UV Systems for Aquaculture/Fish Hatcheries

Application of UV disinfection system in aquaculture

Process flow

The UV system is integrated into the key nodes of the water cycle in fish hatcheries as a terminal treatment unit:

Post-treatment section

Located after sand filtration/biological filtration, the last barrier before the treated water enters the breeding area

Circulating water system (RAS)

Continuous inactivation of pathogens in a closed circulation pipeline

Nursery and cultivation area

Targeted prevention and control of fungal infection of fish eggs (Saprolegniasis, etc.)

Technical principle

Use 253.7nm UV spectrum to penetrate the cell wall of microorganisms

Achieve at irradiation intensity of 30,000-50,000μW/cm²:

✔ Bacteria (Vibrio, etc.) inactivation rate ≥99.99%

✔ Viruses (IPNV, etc.) inactivation rate ≥99.9%

✔ Inactivation of parasite (dinoflagellates, etc.) spores

Industry challenges

Water crisis

Eutrophication of water bodies in aquaculture areas increased by 12% annually

Pathogen concentration at water intake points exceeded industrial standards by 3-8 times

Production pressure

Aquaculture density increased by 40-60% in the same area

Fish fry survival rate fluctuates by up to ±25%

Traditional limitations

Chemical agents cause drug residues in fish

Ozone system produces toxic bromate byproducts

FupengWater solution

Industrial-grade UV disinfection system features

Closed reactor

316L stainless steel chamber (IP69K protection level), suitable for DN50-DN500 pipelines

Intelligent control system

Real-time monitoring of UV intensity + Automatic quartz sleeve cleaning mechanism

Energy efficiency optimization design

Save 35% of electricity compared with traditional systems (energy consumption per ton of water treatment ≤ 0.8kW·h)

Core value

Improved biosafety

Fish fry survival rate increased by 18-22%

Eliminate the risk of cross-contamination of chemical agents

Production efficiency

System maintenance cycle extended to 12 months

Equipment floor space reduced by 40% (vertical modular design)

Water quality assurance

Water meets SC/T 9101-2007 aquaculture water quality standards

Ultraviolet transmittance (UVT) attenuation rate <5%/year
