UV Water treatment

     A relatively new technology for portable water treatment is the use of Ultraviolet (UV) light. UV technology has been used for decades by many cities in their municipal water treatment plants.  When exposed to the proper wavelength, the DNA of the microbes is affected such that they cannot reproduce. Without reproduction capabilities, the microbes can’t make you ill. A company called Hydro-Photon introduced the portable UV water purifier, with the brand name SteriPEN®. They market several models that can destroy over 99.9% of bacteria, viruses and protozoa such as giardia. These UV purifiers are effective and battery powered.

 

     The “Little Spring” water source described in my book  is too shallow to scoop water into your bottle, so you’ll need to use a ladle or other method. The water treated by UV needs to be as clear as possible to prevent pathogens from “hiding” behind sediment. It’s best to agitate the water during the treatment.  The optimum method for unclear water is to employ a two-step process by first filtering suspect water, thereby removing the particulates, prior to using UV purification.

    Thanks for the info. I’ve heard about this technology, but have not really looked into it as a portable solution. It sounds great as a two step system using a filter. I hope I can find a reliable system cheap enough.
