Biofloc aeration is different from aeration in growout ponds in 3 very distinct ways
- Aeration required is intense because the BOD (Biological Oxygen Demand) is substantially higher due to probiotics and phytoplankton that feed on the sludge – to ensure the carbon-nitrogen cycle is balanced. The dissolved oxygen required is hence quite high as compared to growout ponds
- Usually, Biolfoc aquaculture is done in tanks or small-sized ponds, often indoors or covered in shade, in order to manage them better. This results in a smaller surface area of the water exposed to the atmosphere and hence the natural dissolution of oxygen is less, so artificial aeration needs to be much more than in growout ponds, and yet the traditional methods of paddlewheel aerator or
- The floc needs to be constantly moved and the water movement needed is high. So the diffused aeration needs to also agitate the water. Hence the diffused aeration system cannot be very fine as done in hatcheries, otherwise, it may give good dissolved oxygen but still, the performance may not be suitable for BFT
Armed with this information AirOxi has developed and launched 3 special aeration tubes:
1. AirOxi NC – 16 mm
2. AirOxi Star
3. AirOxi Xtra
