Moving Bed Biofilm Reactor (MBBR) technology combines activated sludge efficiency with biofilm reactor simplicity for compact, efficient wastewater treatment.

How MBBR Works

Small plastic carriers with biofilm grow inside an aerated tank. Carriers are retained by a screen at the outlet. No sludge recycling required.

Key Advantages

• High efficiency: High biomass concentration (4-6 g/L)
• Compact: 50-70% smaller than conventional activated sludge
• Simple operation: No sludge recycling or return
• Flexible: Easy capacity expansion
• Robust: Handles shock loads and toxic events

Applications

• Municipal wastewater treatment
• Industrial wastewater pretreatment
• Nutrient removal (nitrification, denitrification)
• Separate stages for different processes

Carrier Media Options

• HDPE carriers (standard applications)
• PU carriers (for specific industrial conditions)
• High-surface-area designs for nitrification
