MBR Membrane

MBR membrane modules integrate biological wastewater treatment with membrane filtration, replacing conventional secondary clarifiers with hollow-fiber or flat-sheet membranes rated at 0.1-0.4 um. This combined process achieves superior effluent quality with virtually zero suspended solids, enabling direct water reuse. PVDF hollow-fiber MBR membranes operate at low transmembrane pressures (0.01-0.05 MPa) with flux rates of 10-25 LMH, delivering stable performance across municipal and industrial wastewater applications.

Key advantages:

• Effluent quality: turbidity < 1 NTU, SS near zero, suitable for direct reuse

• 50%+ footprint reduction vs. conventional activated sludge processes

• High MLSS concentration (8,000-12,000 mg/L) improves biodegradation efficiency

• Low sludge production reduces disposal costs significantly

• Modular design allows incremental capacity expansion without major retrofit

Typical applications: Municipal wastewater plants, food and beverage factories, pharmaceutical facilities, textile mills, residential complex sewage systems

FAQ:

Q: How often do MBR membranes need cleaning?

A: Routine backwash every 10-30 minutes; CIP every 1-3 months depending on MLSS concentration and operating flux.

Q: What is the typical membrane lifespan?

A: PVDF MBR membranes last 3-5 years with proper maintenance and cleaning protocols.
