Coupling Physical Cleaning with Quorum Quenching Membrane Bioreactor
Membrane biofouling is the major concern to be addressed in membrane bioreactors (MBRs). Synergistic combinations of quorum quenching and physical cleaning methods were applied to minimize membrane fouling in MBRs. Different types of physical cleaning modes, such as relaxation, air backpulsing, and permeate backwashing were used in combination with quorum quenching. A significant improvement in fouling control was accomplished when QQ was coupled with physical cleaning methods, especially in relaxation. In addition, mixed liquor properties and treatment performances were not affected by the QQ activity. This research was supported by a grant (2012001440001) from the Korea Environmental Industry and Technology Institute funded by the Ministry of Environment.
