MBBR
Overview
The Moving Bed Biofilm Reactor (MBBR) is an advanced biological wastewater treatment technology that combines the advantages of activated sludge and biofilm processes. By utilizing specially designed biofilm carriers suspended within the reactor, the system achieves efficient removal of organic pollutants and nutrients while maintaining stable performance under varying operating conditions.
Typical Applications
- Municipal Wastewater
- Food Processing Wastewater
- Brewery Wastewater
- Dairy Wastewater
- Textile Wastewater
- Chemical Wastewater
- Pharmaceutical Wastewater
- Industrial Park Wastewater

Working Principle
The MBBR system uses floating biofilm carriers that move freely within the aeration tank. Microorganisms grow on the carrier surface and form a biofilm layer.
As wastewater passes through the reactor, pollutants are biodegraded by the attached microorganisms. Continuous aeration keeps the carriers in motion, ensures oxygen transfer, and maximizes contact between wastewater and biomass.
The treated water then flows to a secondary clarification stage where remaining suspended solids are separated.
Key Benefits
High Treatment Efficiency
The MBBR process provides excellent removal of COD, BOD, ammonia nitrogen, and suspended solids through high-density biofilm growth on carrier media.
Compact Footprint
Higher biomass concentration allows for smaller reactor volumes compared to conventional activated sludge systems.
Strong Shock Load Resistance
The attached biofilm offers stable performance under fluctuating wastewater quality and hydraulic loading.
Easy Expansion and Retrofit
Existing treatment plants can be upgraded by simply adding biofilm carriers and aeration systems.
Low Sludge Production
Reduced excess sludge generation helps lower disposal and operating costs.
Simple Operation
The process requires minimal operator intervention and offers reliable long-term performance.
