Unlike the other techniques used for water treatment (softeners, reverse osmosis, water purifiers, filter carafes or filter cartridge holders), UV sterilisation is a process that provides effective water disinfection.

25 watt UV steriliser

To make water drinkable, this appliance can treat 4.8 GPM or 21.8 litres/minute, i.e. 1.30 m³/hour.
To make water clean, this appliance can treat 6 GPM or 27 litres/minute, i.e. 1.63 m³/hour.

It consists of:

  • a 304 stainless steel tube
  • a quartz (silicon glass tube)
  • 2 silicone seals
  • a 220v ballast;
  • a UV lamp (life of approximately 8,000 hours)


  • length of ballast wire 1.95 metres
  • external diameter of stainless steel tube 64mm
  • stainless steel tube length 520mm

Quartz (also known as silica) is made of silicon glass, a high-quality type of glass composed almost exclusively of pure silica.

How does UV sterilisation work?

In order to neutralise bacteria, microbes, viruses, unicellular algae and other living cells in the water, the water is passed through a treatment chamber where it is irradiated with ultraviolet rays.

Depending on the amount of energy received (measured in micro-Ws/cm2), the micro-organisms will be:

  • Sterilised by a bacteriostatic effect (they continue to live but can no longer reproduce).
  • Destroyed (bactericidal effect).

Be careful, however, to use the right frequency of ultraviolet electromagnetic wave.
Not all UV rays have a sterilising or disinfecting effect:

  • UVc: ozone formation around 185 nm
  • UVc: destruction of micro-organisms between 200 and 280 nm
  • UVb: vitaminisation of food products between 285 and 315 nm
  • UVa: skin pigmentation between 315 and 400 nm

stérilisation UV


To sterilise the water you need a frequency of around 254nm inside the treatment chamber.
This is the shape of the WC that should be used.

UV sterilisation eliminates pathogenic micro-organisms, but this does not always mean that the water is pleasant to drink or use. That's why this process is sometimes combined with a filtration method to improve the taste of the water.

Although UV sterilisation eliminates pathogenic micro-organisms, it has no effect on the taste or turbidity of the water, so it needs to be combined with a filtration method to make it more pleasant to drink and use.


Why choose this technique?


UV sterilisation offers a number of advantages:

  • does not use chemical products
  • no chemical or physical modification of the treated water
  • compact system that takes up little space and is relatively easy to install
  • easy maintenance: simply change the UV lamp about once a year
  • instant bactericidal effect

It is ideal for:

  • sterilise water from local sources (spring, rain, river, well, borehole, etc.)
  • maintain your pool using fewer chemicals
  • a professional who discharges water and wishes to limit its environmental impact

  • Stainless steel chamber 515 millimetres external length x 65 millimetres external diameter
  • Water pipe connections for 3/4" (20/27) connections
  • Bracket height 87 mm, width 90 mm and depth 15 mm
