Gecom has supplied water treatment systems that uses ADSORBSIA GTO arsenic removal media from The Dow Chemical Company. The company said that the arsenic level in over 432,000 gallons of potable water supplied daily to 3,100 households in Sedona, has been lowered from 25ppb to less than 10ppb.
Alan Greenberg, product line manager of Dow Water & Process Solutions, said: When choosing the equipment and the technology for arsenic removal, water utilities look for a good return on their investment in terms of performance and economics. ADSORBSIA media provides a reliable, cost-advantaged and flexible solution that works equally well in both brand new installations and in previously installed equipment that was designed for other media.
The company claims that besides reducing arsenic levels, ADSORBSIA media offers a number of other environmental and social benefits. Eliminating the regeneration step frees operators from the hassles and cost of chemical storage and usage, and from waste stream disposal issues. Also, ADSORBSIA media maintains a strong hold on the removed arsenic, promoting easier and safer disposal. The nanocrystalline structure of ADSORBSIA media also enables faster kinetics, allowing for smaller diameter vessels and a smaller system footprint.
