Membrane Fouling Mitigation Strategies in MBR Systems
Membrane fouling presents a major challenge in membrane bioreactor (MBR) systems, leading performance deterioration and increased operational costs. To mitigate this issue, various strategies have been developed. These strategies can be grouped into physical, chemical, and biological approaches. Physical methods involve membrane modifications, such as using antifouling materials or implementing backwashing techniques to reduce accumulated fouling layers. Chemical methods concentrate on the use of chemicals to break down foulants, while biological approaches aim to enhance microbial activity to compost organic matter. A combination of these strategies often proves to be the most successful for achieving sustained MBR performance and minimizing fouling impacts.
