Fouling Control in Membrane Bioreactors: Challenges and Mitigation Techniques
Membrane bioreactors (MBRs) present a promising solution for wastewater treatment due to their high efficiency and reduced footprint. However, fouling represents a significant challenge to their long-term operation and performance. Fouling is the accumulation of organic and inorganic components on the membrane surface, leading to decreased permeability and increased operational costs.
Numerous factors contribute to fouling in MBRs, including high concentrations of suspended solids, dissolved biological matter, and microbial growth. This accumulation of foulants impedes the membrane's ability to effectively separate contaminants, ultimately impacting the quality of treated water.
To mitigate fouling in MBRs, a range of techniques have been utilized. These include:
- Modifying membrane architecture such as using self-cleaning materials to reduce the adhesion of foulants.
