What is MBBR Media?

MBBR (Moving Bed Biofilm Reactor) media are specially designed plastic carriers that provide a large surface area for beneficial bacteria to grow and form biofilms. These carriers move freely in the aeration tank, providing superior treatment efficiency in a compact system.

Types of MBBR Media

We offer various types and sizes of MBBR media:

  • K1 Media: Cylindrical design with internal fins
  • K3 Media: Wheel-shaped design with protected surface
  • K5 Media: Advanced design for maximum surface area
  • Custom Media: Tailored designs for specific applications

Key Features

  • High specific surface area (500-900 m²/m³)
  • Made from high-density polyethylene (HDPE)
  • Designed density for optimal movement
  • Long service life (10+ years)
  • Chemical and temperature resistant
  • Protected internal surface area
  • UV stabilized

How MBBR Media Works

The media carriers are added to the aeration tank at 40-70% fill ratio. As they move freely with aeration, beneficial bacteria colonize the large surface area, forming biofilms that efficiently digest organic matter and nutrients from the wastewater.
