Ultraviolet light at the germicidal wavelength of 253.7 nanometers alters the genetic (DNA) material in cells so that bacteria, viruses, molds, algae and other microorganisms can no longer reproduce. The microorganisms are considered dead, and the risk of disease from them is eliminated.

• UV is nature's way of purification
• Environmentally positive - no chemicals needed
• Greater effectiveness on a wide range of pathogens
• No residual properties left in treated water
• Simple operation
• Minimal system maintenance requirements
• Lowest operating cost amongst disinfection processes
• Reduced capital costs
