By 2001, over 6,000 UV water treatment plants were operating in Europe. [67] Over time, UV costs have declined as researchers develop and use new UV methods to disinfect water and wastewater. Several countries have published regulations and guidance for the use of UV to disinfect drinking water supplies, including the US [68] [69] [70] and the ...
A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light. This short-wave ultraviolet light disrupts DNA base pairing , causing formation of pyrimidine dimers , and leads to the inactivation of bacteria , viruses , and protozoans .
Sterilization can be achieved using electromagnetic radiation, such as ultraviolet light (UV), X-rays, and gamma rays, or irradiation by subatomic particles such as electron beams. [57] Electromagnetic or particulate radiation can be energetic enough to ionize atoms or molecules ( ionizing radiation ), or less energetic atoms or molecules ( non ...

Unlike conventional germicidal UV-C lamps, which are limited to upper-room (above people's heads [8]) pathogen inactivation or use in unoccupied spaces, due to their negative effects on human skin and eyes, far-UVC is considered promising for whole-room pathogen inactivation due to its enhanced safety. The installation of far-UVC lights on ...
