Moving Bed Biofilm Reactor (MBBR)
- Efficient Biomass Retention: MBBR systems use plastic carriers to support biofilm growth, allowing for a higher concentration of biomass compared to CAS systems. This results in more efficient pollutant removal.
- Reduced Footprint: Due to the higher biomass concentration, MBBR systems require smaller reactor volumes, making them ideal for space-constrained locations.
- Operational Stability: MBBR systems are less sensitive to fluctuations in influent quality and hydraulic loading, providing more stable treatment performance.
- Low Maintenance: The media sloughs excess biomass as needed which simplifies operation and maintenance, reducing the risk of clogging and the need for frequent cleaning.
- Energy Efficiency:
- Superior Effluent Quality: MBR systems combine biological treatment with membrane filtration, producing high-quality effluent with low levels of suspended solids, bacteria, and pathogens.
- Space-Efficient Design: The integration of membranes allows for compact system design, making MBRs suitable for urban and decentralized applications.
- Flexibility: MBR systems can handle variable influent loads and concentrations, ensuring consistent performance even under challenging conditions.
- Enhanced Biomass Retention: The use of membranes in MBR systems enables high biomass concentrations, improving the overall treatment efficiency and reducing sludge production.
- High Settling Velocity: GAS granules have a higher settling velocity compared to conventional flocs, allowing for more efficient solid-liquid separation and reducing the need for large settling tanks.
- Enhanced Nutrient Removal: The unique structure of GAS granules promotes the coexistence of aerobic and anaerobic zones, facilitating simultaneous nitrification-denitrification and phosphorus removal.
- Compact System: The high biomass concentration in GAS systems allows for smaller reactor volumes, making them suitable for space-limited installations.
- Improved Stability: GAS systems exhibit high resilience to shock loads and toxic compounds, maintaining stable performance under varying operational conditions.
