Understanding UV Technology in Depth

Ultraviolet (UV) light is a form of electromagnetic radiation, which plays a crucial role in water purification. This section delves into how UV light interacts with microorganisms and the science behind its sterilization capabilities.

How UV Light Kills Microorganisms

UV light works by damaging the DNA or RNA of microorganisms such as bacteria, viruses, and protozoa. When exposed to UV light for a sufficient duration, these organisms can no longer reproduce or infect. This process is known as photodimerization, where UV light causes the formation of covalent bonds between adjacent thymine bases in DNA, resulting in mutations that render the microorganisms inactive.

The Role of Wavelength

The effectiveness of UV sterilization is heavily influenced by the wavelength of the UV light. The most effective range for disinfection is typically between 200 to 280 nanometers, specifically around 254 nanometers.
