Aquaculture
Ozone in recirculating aquaculture systems
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 it to the healthy fish.
Improves water quality
Ozone is effective in eliminating pathogens and improving 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 have demonstrated to be potent in reducing geosmin (earthy flavour of the fish) concentration in the water.
