MBBR Media – Advanced Biological
Treatment for Wastewater Systems
MBBRMedia
is a high-performance biofilm support material used in Moving Bed Biofilm
Reactor (MBBR) systems for the treatment of municipal and industrial
wastewater. The media provides a large surface area for the growth of
microorganisms that biologically degrade organic pollutants, ensuring highly
efficient and stable treatment processes. Designed for continuous operation,
MBBR media helps achieve high removal rates of biochemical oxygen demand (BOD),
chemical oxygen demand (COD), ammonia, and nitrogen compounds, while minimizing
space requirements compared to traditional treatment methods.
With
its robust design and excellent hydraulic performance, MBBR media has become an
essential component in modern wastewater treatment systems, enabling facilities
to meet strict discharge standards and sustainability goals.
What is MBBR Media?
MBBR
Media consists of small, lightweight, high-density plastic carriers that
provide extensive surface area for the attachment of biofilm. These carriers
are suspended in a reactor, where wastewater flows around them. Microorganisms
form biofilms on the media surfaces, consuming organic matter and nutrients
present in the water. The constant movement of the media within the reactor
ensures uniform distribution of biofilm, prevents clogging, and allows for
efficient oxygen transfer.
The
media is typically made from high-density polyethylene (HDPE), polypropylene(PP), or other durable polymeric materials that are resistant to chemicals,
UV radiation, and mechanical wear. The design includes features such as internal
fins, holes, and high surface-to-volume ratio, which maximize microbial
attachment while allowing excellent fluid flow and mixing.
Working Principle
The
MBBR system works on the principle of biofilm-based biological treatment:
- Media Suspension: The reactor is filled with
MBBR media, which floats and moves freely in the wastewater.
- Biofilm Growth: Microorganisms attach to
the media surface, forming a biofilm layer that degrades organic
pollutants.
- Aeration or Mixing: Air diffusers or mechanical
mixers provide oxygen and keep the media in motion, preventing dead zones
and ensuring even microbial activity.
- Pollutant Removal: The biofilm metabolizes
organic matter, ammonia, and nitrogen compounds, producing treated
effluent with low BOD, COD, and nitrogen levels.
- Biofilm Sloughing: Old biofilm detaches
naturally, maintaining an active biofilm layer for continuous treatment.
This
process allows high treatment efficiency without the need for large
sedimentation tanks or complex sludge management systems.
Types of MBBR Media
MBBR
media comes in various shapes, sizes, and configurations to meet different
treatment requirements:
- K1 Media
- Cylindrical carriers with
fins for maximum surface area.
- Ideal for municipal
wastewater treatment.
- Biofilm Disc Media
- Flat or disc-shaped media
suitable for high-flow reactors.
- Ensures excellent oxygen
transfer and biofilm distribution.
- Cylindrical or Tube Media
- Hollow or perforated tubes
that float and rotate within the reactor.
- Optimized for industrial
effluent containing high-strength organic pollutants.
- Custom Engineered Media
Key Features and Benefits
