Aquaculture
Ozone increasing productivity in our RAS system
Aquaculture is a critical element of seafood production, and its importance will increase to supply the growing human population. The advantages of RAS (recirculating aquaculture systems) is the ability to select the location, more efficient usage of water, increased environmental control and lower volumes of effluent.
Even with all the advantages that aquaculture brings, there are still specific critical points that need attention. One of such points is a potential risk for public health if the RAS system is not maintained properly.
Biological filtration, that is used to remove harmful pollutants, can be associated with biofilm formation that can grow on all the components in the RAS system. As the water is being reused and recirculated, parts of the pathogens could add to the formation of biofilm, and as a result, lead to the exposure of the healthy fish to it.
Ozone is effective in eliminating pathogens and improve water quality, which inevitably leads to the improvement of the overall system.
Ozone has shown to be very efficient in the improvement of taste and odour to control and prevent the incidents of off flavours. Using ozone in the RAS systems had demonstrated to be potent in reducing geosmin (earthy flavour of the fish) concentration in the water.
Ozone gas is a very potent yet natural oxidizer that is widely used in aquaculture application around the world. It is an effective method to achieve both disinfection and improve water quality in the whole system.
The application for ozone in aquaculture includes but is not limited to:
- Inactivation of fish pathogens
- Oxidation of organic matter, including colour and nitrates
- Supplementing the existing water treatment process
Applying ozone in your RAS system has a number of benefits and advantages and in order to enjoy all of these, it is essential to determine the correct dosage of ozone and select the right system design.
