The influence of ultraviolet weather resistance test chamber on microorganisms

The ultraviolet weather resistance test chamber can be installed in various locations of the ultrapure water system. It is relatively simple to install or modify existing pipelines and vessels, which can achieve the lowest degree of production disturbance and the smallest footprint requirements. Depending on the purpose of use, the only work that requires regular maintenance is to replace the UV lamp tube every 12 months, which can be completed by a simple operation by field staff. Once installed, the treatment plant can be operated 24 hours a day, without downtime for daily sanitary maintenance and disinfection of the system.

Ultraviolet light breaks the adenine and thiamine molecules of microbial deoxyribonucleic acid (DNA), preventing it from continuing to reproduce. The microorganisms can thus be killed without using chemicals. Although 254 nanometers is an effective disinfection wavelength, DNA can absorb ultraviolet light with a wavelength of 265 nanometers most effectively. Understanding the differences in the sterilization capabilities of these different wavelengths of ultraviolet light is the basis for designing ultraviolet disinfection equipment with good sterilization and high efficiency. In general, low-pressure systems are best used for small flow, intermittent systems, while medium-pressure technology is more suitable for high-velocity water disinfection.
