Looking for a more convenient and cost effective option for removing arsenic in drinking water? ADSORBSIA GTO titanium-based media from Dow is now available in North America to help municipalities comply with the 2006 EPA regulation. The new media has improved capabilities compared to all other commercially available media. Advantages include:

  • Highest capacity media over a wide range of water conditions
  • Nanocrystalline structure results in fastest kinetics allowing for smaller diameter vessels and a smaller system footprint
  • Removes both As(III) and As(V) across a wide pH range without use of pretreatment
  • Stable performance during pH fluctuations
  • Dry, white granule that is easily installed and maintained
  • Also available in the powder form (ADSORBSIA PTO™ media)

ADSORBSIA GTO media's high capacity makes it an ideal non-regenerable single-use product. 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 GTO 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 GTO media also features a longer useful life than traditional adsorbent media, for more productive, cost-advantaged operation.
