Purification de l'eau par ultraviolets

Les systèmes de filtration d'eau par UV portent la purification de l'eau à un niveau supérieur.

Il est essentiel de fournir une solution sûre pour lutter contre les micro-organismes résistants au chlore, tels que Giardia et Cryptosporidium, ainsi que contre de nombreux autres virus et bactéries présents dans votre eau. Les filtres classiques peuvent être efficaces pour éliminer le sable, les métaux et autres sédiments de grande taille, et peuvent également améliorer le goût de votre eau, mais ils ne peuvent pas détruire les micro-organismes. C'est là que les UV jouent un rôle crucial dans la désinfection de l'eau .

What is a UV water filtration system?

A UV water filtration system is a point-of-entry or point-of-use device that passes water beside a high-output ultraviolet (UV-C) lamp. The UV light scrambles the DNA of bacteria, viruses, and protozoa so they can't reproduce or infect. It disinfects your water without adding chemicals, altering its taste, or leaving any byproducts behind.

Because UV on its own doesn't remove sediment or dissolved solids, most systems pair the UV chamber with a pre-filter for complete water treatment.

How to choose the right UV water filtration system

The right UV water filtration system depends on your flow rate and application:

  • Flow rate (GPM): Match the system's rated gallons per minute to your peak demand. Our range runs from ~1 GPM point-of-use units to 200+ GPM commercial systems.
  • Whole-house vs. point-of-use: Point-of-entry systems treat every drop entering a building; point-of-use units treat a single tap or appliance.
  • Water quality: Cloudy or high-sediment water needs pre-filtration first, so the UV light can reach every microorganism.
  • Certification: For drinking-water applications, look for NSF-validated systems (e.g. NSF Class A).

FAQs

Yes. UV-C light inactivates up to 99.99% of bacteria, viruses, and protozoa - including chlorine-resistant Giardia and Cryptosporidium - by disrupting their DNA so they can't reproduce.

No - UV disinfects but doesn't filter out sediment, metals, or dissolved chemicals. Pair your UV system with a sediment pre-filter (and carbon or reverse osmosis if needed) for complete treatment.

Yes. UV lamps gradually lose intensity and are typically replaced about once a year to maintain effective disinfection, even if the lamp still glows.
