MBBR Wastewater Treatment: High-Efficiency Biological Solution
The Moving Bed Biofilm Reactor (MBBR) is an advanced biological wastewater treatment process that combines the strengths of activated sludge and biofilm technologies. Its patented suspended carriers enable highly efficient organic and nutrient removal, making it ideal for municipal and industrial applications.
Juntai MBBR Advantages
40-60% smaller footprint vs. activated sludge (no secondary clarifier required)
30% lower energy consumption with optimized aeration systems

Design Considerations
Carrier Selection Criteria
Density: 0.94-0.98 g/cm³ (for optimal fluidization)
Shape: Cylindrical vs. cross-structured (affects biofilm development)
Fill Ratio: 35-50% for most municipal applications
Aeration System Design
Fine bubble diffusers (SOTE ≥ 30%)
Airflow: 20-40 Nm³ air/m³ carrier·hour
Process Control Parameters
DO: 2.0-3.5 mg/L (aerobic zones)
Temperature: 12-35°C (optimal range)
pH: 6.5-8.0 (for nitrification)
Industrial Applications
✔ Municipal WWTP Upgrades: Capacity expansion without infrastructure modification
✔ Food & Beverage Wastewater: Effective for high-strength organic loads (COD > 5,000 mg/L)
✔ Pharmaceutical/Chemical: Degrades complex compounds via specialized biofilms
