text: 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
