Today, MBBR technology is used for municipal sewage treatment, industrial wastewater treatment, and decentralized wastewater treatment. This technology has been used in many different industries, some of them being:
* Automotive industry
* Chemical industry
* Food and beverage
* Metal plating and finishing
The MBBR system is considered a biofilm or biological process, not a chemical or mechanical process. Other conventional biofilm processes for wastewater treatment are called trickling filter, rotating biological contactor (RBC) and biological aerated filter (BAF).
Important applications:
* Denitrification
* Nitrification
* BOD/COD removal
* Anaerobic ammonium oxidation (ANAMMOX) process
