Biodrum Rotators | Drum filters with a Rotating biological section

The MPF BiodrumRotator

is our top model among the Biodrum filters! This model is a major upgrade over a standard Biodrum. The moving bed has been replaced here by a Rotating Biological Drum (RBC). The RBC is standard filled with Helix as a bio-media. This can also be filled with other biological material if desired.

The RBC is a rotating trickle / drip filter concept that requires no feed height from the pump! The RBC is 40% underwater and 60% above water for the maximum ammount of oxygen saturation. The big secret of this design is that the oxygen values are higher then in other filters, up to 4% higher in the water and 20% higher in the air. This gives the pond bacteria the best conditions to perform their work efficiently.

The rotating movement of the RBC ensures that a trickle / drip filter is created without feed height. The industrial motor of 250nM and 60 watts turns the RBC.

Ammonia and nitrite removal:

Scientific studies in fish farming have shown that an RBC guarantees a very high ammonia and nitrite removal, 50% better than trickle filters and many times better than moving bed / mat filters!

Benefits :

• Better biological filtering effect
• No more feed height compared to a trickle filter
• 2x as efficient as a moving bed
• Faster start-up than a moving bed
• No drop in water temperature in winter compared to trickle filters
• No noise
• More stable bacterial culture even during the use of medication and changing water values
• No need for an air pump anymore
• Water is of better quality
• You can feed more
