Benefits of Chlorine Dioxide in Aquaculture
1. Chlorine dioxide is easily soluble in water, and its disinfection effect is not affected by the pH of water quality.
2. Chlorine dioxide can effectively kill bacteria, viruses, fungi, bacterial spores and bacteriophages in water. In water, due to the adsorption between the active ingredient molecules of chlorine dioxide and the capsid protein of the virus, high concentrations of disinfection molecules are gathered on the surface of the virus particles, thus enhancing its killing effect.
3. The bactericidal ability of chlorine dioxide is stronger than that of chlorine, the bactericidal effect is faster than that of chlorine, the bactericidal effect is more than 10 times that of chlorine, and the duration of the remaining dose is also longer.
4, 0.3-3 mg/L concentration of chlorine dioxide preparation can make the total number of bacteria in aquaculture water decreased by more than 92%, and can increase the dissolved oxygen in aquaculture water, the effect on inorganic nitrogen salt is not obvious, 0.3 mg/L chlorine dioxide preparation has no obvious effect on phytoplankton; 1.2 mg/L below the water zooplankton Daphnia is not obvious. 3 mg/L can inhibit the reproduction and growth of phytoplankton; more than 2.4 mg/L concentration can affect the reproduction and survival of zooplankton Daphnia. Chlorine dioxide preparations are also superior to other chlorine-containing disinfectants in terms of their impact on water quality.
The role of chlorine dioxide in aquaculture
1. Chlorine dioxide is a broad-spectrum disinfectant, which has a high killing effect on pathogenic microorganisms in water, including viruses, spores, heterotrophic bacteria, sulfate, reducing bacteria and fungi in water distribution network.
2. Chlorine dioxide can kill Escherichia coli in a wide range of pH value. Its killing effect is related to temperature and is a function of temperature (1/T). This advantage makes up for the decrease of solubility of chlorine dioxide in water due to the increase of temperature. Chlorine dioxide diffuses faster in water than chlorine, so it is more effective than chlorine at low concentrations.
3. Chlorine dioxide is more effective in killing viruses than ozone (O3) and chlorine. During the flood, chlorine dioxide has a good killing effect on many viruses, such as coxsackie (intestinal) bacteria, human intestinal virus, herpes virus, new town virus, phage, vaccinia virus, polio virus and so on.
4, chlorine dioxide on the water treatment system in the precipitation, clarification, filtration equipment and water distribution network of algae heterotrophic bacteria, iron bacteria, sulfate and reducing bacteria, etc., have a good removal and killing effect, adding chlorine dioxide will be conducive to the operation and maintenance of water treatment facilities.

To sum up the relevant information about aquaculture disinfection, it can be seen that the high-efficiency and broad-spectrum disinfection method of chlorine dioxide is completely suitable for aquaculture. It not only does not have some common problems of other disinfectants, but also can ensure its own disinfection performance. It not only has high-efficiency sterilization and disease prevention effects on fish, shrimp, crab, turtle and frog aquatic organisms, but also ensures the safety of water quality, while forming a perfect protection for water quality and water bodies, it further ensures the safety of aquatic products, including human and natural environment.
