Filtration media combines physical entrapment of fine particles with filtering of contaminants to improve water clarity
NSF Intl. has certified Zeotech’s Zeobrite Xtreme filtration media for use in sand filters in swimming pools and other recreational water facilities and for use in municipal drinking water treatment. Zeotech is the only company to have zeolite filtration media certified by NSF Intl. for use in both drinking water and recreational water applications. Zeolite filtration media combines the physical entrapment of fine particles with filtering of contaminants to improve water clarity.
Zeotech Zeobrite Xtreme Certification to the NSF American National Standards for drinking water distribution (NSF/ANSI Standard 61) and recreational water treatment products (NSF/ANSI Standard 50) is required by most U.S. States, according to NSF Intl.
NSF/ANSI Standard 61: Drinking Water System Components -- Health Effects is the American National Standard for the health effects of materials, components and products that contact drinking water. The standard verifies that certified products will not add contaminants to drinking water that are in excess of one-tenth of U.S. Environmental Protection Agency (EPA) requirements.
NSF/ANSI Standard 50: Equipment for Pools, Spas, Hot Tubs and Other Recreational Water Facilities is the American National Standard for water treatment products that are used in commercial swimming pools, spas and other recreational water facilities like water parks. The standard contains material safety, pressure loss, media cleanability and turbidity reduction requirements for products used in water filtration, circulation and treatment.
Zeolite media must perform as well as or better than sand when used in an NSF/ANSI Standard 50 certified sand filter to meet the NSF requirements.
“The certification of Zeobrite and Zeobrite Xtreme helps assure operators at drinking water treatment plants and recreational water facilities that the media are free from unwanted contaminants and filter as well as or better than sand,” said Dave Purkiss, general manager for NSF’s Water Treatment and Distribution Products program.
“We are excited that our new patent-pending Zeobrite Xtreme and our standard Zeobrite are the only zeolite products to be certified by NSF’s Drinking Water Distribution and Recreational Water Certification Programs, adding tremendous credibility to the Zeobrite brand,” said Ronnie Coufal, senior vice president – marketing for Zeotech Corp. “The NSF/ANSI 50 Turbidity Reduction Test results for Zeobrite Xtreme also positions the product to rival other types of filter media for removal capability.”
