Pulsed UV dramatically enhances the advantages of ultraviolet light for water disinfection by delivering the light in high-intensity pulses that can be repeated many times per second as water moves through a reaction chamber. These advances have been the focus of research and testing for several years by academia, governments and industry because these pulses deliver the disinfection effects of UV at intensities thousands of times stronger than conventional UV systems and without the risks associated with chemicals such as chlorine. Research has further documented that pulsed UV is effective in dealing not only with bacteria but also a wide range of pathogens in water such as Cryptosporidium, which is of increasing concern to public health officials and against which chlorine has been found to be ineffective. The US Environmental Protection Agency and other world regulators have also begun restricting the use of chlorine due to the discovery of disinfection by-products that have been found to release carcinogenic volatile organic compounds. The LightStream breakthroughs resolved engineering issues previously complicating the cost-effective delivery and application of pulsing the UV light at peak power ranges in the millions of watts per pulse.
Patents are pending.
We believe the future of water must be one of safety, value and availability. Company officials said that LightStream products for municipal and industrial water treatment would be introduced globally in the 4th quarter of 2000. This portion of the DEP web site maintained by Gay Kreiser .
