  • What is moving bed biofilm reactor (MBBR)?
  • Moving bed biofilm reactor (MBBR) is a continuous completely mixed biofilm reactor used for various treatment purposes in both municipal and industrial wastewater.
  • What is MBBR wastewater treatment?
  • MBBR combines many of the strengths of biological processes, specifically anactivated sludge process and biofilm media, while eliminating or minimizing the shortcomings that tend to come with biological processes for wastewater treatment. Because of the many benefits it offers, MBBR has become a popular mode of biological wastewater treatment.
  • How is MBBR biofilm developed?
  • In MBBR biofilm is developed on moving plastic carrier/media of low density and carrier movement within the reactor is attained by aeration or by a mechanical stirrer under aerobic and anaerobic conditions, respectively (Abdelfattah et al. 2020 ). Microbial growth takes place in the form of biofilm on the MBBR carrier surface.
  • Can MBBR be used to treat synthetic wastewater?
  • Zafarzadeh et al. ( 2010) came out with a study using MBBR based on anoxic and aerobic reactors for the treatment of synthetic wastewater containing glucose and ammonium filled with 40 and 50% (v/v) with K1 biofilm carriers, respectively.
