The UV Disinfection System is designed specifically to use ultraviolet light to sanitize water by destroying or inactivating harmful microorganisms, including bacteria, viruses, and protozoa. This process works by exposing the pathogens to UV light, which disrupts their DNA or RNA, rendering them unable to reproduce and cause illness.

This technology is widely recognized for its effectiveness and is often employed in both residential and municipal water treatment applications. Its primary advantage is that it does not introduce chemicals into the water, making it an environmentally friendly choice for disinfection.

In contrast, the other systems mentioned do not use UV light for pathogen elimination. An Automatic Leak Control Valve is focused on detecting and preventing leaks; a Filtration System generally works by physically removing particulates from water; and a Pre-filtration System serves to remove larger particles before water undergoes further treatment processes. Therefore, the UV Disinfection System is the correct choice for applications specifically targeting pathogen elimination through ultraviolet light.
