 OXYGENATION: an effective approach (1)
Important informations about the equipments dissolving oxygen for aquaculture: :
A reactor under pressure as cones, Aquavi ... allows to dissolve R = 0.5 to 0.7kg oxygen / Kwh
A jets platform or OXYFOX-PJ if used with a pump can achieve R = 1.0 to 1.4Kg oxygen / Kwh
An OXYFOX treating up to 400 liters/s reaches R = 2.0 to 2.5kg oxygen / Kwh
"U" Tube calculated by FOX offers the best ratio known to day R = 3.5 to 4.5kg oxygen / Kwh
These values are given as an indication for water at 14 ° C and a yield of dissolution over 85%. (+or- 5%).
|
range OXYFOX with peripheral outlet: O2 output up to 300% oxygen saturation of 85% yield, R = 2.4
|
 |
 |
 |
Oxyfox 8kg 02 /h – one pumpe |
Oxyfox 16kg 02 /h – two pumps
|
Oxyfox 25kg 02 /h – two pumps
|
range OXYFOX with outlet by pipes: O2 output up to 300% oxygen saturation of 85% yield, R = 2.0
|
 |
 |
 |
Four OXYFOX connected two by two and giving globaly to the ponds 90 kg/h oxygen |
|
OXYGENATION : effective approach (2)
Range OXYFOX-PJ: oxygen level outlet up to 220% of saturation efficency 85% R=1,0 to 1,4 |
 |
 |
 |
Oxyfox-PJ 1,0 kg 02 /h |
8 OXYFOX-PJ 6,0 kg/h concrete made |
Oxyfox-PJ 4,5 kg 02 /h |
 |
 |
 |
Oxyfox-PJ 60 kg 02 /h |
2 Oxyfox-PJM with pumps 5,0 kg 02 /h |
Oxyfox-PJM with pumps 8 kg 02 /h |
 |
|
|
Oxyfox-PJ 7,0 kg 02 /h |
|
|
OXYGENATION :an effective approach (3)
The cones and OXYFLOW reactors : outlet oxygen level up to 320% of saturation, pressure service 0,5 bar , efficency 95% R= 0,6
 |
 |
 |
 |
Bicône 7 kg 02/h |
Bicône 12 kg 02/h |
Oxyflow 3.5 kg 02/h |
Oxyflow 7.5 kg 02/h |
|
|
The U-tubes with recycled gases: outlet oxygen level up to 500% of saturation R= 3,5 to 4,5
|
The U tube is built in the ground, so it’s difficult to make photos.
References we have, show significant amounts of oxygen transferred,
depending of course on the depth of the wells, and the quality
of the recycled gases
Some samples:
Well 18 m deep, treating 250 liters/s of fresh water allows to reach outlet
oxygen level at 40 mg/l , with 85% efficency.
Well 5 m deep, treating 150 liters/s of fresh water reaches outlet
oxygen level at 25 mg/l , with a good efficency.
a personalized study is necessary .

130% nitrogen saturation inletfishfarm: 8000 L / s degassed and
oxygenated with 40 modules of 200 L / s
cones stopped = large profitin energy and maintenance

|
130% nitrogen saturation inlet fishfarm: 2000 L / s degassed and
oxygenated with 13 modules
cones stopped = large profit in energy and maintenance
|
nitrogen in excess: 300 L / s pushed out
from a well, degassed and oxygenated
|
NITROFOX: hydraulic saturometer, to know the % of nitrogen saturation in continuous (patented) this is the tool for automating the gassing of nitrogen
