Ultraviolet (UV) Purification Systems
Ultraviolet systems can destroy 99.99% of harmful microorganisms without adding chemicals or changing your water’s taste or odor. A safe, clean, easy-to-maintain
method of assuring that water is free of bacteria, it is one of the four methods of disinfection approved by the United States FDA. Briefly, Ultraviolet or “UV” is a type of energy found in the electromagnetic spectrum, lying between x-rays and visible light. It is one of the four methods of disinfection approved by the United States FDA. UV disinfects when its light comes into contact with microorganisms. The Ultraviolet energy attacks the genetic core of the microorganism and rearranges the DNA /RNA eliminating the microorganism's ability to reproduce. If the microorganism can no longer reproduce, it cannot replicate, therefore it cannot infect other organisms with which has contact. UV has proven to be a quick, reliable and cost effective method of disinfecting water for both point of use and point of entry. Learn more about Ultraviolet Water Purification here.
Selecting your UV System: The quality or appropriateness of both the UV light and of the 'contact ', are crucial to accomplish disinfection. It is important to properly 'size' the UV based upon the application. The contact disinfectant property of UV light energy is measured in microwatt-seconds per square centimeter (uw-sec/cm2). LOW PRESSURE lamps which are best suited for small intermittent flow applications. When selecting a system be aware of your use requirements (gallons per day) and your preferred flow rates. It is equally important to use a good pre-filter to remove any dirt or debris that may be present in the raw water supply. This dirt and debris can interfere with the effectiveness of the UV rays – virtually giving the microorganism a shield to protect them when passing the UV rays.
System manufacturers strongly recommend that any pre and post filters and the UV lamp be replaced on an annual basis or after 9,000 hours of use -- whichever comes first.
Not all UV Systems are created equally in terms of performance, quality and/or replacement component costs. ESP sells new systems as well offering replacement parts for the most widely recognized UV manufacturers presently in the market. We chose this group of manufacturers because we believe that they produce the best and most dependable systems on the market.
