- Abstract:
- Membrane bioreactor (MBR) has been widely used in water treatment due to its advantages such as small floor area and low sludge yield. However, frequent membrane cleaning and membrane replacement caused by membrane fouling increase the actual operating cost of MBR, which are the main factors restricting its development. Therefore, extensive research were devoted to developing mitigation methods for membrane fouling in MBR, including physical, chemical and biological methods. Among them, biological method has been widely concerned because of its advantages such as low cost, environmental friendliness and sustainability. Herein, the biological control methods for membrane fouling mitigation in MBR were systematically classified into quorum sensing/quenching, energy uncoupling, biological enzyme, nitric oxide induction, D-amino acid inhibition, cracking and predation. The latest applications and progress of these kinds of biological methods in MBR were mainly introduced. Moreover, the future research directions of biological methods were prospected according to some problems existing in current researches.
