Ultraviolet light (or UV) is at the invisible, violet range of the electromagnetic spectrum. The water treatment industry uses a high-powered form of UV light called UV-C or "germicidal UV" to disinfect water from disease causing bacteria and protozoan cysts.
UV technology can be more effective than chemicals in destroying certain waterborne contaminants without altering the taste of the water. This makes it a practical process for treating water that is used for drinking and food preparation.
UV light disinfects by penetrating microorganisms and disrupting their DNA, preventing them from multiplying. The only function of a microorganism is to breed and produce colonies this is why when we ingest microorganisms they make us sick. Visit our 'How Ultraviolet Purification Works' guide to learn more.
