To understand how ultraviolet water purifiers work, there are a few concepts you need to now.
First, what is ultraviolet light?
Ultraviolet light is part of the light spectrum and is classified into three wavelength ranges: UV-A, UV-B and UV-C. For water disinfection, UV-C lamps (also referred to as germicidal ultraviolet) are best utilized because they produce energy at 254 nanometers, the most lethal to microorganisms in water.
Second, how does germicidal UV light purify?
Germicidal ultraviolet UV-C light deactivates the DNA of bacteria, virus, and other pathogens — thus destroying their ability to multiply and cause disease. Specifically, UV-C light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.
Finally, how do ultraviolet water purifiers work?
Our water purifiers contain one or more STER-L-RAY ® brand of germicidal ultraviolet (UV-C) lamps which are short wave, low pressure tubes that produce ultraviolet wavelengths lethal to microorganisms (such as bacteria, mold and virus). Water enters the chamber of the water purifier and flows into the annular space between the quartz sleeve and the chamber wall. The water is then exposed to the UV-C rays from the Ster-L-Ray germicidal lamp thereby deactivating the microorganisms. Water leaving the purifier is instantly ready for use.
