UV disinfection for freshwater

Freshwater differs from seawater because of the small amount of dissolved salts it contains. It comes from rivers, lakes, groundwater or glaciers. Compared to the sea water, the transmittance is generally higher, usually 90 to 95%. 1H2O3 has selected a range of specific UV disinfection reactors applied to all freshwater systems
Private swimming pools and spas, aquariums and freshwater ornamental ponds, aquaponics / aquaculture / freshwater fish farming. The disinfection of water using these UV reactors ensures that the water is free of micro-organisms and can be easily adapted to existing installations.

UV technology is better at doing this 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

Sterilization of fresh water using stainless steel UV reactors mainly prevents the development of bacteria by ensuring :

  • Crystal clear water of ideal quality, without the taste of chlorine!
  • 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, freshwater UV disinfection systems do not generate harmful disinfection by-products 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 …).

Advantages of UV disinfection for fresh water

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

  • Reactors adapted in mirror-polished 316L stainless steel with optimized performances with UV-C lamps from the latest technologies with High Intensity (HO) performances
  • Long life of the UV water treatment lamps (13,000 hours depending on the number of times they are switched on)
  • Aquatic life protection; UV sterilizers do not present any danger to fish, corals or invertebrates
  • Dedicated electronic ballasts for maximum UV lamp efficiency 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 avoids the propagation of diseases in the water, leaving no opportunity for pathogenic micro-organisms to reproduce.

For those who need an efficient disinfection system for fresh water, the complete range of UV reactors dedicated to this application can be consulted online, and the design can be done on this page.

Design tips: UV disinfection for fresh water

On the UV reactors for fresh water page, many solutions are proposed (up to a unit flow rate of 130 m3/h). For higher flow rates, up to 130 m3/h, please contact us!

  • Select “Freshwater”.
  • Select the water source to be potabilized, e.g. “Aquaponics / Aquaculture / Freshwater fish 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, we will send you the design right away

In any case, to ensure optimal disinfection and to determine whether prefilters are necessary, it is recommended that a source water analysis be performed with these parameters:

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