What is the role of ultraviolet (UV) radiation in the water purificati...
Ultraviolet water purification uses ultraviolet (UV) rays to penetrate the harmful pathogens in your home’s drinking water. The light does not necessarily destroy the organisms, but disables their ability to multiply. Ultraviolet light is invisible but we are exposed to it every day from all sources including the earth’s sun. Ultraviolet water purification is a simple but effective process that destroys around 99.99% of the harmful organisms in water. Aside from drinking water at homes, it is also used by untreated private water systems. UV water purification is usually done in conjunction with other forms of filtration such as reverse osmosis or carbon block.
