The application of ozone in aquaculture mainly focuses on improving water quality, preventing diseases and controlling microbial contamination. The following are specific applications of ozone in aquaculture:
Water purification:
Ozone can oxidize and decompose organic matter in the water, such as residual bait, feces and dead plant cells, thereby reducing the turbidity and organic load in the water, and improving the transparency and overall water quality of the water body.
Sterilization and disinfection:
Ozone has a strong oxidizing ability, which can kill bacteria and viruses in the water, reduce the occurrence and spread of diseases, and protect the health of aquatic animals such as fish and shrimps.
Control algae and pathogens:
Ozone can inhibit the reproduction of harmful algae such as blue-green algae, while controlling the number of pathogens and maintaining the ecological balance of the water body.
Removing odors:
Ozone can remove odors from water, such as harmful gases such as hydrogen sulfide and ammonia, creating a more suitable environment for the growth of aquatic animals.
Control nitrite concentration: Ozone can quickly reduce nitrite concentration and maintain aquatic ecological balance.
When using ozone for aquaculture, you need to pay attention to the following three points:
The concentration of ozone needs to be precisely controlled to ensure effective sterilization without harming aquatic animals.
Water quality parameters such as pH, dissolved oxygen and ozone residuals should be monitored regularly to adjust the amount of ozone used.Different breeding methods have different ozone dosing methods.
Chlorine is the most commonly used disinfectant and oxidizer in all hatcheries. The main disadvantages of using chlorine are:
1. Dangerous disinfectant by-products, the final reaction after organic oxidation.
2. Residual chlorine residue.
3. The time for natural degradation of residual chlorine is unpredictable.
Ozone replaces chlorine disinfectant, and the disinfection effect of ozone is stronger than chlorine。
Advantages of Ozonation :
1. Ozone is very quick in disinfection
2. Ozone is a very strong oxidant on organics
3. Disinfectant by-product are negligible
4. Residual ozone naturally degrades to Oxygen
5. Effective & instant destruction of unused residual ozone
