UV Disinfection

Without any addition of active substance, nor creation of by-product, the UV-C light inactivates the microorganisms present in the water (bacteria, phytoplankton, zooplankton).


  •  Titanium reactor equipped with a single polychromatic, medium pressure, high intensity UV lamp,
  • A high-quality quartz sleeve protecting the UV lamp,
  • Optimized design by CFD (Computational Fluid Dynamic), taking into account the seawater quality (UV transmittance) and fluid speeds on the quartz sleeves, in order to facilitate cleaning and maintenance,
  • Lamp driven by electronic transformer allowing precise management of the UV lamp in order to optimize its regulation, reduce the power consumption and prolong its life,
  • Monitoring through UV sensor (intensity),
  • Modular design, facilitating the installation of UV reactors in parallel and a better adjustment to the flow that has to be treated.


The sun emits invisible light: ultraviolet light. This natural phenomenon is reproduced inside the reactors in the BIO-UV Group’s product ranges using powerful lamps, the result of leading-edge technology, that emit UV-C rays.

At 254 nanometers, the optimum wavelength for destroying micro-organisms (viruses, bacteria, algae, yeasts, mould...including Legionella and Cryptosporidium), UV-C rays penetrate the heart of DNA and disturb the metabolism of cells until they are totally destroyed. All germs are thus desactivated and cannot reproduce.

That is why BIO-UV has designed ranges of UV reactors suitable for commercial pools and spas in order to reduce or eradicate these side effects.


The reactors in the BIO-UV ranges are dimensioned according to the pump flow rate, as it is the combination of the contact time in the reactor and the power of the lamp(s) that will ensure that the necessary dose (expressed in millijoules per square centimeter or mJ/cm2) sufficient to kill 99.9% of the micro-organisms (bacteria, viruses, algae in suspension,…) is received.
