NSF International water quality and treatment experts will be presenting at the World Aquatic Health Conference October 11 in Norfolk, Va., according to a press release. Their presentations will cover the regulatory and testing considerations for evaluating the efficacy of ultraviolet (UV) and ozone water treatment technologies to help ensure the health and safety of pool and spa environments.
NSF International has helped UV and ozone water treatment technologies gain acceptance for drinking water and recreational water treatment applications by testing and certifying products against a NSF American National Standard, which covers both UV and ozone. Topics include: Understanding, Testing and Certification of UV Systems for Recreational and Drinking Water and Evaluating the Efficacy of Ozone Treatment Systems Against Protozoa, Bacteria and Viruses.
NSF has published NSF Standard 222 which specifically addresses the use of small to medium sized ozone generators for municipal drinking water applications. NSF laboratories also use an ozone UV process from Spartan Environmental Technologies to recycle water used in testing of water treatment equipment in their laboratories. The recycling of this water helped NSF’s facility to achieve higher LEEDS certification.
