Carbon dioxide (CO2) degassing
The carbon dioxide (CO2) can be in excess in the water at the entrance to a fish farm, or in the re-used water circuits and RAS.
FOX France Oxygenation proposes CO2 degassing solutions adapted to the needs of your fish farm.
CARBOFOX® is one of FOX’s processes for degassing excess CO2 in fish farm water. This process involves injecting air into small bubbles at the bottom of the pond or channel.
CARBOFOX® is calculated to reduce the concentration of dissolved CO2 to a value compatible with fish.
Dissolved CO2 is a weak acid. When dissolved CO2 is degassed, the pH increases. CARBOFOX® can be regulated to stabilize the pH of the water at a desired value.
Nitrogen (N2) degassing
In fish farm, dissolved nitrogen can be in excess in spring water, Recirculating Aquaculture System (RAS) water and when some aeration techniques are used.
FOX France Oxygenation proposes the NITROFOX® device designed to continuously measure the total pressure of gases dissolved in water. This value expressed in mbars and transferable in 4-20 mA form to a monitoring that will calculate the % of dissolved nitrogen using suitable software.
NITROFOX® is installed near a water current, where you want to know the nitrogen content continuously.
With NITROFOX® and its monitoring, a degassing system can be automated to obtain a fixed value of dissolved nitrogen.
Nitrogen degassing systems are proposed by FOX France Oxygenation.
A special feature of NITROFOX®: It is possible to take a gas sample from NITROFOX® representative of the mixture of gases that are dissolved in the water. This is useful when one wants to analyze by gaseous way all the gases dissolved in the water of the site.
