For highly efficient, cost-effective arsenic removal treatment from drinking water, ADI's patented MEDIA G2® water treatment technology is capable of reducing arsenic levels to less than 2 ppb, even from concentrations as high as 1200 ppb. The MEDIA G2® technology has treated hundreds of millions of gallons of arsenic contaminated water with its arsenic adsorption technology. Communities around the world are turning to ADI to meet EPA and WHO guidelines. Over five percent of community water systems in the United States which serve over 10,000,000 people require treatment to meet the new limit of 10 ppb.

ADI's highly efficient, cost effective arsenic removal system consists of pressure vessels containing MEDIA G2®. Although MEDIA G2® water treatment system was developed for adsorbing arsenic, it will also remove iron, manganese, chromium, uranium and other dissolved metals.

ADI's MEDIA G2® is a natural compound, not a synthetic compound. It is produced in North America and consists of granular, calcined diatomite upon which ferric (iron) hydroxide is chemically bonded. Iron attracts the arsenic in water and binds it to the media by chemisorption.

Arsenic is a complex problem, but there's a simple solution for removing it. The SORB 33T System from Severn Trent Services is economical, simple to operate and requires virtually no labor. And SORB 33 delivers consistent, guaranteed performance. In this simple pump-and-treat adsorption system, the contaminated water passes through a robust NSF Standard 61 Approved granular ferric oxide media, Bayoxide® E33, developed exclusively for Severn Trent by Lanxess (Formerly Bayer AG). As the water passes through the media, the arsenic (As III and As V) is adsorbed and removed to a level below 5 micrograms per liter (µg/l).

The dry, crystalline Bayoxide E33 media was designed with a high capacity for arsenic, providing long operating cycles and low operating costs. The exhausted media is non-hazardous and can be sent to a landfill, passing TCLP requirements. To keep your costs even lower, the SORB 33 system requires no cleaning, no regeneration and no complex, labor-intensive steps. It wastes less than 0.1% of your water.

Severn Trent engineers the SORB 33 systems in any size, accommodating any flow rate, so the largest municipalities or the smallest village wellhead can benefit from this simple, cost-effective approach to a difficult problem. SORB 33 isn't just the simple solution. It's the proven solution. SORB 33 has been proven effective in full-scale commercial applications since 1999. For more than a decade, Severn Trent has been actively involved in developing arsenic removal solutions to address this global concern.

Severn Trent Services, based in Fort Washington, Pa., is a leading supplier of water and wastewater treatment solutions. The company's broad range of products and services is concentrated around disinfection, instrumentation, and filtration technologies, pipeline analysis, rehabilitation and repair services, contract operating services and state-of-the-art residential metering products and services.
