UV disinfection for fresh water

Fresh water differs from seawater because of the small amount of dissolved salts it contains. It comes from rivers, lakes, groundwater or glaciers. Compared to seawater, the transmittance is usually higher, usually 90-95%. 1H2O3 has selected a range of specific UV disinfection reactors applied to all freshwater systems
: private swimming pools and spas, freshwater aquariums and ornamental pools, aquaponics / aquaculture / freshwater fish farming. The disinfection of water by means of these UV reactors thus makes it possible to guarantee water free of microorganisms, easily adapting to existing installations.

UV does this better than any other technology on the market. Pathogen reduction relies on the power of ultraviolet light to destroy microorganisms and toxic by-products.

UV disinfection system for fresh water

The sterilization of fresh water by means of stainless steel UV reactors mainly prevents the development of bacteria by ensuring:

  • Crystal clear water of ideal quality, and without chlorine taste!
  • The development of the fauna and flora and an absolute respect of the environment
  • Quick and easy to install
  • Easier maintenance thanks to a more user-friendly structure.
  • Free and easy online design

In addition, UV disinfection systems for fresh water do not generate harmful by-products of disinfection and operate autonomously. The size of the reactor will be calculated to ensure the necessary and sufficient dose for the elimination of 99.9% of microorganisms (bacteria, viruses …).

Benefits of UV Disinfection for Freshwater

The UV treatment of 1H2O3 for fresh water disinfection has many advantages:

  • Adapted reactors in 316L mirror-polished stainless steel with optimized performance with UV-C lamps from the latest technologies with High Intensity (HO) performance
  • Very long life of UV water treatment lamps (13,000 hours depending on number of ignitions)
  • Protection of aquatic life; UV sterilizers do not pose any danger to fish, corals or invertebrates
  • Dedicated electronic ballasts ensuring maximum UV output of the lamps and integrated control
  • Single lamp and sealing system for easy maintenance. Lamp operation control by individual indicator lights
  • Reduced pressure losses
  • Inlet/outlet connection with supplied union fittings
  • Drain plug
  • Fixing brackets
  • Maintenance: quick and easy lamp change and quartz sleeve cleaning

Finally, UV disinfection of fresh water prevents the proliferation of diseases in the water, leaving no possibility for pathogenic microorganisms to reproduce.

  • Suspended solids (TSS)
  • Transmittance UV

FAQ

Why choose UV disinfection for fresh water?

UV disinfection is an effective method to eliminate up to 99.99% of pathogenic microorganisms present in freshwater, such as bacteria, viruses and protozoa. It does not use any chemicals, preserving the natural taste and smell of the water, while preventing the formation of harmful by-products.

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 ensure the health safety of fresh water.

UV disinfection is highly effective against a wide range of microorganisms, including bacteria, viruses, and protozoa. However, its effectiveness may be reduced if the water is cloudy or contains suspended particles, as these can protect microorganisms from exposure to UV rays. It is therefore recommended to use pre-filtration to improve the clarity of the water before UV treatment.

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 perfectly suitable for home use. It is used to treat well water, reclaimed rainwater, or even water from the public network, providing additional protection against pathogenic microorganisms. Many UV systems are designed for easy installation in homes, ensuring quality drinking water for the whole family.
