Our job

The ultraviolet water treatment specialist

On its production site in Lunel (Herault), the BIO-UV Group designs, manufactures and markets ultraviolet (UV-C) disinfection systems and concepts adapted to a large number of applications, such as :


Since 2011, the group offers complete system of boat ballast water treatment BIO-SEA® which combines mechanical filtration and UV disinfection, without any chemical treatment whatsoever.

The BIO-SEA® products are IMO type approved, USCG AMS accepted and USCG type approval currently in process.

Having obtained, since 2013, Type Approval (International Disinfection certification awarded by Bureau Veritas under the control of the French government, and the International Maritime Organization - IMO) BIO-SEA® is now marketed throughout the world.

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.

The use of type C ultraviolet rays as a means of sanitisation has been known for more than a century. They have been used in various applications such as for drinking water purification, aquaculture, fish farming, as well as in hospitals and the pharmaceutical industry. After filtration, water circulates through the UV sanitiser for complete disinfection - bacteria, viruses and algae are completely deactivated without side effects or dangerous by-products. This process results in pure and clear water.

Your need for chemical products is reduced. You will still need to maintain a small residual of chemicals in your pool in order to destroy any micro-organisms that do not find their way into the UV sanitiser.
Health : a pleasant and risk-free swimming experience
  • No risk of allergy or respiratory diseases due to chlorine (asthma etc.). The water quality guarantees a healthy bathing experience.
  • No harmful swimming pools products

The ultra-violet rays emitted by the device don’t represent any danger to health !


Comfort : safe, crystalline and no water smell

  • Gone are irritated eyes and mucous membranes, dry skin and damaged hair. The water purification guarantees an unequalled bathing comfort
  • No unpleasant smell in the water or in the air
  • No chlorine or salt: prevents corrosion and chlorine derivatives
  • Neutralise the micro-organisms that are not affected by chlorine and salt


Sustainable development : an environmentally friendly process

  • Healthy process, widely used for the natural ponds disinfection
  • Chlorine-free and salt-free
  • Drastically reduce chemical use
  • Non-polluting waste water


Savings : a reliable system

  • Reliable and user-friendly materials: no electronic involved
  • Long life cycle of the UV lamp (13 000 hours: 3 years for a seasonal pool for example)
  • Non-corrosive treatment
  • No discolouration, the installations life cycle is extended
  • Gone are over-consumption of chemicals to compensate an overdose
  • Lamp replacement every 3 years


For a guaranteed peace of mind

  • Easy and fast installation and maintenance. The BIO-UV treatment for pools and spas doesn’t require specific works and it adapts to the water filter system.
  • Compatible with all types of coatings, materials etc. Each UV basin, which is existing or under construction, has an adapted UV disinfection system.
  • Continuous disinfection
  • 5-year guarantee for the INOX reactor
