Hypochlorous acid generator is used for freshwater fish farming.

Due to hypochlorous acid generator is a kind of equipment that produces hypochlorous acid disinfectant on site by electrolyzing dilute salt solution (salt water). Unlike the traditional use of finished chlorinated disinfectants. The device only needs salt, water and electricity to generate efficient and safe disinfection solutions on demand.

Its working principle is base on electrolysis technology: when diluted brine is passed through an electrolyzer with an electric current. Sodium chloride (NaCl) and water (H₂O) undergo an electrochemical reaction to produce a mixed oxidant solution with hypochlorous acid (HClO) as the main component. This on-site preparation ensures the freshness and efficiency of the disinfectant.

1. Higher bactericidal efficiency: Due to the bactericidal ability of hypochlorous acid is 80 to 100 times that of hypochlorite. therefor It is easier to penetrate the microbial cell membrane and destroy its internal structure. And has excellent effects on bacteria, viruses and fungi.
2. Stronger safety: Hypochlorous acid in the effective concentration of human and fish toxicity is very low. No pungent odor, will not produce harmful chloramines. Which is more friendly to aquaculture personnel and fish health.
3. Environmentally friendly: hypochlorous acid decomposition products for water and trace chloride, no residual toxicity. Will not cause long-term pollution of water.

Common pathogenic microorganisms in aquaculture water. Such as Aeromonas (causing bacterial sepsis) and Flavobacterium cylindricum (causing columnar disease). Are highly sensitive to hypochlorous acid. Studies have shown that a concentration of 0.5-1.0 mg/L hypochlorous acid can kill 99.9% of common aquatic pathogens within 30 minutes. And it is safe for most cultured fish at this concentration.

Breeding tools, net tools, feed containers, etc. often become the vector of pathogen transmission. The use of hypochlorous acid solution immersion or spray disinfection. Can effectively cut off the transmission route. Compared with traditional disinfectants such as formaldehyde and potassium permanganate. Hypochlorous acid is non-corrosive. More friendly to equipment. And does not need to wash residues for a long time.

In the recirculating aquaculture system. Biofilm is easily forme on the pipes and biofilters, which may become the “shelter” of pathogenic bacteria. Regular use of hypochlorous acid treatment can effectively control biofilm overgrowth without affecting the main function of beneficial bacteria such as nitrifying bacteria.

The practice data of a carp farm in Guangdong province showed that after the introduction of hypochlorous acid generator:

• Reduce disinfection costs by about 40% (from about 3,500 yuan per month for chemicals to 2,100 yuan, and about 500 yuan for electricity and salt)
• Fish incidence drop by 60 percent and antibiotic use was reduce by 75 percent
• Disinfection operation time is reduce by 70%, and labor costs are significantly reduce
• The water quality index is more stable, and the growth rate of fish is increase by 12%

In addition to the economic benefits, the environmental benefits are also significant. The use of traditional chlorine preparation may lead to excessive chlorine residue in water and affect the quality of discharged water. The natural decomposition of hypochlorous acid makes its environmental footprint smaller, which is in line with the development direction of green aquaculture.

Intelligent integration: hypochlorous acid generator and water quality monitoring system linkage, automatic disinfection on demand

• Modular design: adapt to the needs of different scale farms, from family farming to industrial production
• Multi-technology integration: Combined with ultraviolet, ozone and other disinfection technologies to form a multi-level disinfection strategy
• Standard system establishment: THE establishment of industry use norms and safety standards, promote the standardized application of technology
• Concentration adjustable: The concentration can be adjust according to the scene
• PH stability: the equipment can accurately adjust the concentration according to the site water quality.

1. Concentration control: Different application scenarios require different concentrations. General water disinfection use 0.3-0.8 mg/L, equipment disinfection use 10-50 mg/L, epidemic emergency treatment can be short-term use 1-2 mg/L. It should be adjust according to the specific water quality (pH value, organic matter content, etc.).
2. pH management: The bactericidal effect of hypochlorous acid is greatly affect by pH value. In the range of pH 6.0-7.5, hypochlorous acid accounted for the highest proportion, and the disinfection effect was the best. Aquaculture water is usually in this range, so no special adjustment is necessary.
3. Safety test: Before large-scale use, small-scale testing should be carried out to observe the fish reaction. Avoid disinfection under stress conditions such as high temperature and low dissolved oxygen.
4. System compatibility: When used in a recirculating aquaculture system, it is necessary to pay attention to the impact on the biological filter. It is recommended to temporarily bypass the biofilter during disinfection or choose to do it during system water exchange.
