Developments 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 impair system efficiency and longevity. Recent research has focused on developing innovative design enhancements for hollow fiber MBRs to effectively address this challenge and improve overall efficiency.
One promising method involves incorporating novel membrane materials with enhanced hydrophilicity, which prevents sludge adhesion and MBR promotes shear forces to remove accumulated biomass. Additionally, modifications to the fiber structure can create channels that facilitate wastewater passage, thereby improving transmembrane pressure and reducing fouling. Furthermore, integrating active cleaning mechanisms into the hollow fiber MBR design can effectively degrade biofilms and prevent sludge build-up.
These advancements in hollow fiber MBR design have the potential to significantly enhance sludge removal efficiency, leading to improved system performance, reduced maintenance requirements, and minimized environmental impact.

Influence of Feed Water Characteristics on PVDF Membrane Fouling in MBRs
The performance and longevity of membrane bioreactors (MBRs) are significantly affected by the quality of the feed water. Incoming water characteristics, such as total solids concentration, organic matter content, and amount of microorganisms, can cause membrane fouling, a phenomenon that obstructs the permeability of water through the PVDF membrane. Accumulation of foulants on the membrane surface and within its pores reduces the membrane's ability to effectively separate water, ultimately reducing MBR efficiency and necessitating frequent cleaning operations.
Sustainable Solutions for Municipal Wastewater: Hollow Fiber Membrane Bioreactors
Municipal wastewater treatment facilities are challenged by the increasing demand for effective and sustainable solutions.
