Fouling Control in Membrane Bioreactors: Challenges and Mitigation Techniques

Membrane bioreactors (MBRs) present a promising strategy for wastewater treatment due to their high efficiency and reduced footprint. However, fouling represents a significant hindrance to their long-term operation and performance. Fouling is the accumulation of organic and inorganic substances on the membrane surface, leading to decreased permeability and increased operational costs.

Several factors contribute to fouling in MBRs, including high concentrations of suspended solids, dissolved inorganic matter, and microbial growth. This build-up of foulants reduces the membrane's ability to effectively separate pollutants, ultimately impacting the quality of treated water.

To mitigate fouling in MBRs, a range of approaches have been utilized. These include:

• Alterations to membrane structure such as using antifouling materials to reduce the adhesion of foulants.
• Upstream treatment methods to remove suspended solids before they reach the membrane.
