FORT WASHINGTON, PA, Sept. 6, 2005 -- The SORB 33® arsenic removal technology and Bayoxide® E33 arsenic removal media from Severn Trent Services have been selected for use by Nellis Air Force Base at two of its water treatment facilities outside of Las Vegas, Nev. Total arsenic for the base's 600 gallon per minute (gpm) and 550 gpm water treatment facilities has been measured at between 19 and 32 parts per billion (ppb) compared to the new EPA standard of 10 ppb. Installation of the new arsenic removal system will take place prior to the January 2006 compliance deadline for the new maximum contaminant level (MCL). The contract is valued at $502,000.

Severn Trent Services developed the SORB 33 process to reduce arsenic contamination across a range of water treatment application sizes, and the technology has been commercially proven to effectively and economically meet the stringent new government MCL standard. Bayoxide E33 is a dry, robust, ferric oxide media designed with a high capacity for arsenic, providing long operating cycles and low operating costs. Compared to competitive technologies, Bayoxide E33 offers the lowest capital cost while providing ease of operation and maintenance. The media has been permitted for use by health and environmental agencies in 15 states, more than any other arsenic removal technology.
