MBBR Technology Revolutionizes Aquaculture and Wastewater Treatment

The Evolution of MBBR: From Fixed Beds to Floating Solutions

In the 1980s, Professor Arne Rovik at Norway’s NTNU pioneered Moving Bed Biofilm Reactor (MBBR) technology to solve fixed-bed flaws: clogging, anaerobic zones, and high maintenance. By 1990, commercial MBBRs from Kaldnes transformed wastewater management with lightweight, porous PE/PP carriers.

How MBBR Works

Key advantages:
✅ Dynamic biofilms for ammonia removal (nitrification) and nitrate reduction (denitrification)

✅ Self-cleaning action prevents sludge buildup

✅ Scalability for RAS and industrial systems

Why MBBR Dominates Aquaculture

• Safety: Eliminates hydrogen sulfide risks (linked to 100+ Norwegian salmon deaths post-2016)

  
  

• Efficiency: 80% ammonia reduction, 30% lower costs in trials

  
  

• Space-saving: Compact design for intensive farming

  
  

Modern Media Innovations

Advanced materials like nano-structured composites enhance:

• Mechanical durability

  
  

• Uniform flow distribution

  
  

• Biofilm retention

  
  

Applications Beyond Aquaculture

MBBRs are used in:

• Municipal wastewater treatment

  
  

• Food/pharmaceutical waste management

  
  

• Stormwater filtration
