식수 시스템 부품을 위한 NSF-61 증명서가 최근 Bilfinger Water Technologies의 Triton®Underdrain을 승인했다고 발표했다. 승인된 증명서는 공공 위생 관리, 시설과 미국, 캐나다와 다른나라들의 규제와 식수 제공에 사용하기 위한 Triton Underdrains의 적합성에 대한 강한 보증이다.

Bilfinger's Water Treatment Business Unit.의 부사장인 Lauria는 Triton Underdrains는 물이 분배 시스템으로 보내지기전 사람의 건강 보호를 위한 마지막 여과 단계의 여러 가지 경우에서 광범위하게 사용된다고 밝혔다.

Innovative underdrain technology receives NSF-61 certification

NSF/ANSI Standard 61 (NSF-61) certification for drinking water system components has recently been granted to Bilfinger Water Technologies' Triton®Underdrains. Achieving certification under NSF-61 is a strong assurance for public health officials, utilities and regulators across the U.S., Canada and other countries of the suitability of Triton Underdrains for use in the drinking water supply.

"There is a growing trend for all underdrain projects to conform to this standard," said Jim Lauria, senior vice director of Bilfinger's Water Treatment Business Unit. "NSF-61 testing is extremely rigorous, ensuring that the underdrains themselves, as well as all seals, gaskets and welding materials do not add contaminants to the drinking water supply. When it comes to specifying equipment for a new project or a retrofit, NSF-61 certification is a great point of reference for engineers, operators and regulators."

Lauria says Triton Underdrains are used in a wide variety of drinking water applications, in many cases as the final filtration step in safeguarding human health before water is sent to the distribution system. In addition, they often reliably protect sensitive downstream systems including reverse-osmosis (RO) membranes and other fine-filtration technologies. They are also used in conjunction with granular activated carbon (GAC) for the removal of disinfection byproducts (DBPs), taste and odor in drinking water worldwide.

He adds that Triton Underdrains are integral components in tertiary water treatment systems designed to meet California's Title 22 Water Recycling Criteria for discharge of treated water into the environment.

"We see a lot of installations in retrofit applications to meet Title 22 regulations," Lauria said. "It's a great testimony to the quality of this often-unsung piece of water treatment technology -- the underdrains that support the filtration media for water going to non-potable water applications like irrigation and industrial cooling systems."
