Improvements in Hollow Fiber MBR Design for Enhanced Sludge Removal
Membrane bioreactor (MBR) systems have gained widespread adoption 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 affect system efficiency and longevity. Recent research has focused on developing innovative design enhancements for hollow fiber MBRs to effectively combat this challenge and improve overall efficiency.
One promising approach involves incorporating innovative membrane materials with enhanced hydrophilicity, which prevents sludge adhesion and promotes shear forces to separate accumulated biomass. Additionally, modifications to the fiber arrangement can create channels that facilitate sludge removal, thereby enhancing transmembrane pressure and reducing blockage. Furthermore, integrating passive cleaning mechanisms into the hollow fiber MBR design can effectively degrade biofilms and minimize sludge build-up.
