Under the agreement, Calgon Carbon will build a reactivation facility in Maricopa County, Arizona, which will be used to reactivate Phoenix’s spent carbon.
The value of the contract will depend upon the amount of spent activated carbon that is reactivated annually, which is expected to be about 11 million pounds.
It will be owned and operated by Calgon Carbon and will have an annual reactivation capacity of about 25 million pounds.
The reactivation facility is expected to be completed in the next year.
The facility is expected to provide custom reactivation services for other municipalities that utilize granular activated carbon (GAC) to treat their drinking water, including two additional cities in Arizona.
The GAC removes organic compounds from the water, reducing the formation of byproducts after the addition of chlorine.
Calgon Carbon executive vice president and chief operating officer Bob O’Brien said since reactivated carbon is less costly than virgin carbon and the reactivation process produces far less CO2 than the virgin carbon manufacturing process, the city will also realize significant economic and environmental benefits.
US-based Calgon Carbon is engaged in services and solutions for making water and air safer and cleaner.
