Fouling Mitigation Strategies in Membrane Bioreactors: A Focus on PVDF Membranes

The effectiveness of membrane bioreactors (MBRs) heavily relies on the mitigation of membrane fouling. PVDF membranes, known for their strength, are frequently used in MBRs but are susceptible to various fouling mechanisms. This article delves into effective fouling mitigation strategies specifically tailored for PVDF membranes, aiming to enhance the longevity and capacity of MBR systems.

Strategies encompass a comprehensive range of approaches, including pre-process methods to reduce foulants in the feed stream, membrane surface modifications to increase hydrophobicity or resist bacterial growth, and process tuning such as flow rate and backwashing frequency. The selection of the most suitable mitigation strategy depends on factors such as the type of foulants, membrane pore size, and specific application requirements.
