Approximately 6 million pounds of spent activated carbon is expected to be reactivated annually.
 
Scottsdale is using granular activated carbon (GAC) to comply with the US Environmental Protection Agency’s (EPA) disinfection byproducts regulations. The GAC removes organic compounds from the water, reducing the formation of byproducts after the addition of chlorine.
 
This is the second ten-year reactivation services contract that Calgon Carbon has secured in Arizona this year. In March, the company signed a ten-year contract with the city of Phoenix, Arizona.
 
Calgon Carbon is currently constructing a reactivation facility in Gila Bend, Arizona, which is expected to be completed in 2013. The new facility will have an annual reactivation capacity of approximately 25 million pounds.
