글로벌 공공 보건 조직인 NSF는 국제 평가 시 최초의 합의를 바탕으로 공공식수 공급 시 크립토스포리디움(Cryptosporidium)을 제거한 여과 기술의 성능을 평가하기 위한 미국 국제 표준법을 발표했다.

새로운 기준(NSF/ANSI 419)은 공공 식수 장비의 성능·여과과정의 상태의 시험과정을 간소화해 제조업체에 대한 시간 및 비용을 절감하고, 연방의 규제 요구사항과 준수사항을 점검한다.

 

 

 

Global public health organization NSF International has published the first consensus-based American National Standard to evaluate the performance of municipal water filtration technologies in removing Cryptosporidium from public drinking water supplies. The new standard - NSF/ANSI 419: Public Drinking Water Equipment Performance Filtration incorporates state and federal regulatory requirements, assisting state regulators in verifying compliance while reducing time and costs for manufacturers by streamlining the testing process.

 

Products from Dow Chemical Company, Hydranautics, Hyflux Limited, Inge GmbH and Qua Group LLC are the first to earn certification to NSF/ANSI 419. Several other water filtration technologies are currently undergoing the testing and certification process.

 

Municipal water treatment plants that use surface waters such as lakes, rivers and streams as a source of public drinking water are required to filter out microorganisms and bacteria such as Cryptosporidium unless exempted by the U.S. Environmental Protection Agency (EPA). To ensure Cryptosporidium is effectively removed from public drinking water, the EPA created the Long Term 2 Enhanced Surface Water Treatment Rule (LT2), which applies to all public water systems that use surface water or ground water that is under the direct influence of surface water.

 

The NSF/ANSI 419 standard incorporates the EPA LT2 Rule as well as other federal and state requirements such as certification to NSF/ANSI 61: Drinking Water System Components Health Effects, which sets contaminant limits for components that come into contact with drinking water such as plumbing components and pipes. By incorporating all regulatory requirements into one standard, NSF International is able to streamline the testing and certification process for these technologies while simplifying the purchasing process for municipal water treatment facilities.

 

“Water treatment technologies certified to the NSF/ANSI 419 standard have been tested to verify they effectively remove Cryptosporidium in drinking water, which is known to cause gastrointestinal illness. Instead of every state drinking water agency having to review each validation report for each product, state regulators can now verify compliance through the official listings found on NSF’s website,” said Clif McLellan, Vice President of NSF International’s Global Water Division.

 

NSF International developed the NSF/ANSI 419 standard utilizing nearly two decades of experience managing the U.S. Environmental Protection Agency’s Environmental Technology Verification Drinking Water Systems Center (ETV DWSC) with balanced input from industry, regulatory and end-user groups. The standard covers microfiltration, ultrafiltration and nanofiltration systems as well as bag and cartridge filtration systems used in the treatment or production of public drinking water.
