Ultraviolet light is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for summer tans. Too much exposure to radiation damages the living tissue. Most of the natural UV light people encounter comes from the sun. However, only 10% of sunlight is UV, and only about one-third of this penetrates the atmosphere to reach the ground. In the visible part of the spectrum, wavelength decreases and the energy of the electromagnetic waves increases from red through orange, yellow, green, blue and violet, so UV light has a shorter wavelength and more power than violet light.
What is the purpose of UV in Water Treatment?
Ultraviolet water purification is the most effective method to disinfecting the bacteria present in water. UV light protect home water from pathogens and also used to destroy illness-causing microorganisms by attacking their genetic core. Almost 99.9% of harmful bacteria killed by UV light without adding chemicals and changing your water’s taste or odor. UV light system is mostly used with other forms of filtration such as reverse osmosis systems or carbon block filters. UV light system is effective in killing bacteria from water. This system is highly recommended to homeowners who want to remove some bacteria from water. It is advised not to use any chemical to remove bacteria such as chlorine because of the toxic byproducts they create.
Ultraviolet purification is not enough to purify water down to drinking water purposes. This is because UV radiation is only effective for treating bacteria and viruses. This system doesn’t eliminate heavy materials and other chemicals from water. UV systems are mostly paired with Reverse Osmosis systems to provide a complete purification process for the safest drinking water.
