The BioRotator is a drum filter combined with a continuously rotating biological filter.The key properties at a glance:
over 5x more waste substance breakdown by bacteria compared to so-called moving bed filters*
the biological component ripens faster
suitable for varying fish quantities/feed intensities
no energy loss due to the need to pump water upwards compared to a trickle filter
no air pump -> less nitrogen is dissolved into the water
The BioRotator Compact M comes with:
lid
control electronics
Moving Bed Hel-X 17mm
The Compact Medium uses 100 litres of Hel-X 17 as its biological filter material and can process about 35 m3/hour.
A connection for the Super UV is available by default.
The BioRotators are very energy efficient, have compact dimensions, are made of high-quality materials and are completely automated. They can be entirely dug in and can also be used in a pump-fed setup. UV lamps can easily be mounted in the casing. About 60% of the biological component is above the surface of the water, in an oxygen-rich environment (20% compared to a maximum of 4% oxygen in water). This ensures optimal oxygen saturation.The effect of a trickle filter is imitated without the need to pump water upwards.
Where 100 litres of Hel-X in a moving bed can break down about 16 grams of food/day, a BioRotator breaks down about 80 grams/day*.
An air pump is not required for this filter type, which significantly reduces the negative effect of dissolving nitrogen in water. Since the biological filter material is surrounded by far more oxygen, the filter ripens faster and more efficiently. This also makes fluctuations in feed intensity easier to handle. Ammonia and nitrite are removed more quickly and more effectively compared to filters with fully submerged filter material. After use of a BioRotator, the water is richer in oxygen. On top of that, it contains fewer anaerobic (harmful) bacteria. The BioRotator is a high-grade total solution for Koi and swimming ponds with a maximum flow of 50m3/hour.
Method:
The water flows into the drum sieve, where any dirt larger than 70 microns (0.07mm) is removed. A water level sensor measures whether enough water flows through the drum. If the drum sieve becomes overly clogged, an automatic flushing programme is activated. The collected dirt is automatically removed from the sieve by means of the high-pressure pump and transported to the sewer via nozzles and a flushing channel.
For the Compact models, both the biological component and the drum filter continuously rotate: they are connected. The benefit of this is that only a single motor is required and that the entire surface of the drum filter can be used to collect dirt. Normally, only about half the surface is submerged and available for dirt collection. This results in a lower flushing frequency and reduced water consumption.
