Technical Specifications
AquaNit Tricking Biofilter 
- Trickling biofilters are among the first bio-reactors used for wastewater treatment, and more recently for aquaculture for raising food, game and ornamental fish.
- Simplicity, economy, low operating costs and excellent contact with air were always the main elements that ranked these biofilters high on the scale.
- Selected for its high electrostatic affinity, the media filling our AquaNit biofilters attracts bacteria. The biofilm attaches itself rapidly, providing a stable environment for the fish more rapidly than most other plastic media.
High quality and performance!
It has been our experience that Aquanit Trickling Biofilters
are excellent biofilters;They allow exceptionally high levels of water recirculation, even at high fish densities;
These bioreactors are nearly maintenance-free, they are extremely reliable and easy to work with.
Gain confidence on biofilter's nitrifying capability in little time!
Our biofilters are activated with active freshwater or marine nitrifying bacteria before delivery.
This unique feature saves a tremendous amount of biofilter maturation time, technical personnel time, and protects your fish against ammonia peaks during the first months.
Aquabiotech is at the the forefront of innovative water filtration technology. Delivered with a unique pre-activated biofilter, aquabioLab's equipment saves time, money. while protecting fish against ammonia spikes.
Your personnel will learn how to reactivate the nitrifying population when the system arrives at your facility, so that when fish is added, the active nitrifying population will be immediately active, keeping ammonia and nitrite levels down right from the first days.
You will learn our procedure for feeding the Biofilter with the included ammonia making sure its nitrifying bacterial population has recovered from transit, and has adapted to your operating conditions;
With this one to two week process you will gain confidence on the Biofilter's capacity to fully keep ammonia and nitrite levels down, even in cold seawater, once the fish are added;
Our operating instruction manual also provides maintenance instructions and tips on water quality guidelines for shellfish holding, biofilter re-activation and storage.
| Advantage | Suitability to Application |
| Self-cleaning | No backwash is required;
|
| Absence of flow limitation within the bio-reactor – the biofilter can take nearly unlimited flow rate; | Important in regard to system management: flow rates can be increased to supply growing oxygen demand as fish density increases without limitations imposed by the biofilter; |
| Low operating pressure | Reduces pumping costs. The water needs simply to be pumped to the top of the biofilter. It then trickles down through the media without pressure build-up. |
| No gradual reduction of water flow across the biofilter | Very important for operator peace of mind. As there is no gradual clogging, the flow rate across the biofilter remains constant, nor is there any variation in water exchange rates within the fish tanks. |
| Very light media with electrostatic affinity for bacterial cells; supports high pressures | Reduces transportation costs. Easy to manipulate. Rapidly and efficiently coated with nitrifying bacteria. Resists compacting. |
| Biofilter provides excellent oxygenation and degassing | Prevents Nitrogen Supersaturation in closed systems Enhanced security of biofiltration process through:
|
| Negligible water loss | Are ideal for closed systems |
