Moving Bed Bioreactor

Certifications & Memberships

Moving bed bioreactor (MBBR) technology is simple to operate, has a compact footprint and increases capacity. It is a biological system that uses plastic (HDPE) media to support attached growth biofilms. Due to the high biomass concentration, it achieves efficient biochemical oxygen demand (BOD) and ammonia removal. MBBR is ideally used with dissolved air flotation (DAF) clarifiers contributing to an even smaller footprint and improved effluent quality.

  • Robust, proven technology
  • Available in a variety of configurations, depending on treatment objectives
  • Seamlessly integrates with other AWC treatment steps (pre-treatment, clarification, etc.)
  • Improves clarifier performance with no return activated sludge
  • Suitable for high BOD applications
