Ultraviolet light kills microorganisms quickly and effectively through physical processes. When bacteria and viruses are exposed to the germicidal wavelength of ultraviolet light, the molecular bonds in the microbial DNA will be destroyed, and the resulting dimers can disable the bacteria. The effectiveness of germicidal ultraviolet rays depends on the length of time the microorganisms are exposed to ultraviolet rays. In air and surface disinfection applications, the UV effect is estimated by calculating the UV dose delivered to the microbial population. UV dose = UV intensity (expressed in energy per unit area) × exposure time In many systems, repeated cycles of air or water are used to achieve exposure of microorganisms to UV rays. This can ensure that after multiple passes, the ultraviolet rays are effective for the largest number of microorganisms, and the molecular bonds of the microbial DNA are destroyed after multiple irradiations.
While performing UVC disinfection, UVC will provide ultraviolet radiation, which is not safe in the working environment at this time. Ultraviolet rays are harmful to the skin and eyes, so always avoid direct exposure to UVC. However, UVC can provide residue-free disinfection, so there is no need to worry about dangerous residues that need to be wiped or neutralized after disinfection.
The disinfection process is environmentally friendly because there are no hazardous or toxic chemicals that require special storage or handling. Since there is no need to add chemicals to the air or water during the disinfection process, the process will not produce any by-products. In addition, UV LEDs do not require special treatment or disposal, making this disinfection system the best green substitute for all disinfectants.
