Veolia Water Technologies & Solutions

Aquaray* Ultraviolet (UV) Systems

Environmentally safe and effective in a compact integratable design

Ultraviolet disinfection stands out as an environmentally safe and highly effective method for water treatment due to its ability to neutralize pathogens, without using harmful chemicals. The compact nature of UV systems easily integrate into existing water treatment plants, fitting various stages of the process without major modifications or space requirements. Veolia is at the forefront of UV technology, specializing in disinfection, water reuse, and recycling solutions. We're committed to delivering reliable, innovative solutions that address our clients' specific challenges across a wide range of applications.

How Does Ultraviolet Disinfection Work?

UV irradiation systems disinfect by inactivating pathogenic microorganisms, such as viruses, bacteria and parasites. In the UV-C light spectrum (200-280 nm), the wavelength 254nm has been proven to be the most efficient wavelength to inactivate micro-organisms by damaging the nucleic acids (DNA and RNA), which disrupts the organism’s ability to replicate.

In normal applications, UV has the advantage that no chemicals are added to the water being treated and that no disinfection by-products are formed. Due to the small foot print, the UV equipment can be easily integrated into most existing water treatment plants.

How does UV disinfection work?

UV-C Light Spectrum

UV irradiation systems disinfect by inactivating pathogenic microorganisms, such as viruses, bacteria and parasites. In the UV-C light spectrum (200-280 nm), the wavelength 254 nm has been proven to be the most efficient wavelength to inactivate microorganisms by damaging the nucleic acids deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), which disrupts the organism’s ability to replicate.

Chemical-Free Advantage

UV water treatment offers a significant advantage in typical applications due to its chemical-free approach. Unlike traditional disinfection methods, UV systems do not require the addition of chemicals to the water being treated, eliminating the formation of potentially harmful disinfection by-products. This makes UV treatment a safer and more environmentally friendly option.
