Dow's ADSORBSIATM Titanium-Based Adsorbent Media awarded NSF Certification

19-05-2005: ADSORBSIA titanium-based arsenic removal media, recently introduced by The Dow Chemical Company, is now certified by the NSF, under NSF/ANSI standard 61 for use in drinking water applications. This NSF certification is without limitations pertaining to flow rate or rinse requirements. This provides maximum flexibility in design allowing for lower cost systems.

ADSORBSIA arsenic removal media offers improved performance and cost advantages over activated alumina or iron oxide-based adsorbent media. Currently available in North America, ADSORBSIA media is designed to help municipalities comply with pending EPA regulations which will require municipal drinking water in the United States to have arsenic levels below 10 parts per billion (ppb), down substantially from the currently acceptable level of 50 ppb. The new regulations go into effect in 2006.

"We expect ADSORBSIA titanium-based media to quickly become the standard for municipalities as they seek to meet the new EPA regulation," said Dan Rice, project manager, Liquid Separations New Business Development. "ANSI 61 certification shows how Dow was able to leverage the unique properties of titanium to offer performance far superior to traditional adsorbent media while still providing the high quality water required by the standard. This certification is the latest example of our commitment to help our customers deliver the highest quality water at the lowest total cost."

ADSORBSIA arsenic removal media features a nanocrystalline structure that helps provide faster kinetics allowing for smaller diameter vessels and a smaller system footprint driving lower capital and operating costs. ADSORBSIA media offers the highest capacity in a wide range of water conditions. Higher capacity means longer media life and fewer media changeouts. When replacement it required, the fact that ADSORBSIA is sold as a dry, free-flowing white granule, makes it easy to install and maintain. Removing both As(V) and As(III) without pretreatment, ADSORBSIA media is effective across a wide pH range, and exhibits a stable performance during pH fluctuations.
