In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute
(ANSI) publishes a series of snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow: Water Filtration
According to the Environmental Protection Agency
(EPA), Americans collectively drink more than one billion glasses of tap water every day. But before drinking water is deemed safe for human consumption, it must be filtered. To ensure the filtration process is effective and results in safe drinking water, the American Water Works Association
(AWWA) recently released AWWA B101-2012
, Precoat Filter Media
. The revised ANS covers disposable filter materials used to precoat filters for water supply service applications. Revisions to the standard include the addition and revision of definitions, as well as revisions to typical physical and typical chemical properties of precoat media used in water treatment. An ANSI organizational member and accredited standards developer, AWWA works to unite the entire water community to protect public health and welfare, and provide safe, sufficient, and sustainable water for all. AWWA initiatives include advancing education, science, management, government policies, technology, and standards for the water industry.
