Gentle on people and the environment
Our hero: UV-C radiation
UV radiation is a safe, chemical-free and reliable method of disinfection in modern water treatment. ProMinent Dulcodes® UV systems exploit the safety and reliability of UV disinfection in a wide range of applications. Scientific research and the many systems successfully in operation prove that UV is ideally suited to water disinfection.
Our hero: UV-C radiation
No one wants germs - and UV-C radiation in particular, with a wavelength ranging from 240 to 280 nm, attacks the vital DNA of the bacteria directly. The bacteria lose their reproduction capability and are destroyed. Even parasites, like Cryptosporidia or Giardia, which are extremely resistant to chemical disinfectants, are efficiently reduced.
Not just for potable water
Photochemical reactions triggered by UV are used in other ProMinent applications too. The undesirable presence of combined chlorine in swimming pool water is reduced by UV radiation, achieving significant savings in fresh water. Oxidants, such as ozone, chlorine or chlorine dioxide, are reliably reduced in the production water used in the food and pharmaceutical industries, eliminating the need for expensive active carbon filters.
The advantages of UV treatment
Immediate and safe disinfection without the addition of chemicals. This results in highly effective disinfection regardless of the pH value. No undesirable substances are formed. The odour and taste of the water are not impaired. There is no need to store and handle chemicals. No reaction vessel or reaction tanks are required. A ProMinent UV system takes up very little space and keeps investment and operating costs low while delivering exceptional reliability and performance.
