UV disinfection system applied to oyster and shellfish farming

The UV disinfection system oyster and shellfish farming is a marine aquaculture crop. The reactors used thus make it possible to sterilize the water and obtain a better quality. This is particularly true for bacteriological parameters.

The crops pass through purification tanks before being packaged to provide the highest quality.

UV lamps can eliminate 100% of the bacterial load in the breeding environment and solve bacteriological problems. In addition, UV treatment is more effective than other sterilization techniques because:

  • easy to use
  • reliable
  • low investment cost

If you want to equip yourself with an effective disinfection system for shellfish farming, the complete range of UV reactors for salt water can be consulted online, and the sizing can be done on this page.

Disinfection system benefits

In addition to guaranteeing healthy water free of any risk of contamination by microorganisms, UV treatment is also part of an environmental approach:

  • In terms of health, the treatment of the water, without the addition of harmful pool products, guarantees swimming without the risk of allergies and respiratory diseases
  • It is also of interest in terms of comfort by ensuring clear, crystal clear and odorless water
  • The absence of chlorine guarantees an environmentally friendly and healthy process
  • UV treatment makes it possible to make real savings thanks to a long service life of the installations and simple, reliable, and long-lasting equipment
  • Last but not least, the system is quick and easy to install and maintain.

Sizing advice: UV disinfection applied to oyster and shellfish farming

On the page dedicated to UV reactors for corrosive/salt water, many solutions are offered (up to a unit flow rate of 130 m3/h). If your flow rate exceeds 130 m3/h, please ask us!

  • Select ” “
  • Select the source of water to be drinkable, for example “Oyster farming, shellfish farming”.
  • Enter the flow rate to be treated (for example 25 m3/h)
  • Adjust the cost of electricity in your country (for example 0.09€ for France; 0.23€ for Germany)
  • Let 30 mJ / cm² (or adapt)
  • Specify the temperature of the water (normally, between 5 and 40°C is sufficient)
  • Please enter your email address so that we can send you the design right away.

In any case, to ensure optimal disinfection and decide if pre-filters are necessary, it is recommended to carry out an analysis of the water source with these parameters:

  • Iron
  • Hardness
  • Turbidity
  • Manganese
  • Suspended solids (TSS)
  • Transmittance UV

FAQ

Why is UV disinfection essential in oyster and shellfish farming?

UV disinfection is crucial to remove pathogenic microorganisms from seawater used for shellfish farming and purification. It significantly reduces the bacterial load, in particular bacteria of the genus Vibrio, which are responsible for diseases in shellfish and potentially dangerous for human consumption. By ensuring quality water, UV disinfection contributes to the health of farms and the health compliance of finished products.

A UV disinfection system for oyster farming is designed to treat large volumes of seawater. It is usually composed of corrosion-resistant UV reactors, often made of materials such as HDPE or PVC, suitable for the saline environment. Seawater is exposed to lamps that emit UV-C rays, which destroy the DNA of microorganisms, rendering them harmless. These systems are effective in treating the water used in the purification tanks before shellfish are marketed.

UV disinfection has several advantages:

  • Chemical-free : it does not alter the taste or smell of shellfish.

  • Fast effectiveness : it neutralizes pathogens in a few seconds.

  • Respect for the environment : no chemical residues are released into the natural environment.

  • Ease of use : UV systems are easy to integrate and maintain.

These advantages make UV disinfection a preferred solution to guarantee health safety in oyster farming.

Regular maintenance is essential to ensure the effectiveness of a UV system:

  • Cleaning of quartz sheaths : The accumulation of deposits can reduce UV transmission.

  • Replacement of UV lamps : Lamps should be changed according to the manufacturer’s recommendations, usually after 8,000 to 10,000 hours of use.

  • Component Verification : Ensure the integrity of seals and corrosion-resistant materials.

Proper maintenance ensures optimal disinfection and extends the life of the system.

Yes, UV disinfection is recognized as an effective method to ensure the sanitary quality of shellfish. It is often used in purification tanks to reduce the bacterial load before being released to the market. By adhering to design and usage standards, UV systems help meet regulatory requirements for food safety.
