Since the 1980s, UVc rays have been used for industrial water disinfection purposes for obvious reasons: with a wavelength of 254 nm, type-C ultraviolet is capable of inactivating and destroying the micro-organisms (bacteria, viruses, moulds) present in the fluids, without using chemical products . At UVRER , we have specialized in ultraviolet water disinfection since 1982 .
Sars-CoV-2 is a weak germ ; a single UVc dose of approximately 3 mj/cm2 is sufficient for effective destruction*. In addition, our systems deliver UVc doses of 40 mj/cm2 , which guarantees optimal disinfection of fluids , including for water purification (which requires irreproachable quality).
The only additional criterion to take into account is the transmission (clarity) of the water to be treated. In fact, depending on its quality, the disinfection capacity of UVc light varies . To remedy this, it is necessary to carry out a pre-filtering, to control the thickness of the layer of water in the system and to adapt the disinfection power.
Since 1982, our expertise has enabled us to determine and design the most appropriate equipment to meet your specific problem: we are therefore able to provide you with the system you need.
UV-C lamps are particularly effective in destroying the DNA of viruses, bacteria and other microorganisms. Hundreds of laboratory studies have proven this. Research against covid-19 (SARS Cov-2) very quickly proved the effectiveness of UV-C in this fight.
Historically, for want of anything better, the technology used was that of tube lamps. The ionized gas in the tube scatters precise radiation with a wavelength of 254 nm. This provides good general efficiency.
Thanks to AQUISENSE, the UV-C LED has become the breakthrough technology. As a world leader, both technological and commercial, their range is very wide: https://www.lampe-uv-led.fr/pages/nos-produits/nos-produits.html
…and has the following main advantages:
Compact Low energy consumption No water heating Shock resistant Unequaled longevity
Before any acquisition, the important points are as follows:
What is the throughput of your installation? What is the available space? Install a pre-filter before the UV-C lamp, to keep it clean. Indeed, UV-C lamps are like lighting lamps: only those that are clean light well.
"Sustainable development" spirit:
Avoid chemicals and disinfectants of all kinds. It's better for you AND the environment. Prefer an LED lamp which cuts off when the flow is zero. For all intermittent uses, you'll get huge electricity savings and a much better longevity of your investment. For the equipment of a variable flow rate installation (house), prefer a controlled lamp whose radiation intensity will be indexed to the water flow rate.
It is with pleasure that we will answer any new questions that you will ask us.
