How do ultraviolet rays inactivate microorganisms?
Time:12.04.2021Reading times:1089

Ultraviolet disinfection is the use of appropriate wavelength of ultraviolet light can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, resulting in growth cell death and (or) regenerative cell death, to achieve the effect of disinfection. Ultraviolet disinfection technology is based on modern epidemic prevention, medicine and photodynamics. It uses specially designed UVC band ultraviolet light with high efficiency, high intensity and long life to irradiate the running water and directly kill all kinds of bacteria, viruses, parasites, algae and other pathogens in the water.

Mechanism of ultraviolet anti virus

The results show that ultraviolet radiation is mainly through the protection of microorganisms ( Bacteria, viruses, spores and other pathogens ) The function of nucleic acid is damaged and destroyed by radiation, and the microorganism is killed, so as to achieve the purpose of disinfection. The effect of ultraviolet radiation on nucleic acid can lead to the breaking of bonds and chains, the cross-linking between strands and the formation of photochemical products, thus changing the biological activity of DNA and making microorganisms unable to replicate. This kind of UV damage is also fatal
