In the aquaculture industry. Due to disease control and water quality management have always been the key to the success or failure of aquaculture. At the same time with the increasingly strict requirements of food safety and environmental protection. The limitations of traditional fishery drugs and disinfectants have become increasingly prominent. In this context, hypochlorous acid generators, as a solution for intelligent. On-site preparation of highly efficient disinfectants. Are gradually becoming the standard configuration of modern aquaculture.
Comparison of hypochlorous acid generator and traditional disinfectant
Traditional disinfection methods usually involve the purchase. Storage and transportation of high concentration of corrosive disinfectants (such as sodium hypochlorite or bleaching powder), which is not only costly. But also easy to volatilize the effective ingredients due to light and heat.
Due to hypochlorous acid generator through electrolysis technology. Salt and water as raw materials. Therefore in the equipment inside the instant generation of stable concentration of hypochlorous acid solution. The core principle is as follows:
Hypochlorous acid is recognized by the scientific community as the “core weapon” in the disinfection of chlorine preparations. Unlike conventional sodium hypochlorite (the main component of 84 disinfectant), hypochlorite has small molecules, no charge, and can easily penetrate the cell wall of pathogens. Its bactericidal efficiency is more than 80 times that of the hypochlorite ion (ClO⁻)
Application advantages of hypochlorous acid generator in aquaculture
Compared with traditional bleaching powder. Povidone iodine or chlorine dioxide, the disinfectant prepared on site by hypochlorous acid generator has the following incomparable advantages:
Hypochlorous acid green environmental protection, no stress response to fish and shrimp
Traditional chlorine preparation is often irritating and easy to damage the gill tissue of fish and shrimp. Resulting in slime loss and even death. Although hypochlorous acid oxidation is strong, but its nature is very unstable. And the reaction with organic matter will quickly reduce to water. Non-toxic no residue. The experimental data showed that the irritation of hypochlorous acid to fish and shrimp was much lower than that of traditional medicine under the effective bactericidal concentration as long as it was used properly.
Hypochlorous acid broad spectrum efficient: instant killing pathogenic bacteria
Hypochlorous acid can kill more than 99.9% of Vibrio bacteria. Aeromonas hydrophila, and various fungi and viruses in a very short time (usually within 30 seconds). This is essential to control diseases with high mortality at the seedling stage.
Hypochlorous acid purify water, reduce ammonia nitrogen and nitrite
Hypochlorous acid is not only a disinfectant. But also an excellent water quality improver. It has strong oxidation, can oxidize part of the organic pollutants in the water body, decompose ammonia nitrogen and nitrite. Play a role in purifying water quality. Increase oxygen, and create a more comfortable living environment for aquatic animals.
For which scenarios hypochlorous acid generators can be used in aquaculture
Hypochlorous acid generator because of its adjustable concentration (usually can be accurately controlled in the range of 10-500 PPM), almost throughout the whole process of aquaculture:
Scenario 1: Seedling period (the most critical protection)
Seedling pools have high water quality requirements. The use of low concentration hypochlorous acid water (such as 0.5-1.0mg/L) for whole pool sprinkling or pipeline flow treatment can effectively inhibit the opportunistic pathogenic bacteria in the water without harming the seedlings, and significantly improve the survival rate of seedlings.
Scenario II: Water disinfection during adult fish culture
In the high temperature season or the high incidence period of disease. The high concentration stock solution was prepare by the generator. And the whole pool was sprinkled after dilution. Used to prevent bacterial septicemia, rotten gill disease, enteritis and other common diseases.
Scenario 3: Tool and field elimination
The net, transport vehicle, feed table and cement pool wall are sterilize by high-pressure spraying. Because it is non-corrosive (at recommended concentrations) and has no residue, there is no need for tedious neutralization cleaning as with potassium permanganate or bleach.
The current hypochlorous acid generator has entered the intelligent era. New generation devices such as ShootHOCL are equip with adaptive feedback algorithms.
>The equipment can dynamically sense the changes of water temperature, raw material concentration and environment, and automatically compensate the electrolytic parameters to ensure that the effective chlorine concentration of the output is always accurately controllable regardless of spring, summer, autumn and winter, south and north. At the same time, many equipment has integrated PLC control system and industrial control touch screen, the operator only needs one key to start, the equipment automatically complete the salt, electrolysis, production, cleaning the whole process, truly realize the “fool” operation
