Severn Trent Services provides arsenic removal technology in Arizona

Two SORB 33 arsenic removal systems and Bayoxide E33 arsenic removal media from Severn Trent Services have been selected for use by Adaman Mutual Water Company, located outside Phoenix, Ariz., at its Well #1B. The well, which delivers a maximum flow rate of 1200 GPM, had an arsenic level of 14 ppb. The new arsenic removal treatment system, with a treatment capacity of 550 GPM, will enable the company to reduce arsenic levels below the EPA arsenic standard for drinking water of 10 ppb...

• Arsenic removal system, which features SORB 33® technology and Bayoxide® E33 media, has been commercially proven effective for more than a decade

FORT WASHINGTON, PA, April 14, 2008 -- Two SORB 33® arsenic removal systems and Bayoxide® E33 arsenic removal media from Severn Trent Services have been selected for use by Adaman Mutual Water Company, located outside Phoenix, Ariz. near Luke Air Force Base, at its Well #1B. The well, which delivers a maximum flow rate of 1200 gallons per minute (GPM), had an arsenic level of 14 parts per billion (ppb). The new arsenic removal treatment system, with a treatment capacity of 550 GPM, will enable the company to reduce arsenic levels below the EPA arsenic standard for drinking water of 10 ppb. Hennesy Mechanical Sales LLC serves as the project's construction manager.

The SORB 33 process and technology developed by Severn Trent Services to reduce arsenic contamination has been commercially proven to effectively and economically meet the stringent government standard of 10 ppb across a range of water treatment applications. 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 24 states, more than any other arsenic removal technology.

Severn Trent Services, with global headquarters in Fort Washington, Pa., USA, is a leading supplier of water and wastewater solutions.
