Bilfinger Water Technologies announced that its Triton® Underdrains have received NSF/ANSI Standard 61 (NSF-61) certification for drinking water system components. 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,” notes 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 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 points out. “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.”

Lauria says undergoing the demanding NSF-61 testing protocol is part of Bilfinger’s commitment to the North American market.

“Bilfinger is a global innovator in the water treatment industry, and we continue to develop and certify technology to help our customers meet the ever-changing regulatory environment in North America,” he says.  “Our commitment to innovation helps make water treatment facilities more efficient and effective, and also helps ensure their regulatory compliance—which is another key element in safeguarding our water supply and the environment.”

Triton Underdrains are a Johnson Screens product, a brand of Bilfinger Water Technologies. For more information, visit www.water.bilfinger.com
