Our aeration tubes are an ideal solution for a biofloc culture; our low maintenance solution helps to maintain better DO levels across the ecosystem with the help of bottom up diffusion. For more information check our presentation. Call: +91 - 7285017087

1. Use of AirOxi Tube in Biofloc culture
Experts in Diffused Aeration

3. Key features of Bio Floc Technology (BFT)
• Balancing Caron Nitrogen Cycle
• Recycling nutrients in a natural way
• Minimum water exchange
• High Aeration needed to support bacteria and fish/shrimp

4. Independent study on biofloc aeration
A study on aeration methods for biofloc culture of L. Vannamei
published in Aquaculture International February 2017 found diffused
aeration to be the best aeration method for biofloc
Stocking Density - 40 / sq mt
9 tanks of 35 sq mtr size (4900 pieces per tank)
Initial weight – about 4.5 gram
Study period – 33 days. Result after 33 days
Aeration method Diffused aeration
with Blower
Vertical Pump Propeller aerator
DO – mg /L (Avg) 4.91 4.49 4.50
Final weight (Avg) 12.96 10.93 12.81

5. AirOxi Tube Diffused Aeration System
• Blower based – low power consumption – 1/3rd of Paddle aerators
• Bottom up diffusion – extremely efficient
• Technology used worldwide in ETP / STP / WWTP and aquaculture
• Uniform aeration throughout the pond – top and bottom
• Entire ecosystem gets DO – better autotrophic cycle
• Low Maintenance

6. AirOxi tube – Ideal solution for growout ponds,
biofloc, nursery, RAS and Raceway
• Diffused aeration is the only option for nurseries, biofloc, RAS,
Raceway and IPRS
• AirOxi tube is used all over India in all these types of culture

9. AirOxi Tube is also best solution for large
ponds. Airoxi v/s Paddle aerator in pond use

10. Eventual Benefits to Farmers
Higher and more uniform DO, Faster DO leading to:
• Higher Stocking Density – increase by 40-50%
• Higher Immunity
• Higher Survival – 85% to 95%
• Faster Growth (saving of 10-20 days, even one additional crop/ year)
• Low FCR
• Reduced cost of power used for aeration – saving of 40-60%

12. Measuring Aeration Energy Efficiency
Amount of oxygen transferred
Amount of energy added
Standard Aeration Efficiency (SAE) =
Depending on depth of installation and salinity of
water, AirOxi tube diffused aeration system gives
2 to 3 times dissolved oxygen per HP of power
used, compared to surface aerator
