Moving Bed Biofilter Reactors (MBBR)

Moving Bed Biofilter Reactors (MBBR)
MAT MBBR filters are made of PP plastic and they are designed to create proper media swell, allowing maximum bacteria oxygenation with minimal backwash requirements. Filled with floating biomedia will provide optimum biological filtration support . MAT MBBR are equipped with venturis & come fully installed and hydrotested.


MBBR are biological filters, fabricated to provide biological filtration and maximize oxygen concentration while enabling organic load degradation. MBBR biotowers, are made of PP, resistant to osmosis and ozone gas. MBBR range covers the treatment needs for Biomass load from 10 up to 850kg per bio-tower, utilizing low water volume and small footprint. The non-treated water swell is continuously mixed with air/oxygen in the biotower, while the organic load is degraded biologically by microorganisms. This bio-film layer is formed on and in suspended polyethylene floating media.

Our Moving Bed Biofilter Reactor is a tested and proven biological filtration solution that allows high oxygen concentration and excellent TAN removal at the smallest possible footprint.

MAT MBBR is applicable to any biologically charged water volume and it is commonly used to fresh and marine RAS farms and hatcheries.


The Moving Bed Biofilter Reactor retains the organically charged water by creating a vortex, to evenly move the bio media into the highly oxygen saturated contact chamber. This retention allows the microorganisms to biologically absorb the nutrients off the water at a higher level than a traditional trickle filter.

The PE bio-balls provide on their surface the optimum environment for the biofilm layer growth and activity. The activity of the micro-organisms biofilm conversion of the organic load to NO3 is enhanced by continuous air/oxygen infusion into the moving bed reservoir. MAT integrated MBBR design optimizes the air mixing process through high pressure air injection and fine air bubble subsequent formulation.


  • Advanced Reactor design, Robust and Proper for saline and fresh water
  • Improved biological reactor for aquaculture facilities
  • Long Lasting Polyethylene moving bed media
  • Better biological filtration than trickle filter
  • Ease in operation & maintenance
