Improvements in Hollow Fiber MBR Design for Enhanced Sludge Removal
Membrane bioreactor (MBR) systems have gained widespread acceptance in wastewater treatment due to their superior performance in removing organic matter and suspended solids. However, the formation of sludge within hollow fiber membranes can significantly reduce system efficiency and longevity. Recent research has focused on developing innovative design enhancements for hollow fiber MBRs to effectively mitigate this challenge and improve overall performance.
One promising method involves incorporating novel membrane materials with enhanced hydrophilicity, which minimizes sludge adhesion and promotes shear forces to separate accumulated biomass. Additionally, modifications to the fiber arrangement can create channels that facilitate wastewater passage, thereby enhancing transmembrane pressure and reducing clogging. Furthermore, integrating passive cleaning mechanisms into the hollow fiber MBR design can effectively remove biofilms and avoid sludge build-up.
