Ultraviolet (UV) Water Purifier

Ultraviolet (UV) Water Purifier is products of a complex science. UV light is a wavelength of light which is exists between the light that is visible and the x-rays on the electromagnetic spectrum. There are three subcategories of UV, which are UV-A, UV-B, and UV-C. UV-A and UV-B are the UV light that are responsible for people’s suntan or any sunburn. UV-C light is a much more damaging form of UV light and has a much higher energy. The UV-C is the light that is being used in the Ultraviolet (UV) water purifier systems.

UV-C light is a very damaging and very powerful form of UV light. The UV-C light is able to penetrate through living cell and would be able to damage the organism DNA. DNA (deoxyribonucleic acid) responsibility is to direct the activities in a living cell. All living cell to function properly need DNA. UV-C light with the ability to penetrate through the living cell and attack the DNA stops the replication of the DNA. This actually preventing the living cell from reproducing and causing bacterial or viral cell cannot reproduce and the bacterial or viral cells will not be able to cause infection.

The process of ultraviolet water purifier is to expose ultraviolet light and to make the microorganisms not able to reproduce and rendering them harmlessly to anybody that drinks the water.

There are two types of UV water purifiers that are available in the market. Point of entry, which could be installed on the main water line to purify all the water passing through and point of use, which the would purify water at a single faucet.

UV water purifier will not turn muddy water to clear, it will not eliminate chemicals and it will not change the taste or smell of the water. For these reason it is often necessary to install a water filter before the UV water purifier to purify the water.

Portable UV water purifier may be taken for camping or hiking. Some of the UV water purifier can run off of batteries or solar power. These types of UV water purifier would be very effective for traveling.

UV water purifier manufactures are producing different sizes of UV water purifier’s models. A longer UV lamp would be required for higher water flow rates and a shorter UV lamp is usable for slower flow rates since the water that is treated would resides for a longer period in the UV system.
