Ozone Benifits :
Ozone (O3) is a very effective disinfection agent and can be used in aquaculture/ fish farming to replace chlorine and bromine containing disinfection chemicals.
The advantage of the use of ozone compared to the other water treatment agents is the fact that the water environment will increase dramatically. The use of ozone prevents the formation of chlorine or bromine containing byproducts, like chloramines and trihalomethanes. Ozone will even breakdown already formed unwanted chlorinated byproducts.
Ozone Aquaculture Applications :
Fish farming involves culturing of fish commercially in tanks or enclosures, usually for food. Fish hatcheries and fish farms play an ever increasing role in supplying the world’s demand for fish. To effectively supply this demand, fish farms must practice intensive farming techniques where more and more fish are farmed in the same or smaller tank volumes. Of couurse, as the fish density grows so does the risk of infection by water-borne bacteria and viruses.
Because of these problems, some aquaculture operators frequently use strong antibiotic drugs to keep the fish alive (but many fish still die prematurely at rate of up to 30 percent). In some cases, these drugs have entered the environment. Additionally, the residual presence of these operations still use antibiotics, many of which considered to be serious problem to human health as well as for fish farming.
Ozone is the ideal disinfectant for aquaculture because of its ability to kill bacteria and viruses without leaving any residue. Ozone is an effective treatment that:
• Oxidizes organic matter such as fish excrement
• Precipitates dissolved matter
• Allows the micro-flocculation of organic matter
• Destabilizes colloidal particles
• Disinfects the water
Use of Ozone in Aquaculture :
• Removal of fine and colloidal solids
• Removal of dissolved organic compounds
• Removal of Nitrite
