The portion of the electro-magnetic spectrum having wavelengths included between 100 and 400 nm is defined as ultraviolet radiation (UV). UV-C is the subset of wave lengths included between 100 and 280 nm. UV-C has significant germicidal properties. The peak effectiveness of germicidal occurs near the wavelength of 265nm.
HOW DOES UV WORK?
The high germicidal power of UVC impacts RNA and DNA. The alteration, induced by the UV-C irradiation, of some chemical links present among nucleotids is able to change the information contained and conveyed by DNA, these alterations prevent its normal activity and this irreversibly leads to the cellular death.
HOW WELL DOES UV WORK?
To achieve the germicidal effects of UV, both the wave length (UVC) and its intensity must be optimized. A correctly designed and sized UV sterilizer provides a lethal dose of UVC sufficient for eliminating most micro-organisms.
WHAT ARE THE BENEFITS OF UV
Ultraviolet Sterilization has several advantages over many other technologies:
- UV is “environmentally friendly” – safe for aquatic life!
- No danger of over-dosing
- No change to the taste or smell of water
- Immediate impact
- Fully compatibility with the other technologies (filtration, softening, etc) for a complete treatment of water
- Cost efficient due to the low electrical consumption and minimal required servicing.
- Avoids the use of any chemical substances
