What are the advantages of hollow fiber membrane bioreactors(MBR) in wastewater treatment?
As the advantages of hollow fiber membrane bioreactors in wastewater treatment become increasingly apparent, their usage in wastewater treatment is also becoming more widespread. Next, let us unveil the five core advantages of hollow fiber membrane bioreactors in wastewater treatment.

1. Modular Design: Flexible like Building Blocks
2. Efficient Separation: Turning Sewage into Clear Water
MBR filters wastewater through micropores (0.1-0.4μm) to intercept suspended solids, bacteria, and viruses. Effluent quality exceeds Class A of GB 18918-2002, suitable for reuse.3. Anti-Fouling Performance: Less Maintenance
Membrane sheets made of PVDF with air scouring technology prevent sludge blockage. Cleaning cycles can be extended to 90 days (3x longer than traditional membranes), reducing maintenance costs and labor.4. Energy and Cost Efficiency
MBR reduces energy consumption by 20-30% through low sludge concentration operation. Membrane modules last 5-8 years, minimizing replacement costs and carbon emissions.5. Intelligent Control: Automated Operation
Real-time monitoring adjusts aeration and backwashing automatically. Chemical cleaning is triggered when fouling is detected, ensuring optimal operation without manual intervention.Real Case: Upgrading a Municipal Wastewater Plant
