouling under cold weather conditions. QQ activities drop sharply with decreasing water temperatures. QQ sheets remain active during long-term field tests using real wastewater. QQ sheets have no impact on activated sludge treatment performance.
