Adedge Technologies, Inc, a supplier of specialty adsorbent products and systems for arsenic removal from water and wastewater applications, and the U.S. Environmental Protection Agency (EPA) announced that Adedge was awarded three full-scale demonstration sites for its arsenic removal technology for municipal drinking water systems. The locations are Nambe Pueblo, N.M. (near Santa Fe), Rimrock, Ariz. (near Sedona), and Rollinsford, N.H. (near Portsmouth).
The EPA estimates that approximately 13 million people in the United States alone routinely drink water containing arsenic at concentrations greater than allowed under recently established government standards. The EPAs new arsenic rule requires treatment for all public drinking water systems with arsenic levels greater than 10 parts per billion (ppb), by January 2006. This represents a dramatic decrease from the current standard of 50 ppb. Small public water systems serving less than 10,000 people will be financially impacted most from the new arsenic rule. The EPA demonstration program is an aggressive program to further qualify commercially-ready technologies that result in significant cost savings over previous technologies.
Adedge Technologies relies on a patented granular ferric oxide technology developed by Bayer and marketed as Bayoxide E-33 to reduce arsenic contamination in small municipal and industrial applications. This media which has NSF 61 approval is an integral component in AdEdges line of AD-33ä
arsenic removal systems and products for small community and non-community drinking water systems.
"The ability to participate with the EPA to demonstrate these advantages further benefits small community water systems who have been very concerned about the high costs associated with earlier technologies and want low cost, simple solutions," stated Rich Cavagnaro, president of AdEdge.
