A » UV disinfection inactivates microorganisms by exposing them to ultraviolet light, which disrupts their DNA and RNA, preventing replication and rendering them harmless. This non-chemical method is effective against bacteria, viruses, and protozoa, ensuring safe water without altering taste or odor. The process requires precise UV light intensity and exposure time to ensure maximum microbial inactivation, making it a preferred method in water purification systems.

A »UV disinfection inactivates microorganisms by damaging their DNA with ultraviolet light, preventing them from reproducing. The UV light alters the DNA structure, making it impossible for the microorganisms to carry out their normal functions, effectively killing or inactivating them, and thus purifying the water.
