Experts in Diffused Aeration
Use of AirOxi Tube in Biofloc culture
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
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

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

Measuring Aeration Energy Efficiency Amount of oxygen transferred
Standard Aeration Efficiency (SAE) = Amount of energy added
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
