Dear Gloria Fernadez,UV ...

Dear Gloria Fernadez,

UV technology offers an added sense of assurance that the surface water is microbially free and clear without the unpleasant taste and odor of chemical disinfectants or potential chemical disinfection by-products.UV is a proven and safe alternative for primary disinfection as it is free of the harmful by-products associated with chemical disinfection. UV also has the added benefit of not compromising the taste, color or odor of water.V systems are being integrated with existing chemical disinfection treatments. UV works by irradiating or disrupting the DNA of microorganisms, rendering them unable to reproduce. It’s generally accepted that microbial DNA absorbs UV most effectively at 265 nanometers (nm), a wavelength that medium pressure lamps produce in abundance. In addition to emitting UV at this optimum peak wavelength, medium pressure lamps also emit UV over a very broad range of wavelengths (about 185-400 nm). Independent research has shown that, with proper pretreatment and a well-maintained UV disinfection system, this broad output causes permanent inactivation of both pathogenic and non-pathogenic microorganisms such as  Escherichia coli,  also known as  E. coli .Low pressure UV lamps, the common alternative to medium pressure lamps, produce just a single peak of UV output at 254 nm. While also having a strong germicidal effect, it has been shown that some microorganisms are able to repair or reactivate themselves after exposure to UV from low pressure lamps, especially if they’re subsequently exposed to sunlight. This is known as photo reactivation.
