Price : Based on processing capacity, water source, processing target
Data : By survey form
• Invented and initially developed in late 1980s at Norway
• 800 MBBR installed on year 2014 – Spread in 50 countries
• Widely used because of the small footprint
The MBBR system consists of a tank (similar to an anaerobic and aerobic activated sludge tank) with special plastic carriers that provide a surface where a biofilm can grow.
These solutions significantly increase the capacity and efficiency of existing wastewater treatment plants, while minimizing the size of new plant deployments.
Wastewater Constituents and Unit Operation and Processes for their Removal
Biodegradable Organics : Aerobic and anaerobic suspended growth variations; Aerobic and anaerobic attached growth variations; Lagoon variations; Advanced oxidation; Membrane filtration; Chemical oxidation.
**Not only can remove BOD and COD but also can do Nitrification and Denitrification Process
- Use special carrier elements for bigger surface area to colonize by bacteria
- When the suspended porous biofilm carriers are continuously mixed in operated aeration tank, active biomass will grows into biofilm on the surface of these carriers.
- Biofilm thickness is maintained and controlled by continuous sloughing created by the aeration-mixing process
- Secondary clarification is typically used
- There is no recycle activated sludge sent back into the process
