UVdesinfektsiooni

UVdesinfektsiooni, also known as ultraviolet disinfection, is a sterilization method that uses ultraviolet light to kill microorganisms. This process is achieved by exposing water, air, or surfaces to germicidal ultraviolet (UV-C) light. The UV-C light, specifically at a wavelength of 254 nanometers, disrupts the DNA and RNA of bacteria, viruses, and other pathogens, rendering them unable to reproduce and causing their inactivation.

The effectiveness of UVdesinfektsiooni depends on several factors, including the intensity of the UV light, the exposure time, and the clarity of the medium being disinfected. For water purification, turbidity can shield microorganisms from the UV light, reducing its efficacy. Therefore, pre-filtration is often employed.

UVdesinfektsiooni is a chemical-free disinfection method, meaning it does not introduce harmful byproducts into the environment or the treated substance. This makes it an attractive option for applications where chemical treatments are undesirable, such as in drinking water treatment, food processing, and healthcare settings for sterilizing medical equipment and purifying air.

The technology typically involves a UV lamp housed in a chamber through which the substance to be disinfected flows or is exposed. Common applications include household water purifiers, industrial wastewater treatment, and air purification systems in hospitals and public buildings. While highly effective against a broad spectrum of microorganisms, UVdesinfektsiooni does not remove dissolved chemicals or inorganic contaminants.
