An Examination of Hollow Fiber and Traditional MBR Systems

Membrane bioreactors (MBRs) are widely utilized in wastewater treatment due to their superiority in removing organic matter, nutrients, and suspended solids. Traditionally MBR systems have employed flat-sheet membranes, but hollow fiber membranes have emerged as a promising alternative. This study presents a comparative analysis of hollow fiber and traditional MBR systems, evaluating their performance characteristics, including removal efficiency, hydraulic loading rate, membrane fouling propensity, and energy consumption. The investigation utilizes real-world operational data and laboratory experiments to shed light the strengths and limitations of each system, ultimately providing valuable guidance for implementing optimal MBR configurations for various wastewater treatment applications.

PVDF Membrane Fouling Mitigation in MBR Applications

The effectiveness of membrane bioreactors (MBRs) is significantly affected by the operational stability of the polyvinylidene difluoride (PVDF) membranes. Unfortunately, PVDF membranes are prone to fouling, a process where suspended solids accumulate on the membrane surface and pores, resulting in decreased permeate flux and increased operational costs. Consequently, mitigation of PVDF membrane fouling is essential for optimizing MBR performance and ensuring long-term reliability.

Several strategies have been implemented to mitigate PVDF membrane fouling in MBR applications. These include alteration of operational parameters such as transmembrane pressure, flow rate, and backwashing frequency. Additionally, the use of pre-treatment methods like coagulation, flocculation, and sedimentation can effectively reduce the amount of foulants entering the MBR system.

Furthermore, incorporating membrane treatments such as surface functionalization with antifouling agents can inhibit fouling by modifying the membrane's physicochemical properties and reducing the accumulation of foulants.
