CFIC® is a second-generation moving bed bioreactor (MBBR). The major advance with CFIC is that the downstream settlement stage is no longer required, making the installation more compact and cheaper to install.
CFIC is based upon established MBBR principles but uses a high packing density so the media cannot move freely. Solids are trapped within the media, so biological treatment and solids separation take place within a single compact reactor. Periodically the outlet is closed off and the water level is raised, allowing the media to move freely. The accumulated solids are flushed out, then the water level is lowered again and the plant returns to filtration mode.
The effluent from CFIC can be discharged directly or passed through a filtration stage, such as FilterClear, to achieve the tightest discharge limits.
- Low effluent TSS concentration
- Controlled sludge wasting
- No recirculation needed
- Treatment and solids separation in a single, compact reactor
- Suitable for municipal wastewater and industrial effluent treatment
CFIC was developed by Biowater Technology of Norway, whose staff developed the original Kaldnes MBBR media. Bluewater Bio has a global non-exclusive licence for CFIC.
