UV disinfection system applied to the sterilizer for seawater intake

For the seawater intake, the sizing of the sterilizer depends on the following main parameters:

  • The flow rate of water to be treated
  • The right dose of ultraviolet light
  • Water quality

The equipment to be used, particularly the HDPE sterilization chamber, must be adapted to this application.

If you want to equip yourself with an effective sterilizer disinfection system for seawater intake, 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 of water is also part of an environmental approach:

  • In terms of health, the water treatment, without the addition of harmful pool products, guarantees swimming without the risk of allergies and respiratory diseases (non-chemical)
  • It is also of interest in terms of comfort by ensuring clear, crystal clear and odorless water.
  • The absence of chlorine makes for a safe, environmentally-friendly process.
  • UV treatment makes it possible to achieve real savings thanks to a long service life of the installations and simple, reliable, and long-lasting equipment.
  • Last but not least, the system can be installed and maintained quickly and easily.

  • Select ” “
  • Select the source of water to be made drinkable, for example “Salt pools”.
  • 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, we will 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 install a UV sterilizer as soon as seawater is inlet?

Installing a UV sterilizer at the inlet of the seawater intake effectively eliminates pathogenic microorganisms such as bacteria, viruses and algae. This ensures optimal water quality for applications in aquaculture, fish farming or purification systems, reducing the risk of disease and contamination.

Due to the corrosive nature of seawater, it is essential to use tough materials such as high-density polyethylene (HDPE) or 316L stainless steel. These materials ensure the durability and effectiveness of the UV disinfection system in demanding marine environments.

Turbidity, or the clarity of the water, influences the transmission of UV rays. Cloudier water reduces UV penetration, thus decreasing the effectiveness of disinfection. It is therefore crucial to pre-treat the water to reduce turbidity before UV disinfection, thus ensuring optimal inactivation of microorganisms.

UV disinfection offers several advantages:

  • Chemical-free : It does not introduce chemicals into the water, preventing the formation of potentially harmful by-products.

  • Fast effectiveness : it neutralizes microorganisms 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 the marine environment.

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.
