AdEdge Receives “Project of the Year” Award from American Public Works Association - New Mexico

May 19, 2006

The American Public Works Association - New Mexico Chapter selected an AdEdge Technologies, Inc. arsenic treatment system as “Project of the Year”. The project was a water system improvement for the Green Ridge community located in Tijeras, N.M.

The Green Ridge system had been without potable water for three years. Local residents hauled from 100 to 300 gal per week to meet their water needs. The groundwater resource in Tijeras was determined to contain high arsenic concentrations that were above the proposed maximum contaminant level (MCL). The arsenic concentration was 95 ppb, and the pH was 8.6.

Souder Miller & Associates (SMA) chose AdEdge to execute the turnkey project. AdEdge worked closely with SMA to provide submittals and plans for permitting and operating the 20 gal per minute (gpm) treatment system for arsenic. The system was fabricated and installed in June 2005.

The AdEdge arsenic treatment system consists of a skid-mounted Adsorption Package Unit (APU) unit (Model APU-20LL) rated for 20 gpm. Arsenic treatment occurs in a series (i.e., lead/lag reversible) configuration. Groundwater is pumped from the water-supply well through a pre-filter, through the APU and into a 53,000-gal storage tank. From the storage tank, groundwater flows through booster pumps, a hydropneumatic tank, and into the distribution system.

The 24-inch diameter APU vessels each contain approximately 8 cu ft of Bayoxide E33® adsorption media. Bayoxide E33 is a granular ferric oxide (GFO) media that has been in commercial use since 1999. AdEdge has deployed GFO media in over 70 public water and commercial systems throughout the U.S. and in over 1,500 residential applications since 2002.

The skid-mounted pre-engineered APU system is equipped with automatic controls, backwashing features, switches, gauges and sample ports for complete functioning packaged unit. Instrumentation is provided on a control panel to measure critical operating parameters. Total gallon throughput and flow rate for each unit is measured continuously with dedicated flow totalizing meters. The AdEdge adsorption system does not require any chemicals or regeneration, and the process does not generate liquid or hazardous waste.

The system was started up and placed into operation in June 2005 and has been operating for over 11 months treating arsenic well below the standard of 10 ppb. System oversight is provided by the site’s certified water treatment operator. A special open-house event and ribbon cutting ceremony to celebrate this new treatment milestone featuring Senator Pete Domenici was held in August 2005 with the community, local leaders and the press.
