Dow Introduces ADSORBSIA™ Titanium-Based Adsorbent Media At WQA Aquatech Show

New Arsenic Removal Product Will Help Customers Achieve EPA Compliance

Las Vegas, NV - March 30, 2005

The Dow Chemical Company has launched ADSORBSIA™, a new arsenic removal media that offers improved performance and cost advantages over traditional iron oxide-based adsorbent media at this year's WQA Aquatech show in Las Vegas, Nevada. Now available in North America, ADSORBIA 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. "Dow's world class product development capabilities were able to leverage the unique properties of titanium to offer performance far superior to traditional adsorbent media. The combination of high capacity and superior kinetics make ADSORBSIA media cost effective, in terms of both initial capital cost and ongoing operations and maintenance expenses. Adding this line of media to Dow's portfolio is one more way we can deliver on our commitment to help our customers deliver the highest quality water at the lowest total cost."

ADSORBSIA's improved capabilities over iron-oxide based media include a Nanocrystalline structure that results in faster kinetics, allowing for smaller diameter vessels and a smaller system footprint. ADSORBSIA is also the highest capacity media in a wide range of water conditions and features a dry, white granule that is easily installed and maintained. It removes both As(V) and As(III) without pretreatment, is effective across a wide pH range, and exhibits a stable performance during pH fluctuations. It is available in powder form.

ADSORBSIA media's high capacity makes it an ideal, non-regenerable single-use product; a convenience for small or mid-sized systems. It offers an affordable, easy to operate approach, especially for small or mid-sized systems. Eliminating regeneration means avoiding the hassles and cost of chemical storage and usage while eliminating waste stream disposal issues. ADSORBSIA media's strong affinity for arsenic also allows the media to maintain a strong hold on the removed arsenic, allowing for easier and safer disposal. ADSORBSIA media also features a longer useful life than traditional adsorbent media, for a more productive, cost-advantaged operation.
