The biodrum rotator 50:

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 The moving bed has been replaced by a Rotating Biological Contactor (RBC). The RBC is filled with Helix as bio-media. This can also be filled with other bio-media material if desired.

The RBC is a rotating trickle / drip filter concept that requires no feed height from the pump! The RBC is 40% under water, and 60% above water for maximum oxygen saturation. The big secret of this design is that the water can contain up to 4% oxygen and the air arround it up to 20%. 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 a feed height. The industrial motor of 250nM of 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 filltering 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 temperature in winter compared to trickle filters
• No noise
• More stable bacterial culture, even with use of medication and changing water values
• No need for an air pump anymore
• Water is of better quality
• You can feed more
