Membrane Fouling in MBR Systems: Mitigation Strategies and Challenges
Membrane fouling poses a major challenge in membrane bioreactor (MBR) systems. This phenomenon, characterized by the accumulation of organic matter, inorganic solids, and microbial cells on the membrane surface and within its pores, can lead to reduced permeate flux, increased operating costs, and diminished system read more efficiency.
