What technology uses UV light to disinfect water?

Ultraviolet disinfection systems employ UV light to effectively disinfect water by inactivating harmful microorganisms such as bacteria, viruses, and protozoa. The technology works by exposing the water to UV light at a specific wavelength, typically around 254 nanometers, which disrupts the DNA of the pathogens, preventing them from replicating and causing infection. This method is recognized for its efficiency, low chemical usage, and not introducing harmful byproducts into the water, making it a popular choice for water treatment.

In contrast, chlorination systems utilize chemicals to disinfect water, which results in the formation of chlorine byproducts and may not be as effective against certain types of pathogens as UV light. Filtration systems primarily remove physical particles and sediment from water, rather than disinfecting it through the use of light. Lastly, reverse osmosis systems focus on separating contaminants from water using a semi-permeable membrane rather than utilizing UV light for disinfection purposes. Therefore, the technology that specifically leverages the power of UV light for disinfection is undoubtedly ultraviolet disinfection systems.
