Ultraviolet purification is a water treatment process that uses ultraviolet (UV) light to eliminate harmful microorganisms. This method works by exposing water to UV light, which disrupts the DNA of bacteria, viruses, and other pathogens, rendering them inactive and unable to reproduce. It is an effective way to ensure safe drinking water without the use of chemicals. This purification technique is commonly used in various settings, including municipal water treatment plants, household water filters, and aquarium systems. UV purification is favored for its speed and efficiency, as it requires minimal maintenance and does not alter the taste or quality of the water.
