Results at Fingerlakes Aquaculture - Groton, NY
(External link)
Ozone Solutions was asked to design a system to incorporate ozone into a
Talapia fish farm. Ozone was injected into two U-tubes and distributed to
eight fingerling tanks to improve water quality.

MinAqua Fish Farm - raise 1.7 million lbs of Talapia per year.
Fish are sold live to markets across the US and Canada. |

Shed for protecting ozone generator |
 |
Ozone Generator with ozone sensor and exhaust fan. Ozone generator
creates 24-lb/day of ozone. Exhaust fan starts upon
detection of leaking ozone. Grey box is a transformer for ozone
generator. |
 |
Empty fingerling tank (3,500-4,000 gallons). Each can hold up to
90,000 fingerlings. A total of eight tanks were supplied
with ozone. |
 |
U-tube set-up along with ozone injection apparatus. Two U-tubes
shown. One U-tube
supplies water, oxygen and ozone for four tanks. |
 |
Control panel for balancing ozone to each U-tube. Panel contains
flowmeters, pressure gauge and dump valve. |
 |
Ozone injection into U-tube. Ozone Compatible line ensures long
life. Check valve ensures no water enters line when ozone production
is terminated. |
 |
Ozone and oxygen recovery system. Gases are vented from top of U-tube
and injected into water stream with a venturi. |
 |
Ozone display with two alarm set-points. The first set-point is at
0.25-PPM and triggers an intermittent alarm. The second set-point is at
0.50-PPM and turns on the fan in the shed to remove ozone before personnel
entry. Sensor display is located in a high traffic area. |
