Moving Bed Bio Reactor (MBBR)

Moving Bed Biofilter Reactor (MBBR)

The Moving Bed Bio Reactor (MBBR), also known as the Moving Bed Biofilter Reactor, not only enhances water quality but also ensures efficient biological treatment for aquaculture, hatcheries, and Recirculating Aquaculture Systems (RAS). Moreover, since the system provides continuous biological filtration, it maximizes oxygen concentration while simultaneously degrading organic loads with high efficiency.

In addition, our MBBR biotowers are constructed from premium-grade polypropylene (PP), which guarantees resistance to osmosis, corrosion, and ozone exposure. Furthermore, their innovative design accommodates biomass loads ranging from 10 kg to 850 kg per biotower; therefore, they remain suitable for both small-scale and large-scale operations.

As water flows through the MBBR, aeration or pure oxygen maintains constant circulation. Consequently, microorganisms colonize the suspended polyethylene floating media and develop a stable biofilm layer. This biofilm effectively breaks down organic waste and removes Total Ammonia Nitrogen (TAN), ensuring balanced water chemistry.

Because of its compact footprint and low water volume requirement, the MBBR proves highly efficient for modern aquaculture facilities. Additionally, it delivers high oxygen transfer rates, superior TAN removal, and consistent water quality for both freshwater and marine biofilter applications.

Ultimately, whether applied in intensive RAS farms, commercial hatcheries, or research facilities, Pureflow’s MBBR system provides unmatched biological filtration, promotes healthier aquatic life, and reduces long-term operational costs.

Key Benefits of Our MBBR Systems

High Oxygen Concentration – Maximizes oxygen transfer for optimal microbial activity.
Superior TAN Removal – Effectively reduces ammonia and nitrite levels.
Compact Footprint – Saves valuable space without compromising performance.
Durable PP Construction – Long-lasting and resistant to corrosion, osmosis, and ozone.
Scalable Design – Fits both small ornamental fish farms and large commercial operations.
Low Maintenance – Self-cleaning motion of media reduces clogging and downtime.

How MBBR Works?

In the MBBR process, specialized floating bio-media not only provide a large surface area for bacterial colonization but also enhance biological activity for effective wastewater and aquaculture treatment. Moreover, because aeration continuously keeps the media in motion, water, oxygen, and bacteria remain in constant contact. In addition, this ongoing movement maximizes nitrification efficiency while preventing clogging. Furthermore, since the system is inherently self-cleaning, operators benefit from low-maintenance performance and long-term reliability. Ultimately, MBBR technology ensures stable water quality, improved biosecurity, and sustainable treatment efficiency for aquaculture facilities, RAS units, and wastewater applications.

Frequently Asked Questions (FAQ)

1. What is the purpose of an MBBR in aquaculture?

An MBBR maintains water quality by biologically filtering harmful ammonia and nitrites, creating a safe habitat for fish.

2. How often should I clean my MBBR system?

Because the bio-media is self-cleaning, manual cleaning is minimal. Periodic inspection is recommended every few months.

3. Can MBBR be used in freshwater and saltwater systems?

Yes, Pureflow MBBRs perform efficiently in both freshwater and saltwater marine biofilter environments.

4. What size MBBR do I need for my pond or tank?

The required size depends on water volume, fish stocking density, and bio-load. Our team can recommend the ideal model.

5. Does the MBBR require chemical additives?

No, MBBRs operate naturally, relying on beneficial bacteria for water purification without chemicals.
