MABR: Clear Advantages over Hollow Fiber
Robust, energy-efficient, and lower TCO
Fluence MABR Membrane
Robust Design:
-
- Spiral wound membrane configuration less sensitive to biofouling
leading to more stable operations
- Over time, spiral wound membrane configuration displaced
hollow fiber in desalination due to being more robust
Energy Efficient:
- Uses low-pressure air feed compared to hollow fibers
- No scouring required
Low-Maintenance Operation: 30+% less chemical use
• Proven Experience: Over 300 plants demonstrating a wide range of
flows and applications, from 5 m³/d to 20,000 m³/d
⚫ Cost-Effective: 30+% overall lower TCO
