미국 전역에 분포되어 있는 상·하수도 시설이 자신들의 기술과 수처리 설비가 기준에 부합하면서 NSF/ANSI 지정 기준61의 인증을 획득하였다. 'NSF/ANSI 기준61의 음용수 시스템 요건-건강 보건'은 음용수 처리용 화학 약품을 포함하는 물질, 설비, 제품, 시스템의 건강에 대한 최저 영향 평가를 기반으로 적용된다.

이 기준은 예를 들어 적외선이 제품 내에 작동하는 설비를 노쇄하게 만들지 못하도록 한다. 이와 비슷하게 Neptune-Benson 사 소유의 Engineered Treatment Systems(ETS) 또한 적외선 음용수 처리 설비를 통해 본 인증을 획득한 것으로 알려졌다.

BEAVER, WI, Aug. 9, 2013 -- A number of water and wastewater utilities across the United States are certified as NSF/ANSI Standard 61 compliant for their technology and treatment systems. NSF/ANSI Standard 61 Drinking Water System Components - Health Effects is the standard that establishes the minimum health effects requirements for materials, components, products or systems that contain drinking water treatment chemicals.

This standard, for example ensures that ultraviolet (UV) light does not degrade components used within the products. Likewise, for Engineered Treatment Systems (ETS), a wholly owned subsidiary of Neptune-Benson, this certification was provided for its UV drinking water systems.

ETS specializes in the application of UV light, offering both medium pressure and low pressure amalgam lamp technologies in applications from a few GPM to full-scale water treatment plants treating flows of 30 MGD in a single chamber. The company provides solutions for both new installations and retrofits of existing systems, in a range of simple to footprint-challenging environments. Further, their UV systems safeguard against chlorine tolerant microorganisms such as Cryptosporidium and Giardia.

The ETS UV disinfection system is ideal for drinking water and wastewater treatmet, pharmaceutical applications, petrochemical fields, food and beverage industries, pulp and paper plants, aquaculture, and even pool disinfection.
