Ultraviolet Disinfection
UV Disinfection – Powerful & Chemical-Free Protection
UV disinfection is highly effective in the 200-300 nm wavelength range, with UVC radiation delivering a strong bactericidal effect by disrupting microbial DNA, preventing reproduction, and inactivating living cells.
Key Benefits:
✔ Rapid Disinfection – Viruses, bacteria, yeasts, and fungi are neutralized within seconds.
✔ Chemical-Free & Eco-Friendly – Eliminates the need for harmful chemicals, ensuring safe and sustainable treatment.
✔ No Resistance Development – Microorganisms cannot build resistance to UV radiation, making it a long-term, reliable solution.
With high-intensity irradiance, UV disinfection provides safe, efficient, and environmentally friendly water and air treatment for municipal and industrial applications.
What is UV-C?
Ultraviolet (UV) Light – A Powerful Disinfectant
Ultraviolet (UV) light is a type of electromagnetic radiation within the 200-400 nm spectrum. Although invisible to the human eye, it is widely used for disinfection and sterilization.
Three Ranges of UV Light:
✔ UV-A (315-400 nm) – Longest wavelength, primarily responsible for skin tanning and aging.
✔ UV-B (280-315 nm) – Medium wavelength, causes sunburn and plays a role in vitamin D synthesis.
✔ UV-C (200-280 nm) – Shortest wavelength, with strong bactericidal properties, making it the most effective for disinfection.
UV-C radiation is commonly used in water, air, and surface disinfection, as it effectively destroys bacteria, viruses, and other microorganisms without the use of chemicals.
UV-C Disinfection – How It Works
UV-C light is germicidal, meaning it effectively kills microorganisms such as bacteria and viruses by disrupting their genetic material.
How UV Disinfection Works:
✔ DNA & RNA Damage – UV-C radiation modifies genetic material, preventing microorganisms from reproducing.
✔ Formation of Thymine & Uracil Dimers –
🔹 In DNA, UV-C induces thymine dimers, leading to mutations that inactivate bacteria and viruses.
🔹 In RNA-based viruses, UV-C triggers uracil dimer formation, disrupting replication.
✔ Rapid & Chemical-Free Disinfection – Microbes are neutralized within seconds, making UV-C a safe, efficient, and eco-friendly method for water, air, and surface sterilization.
With proven germicidal effects, UV-C technology provides reliable, chemical-free disinfection for municipal, industrial, and healthcare applications.
