Glendale, Arizona selects Calgon Carbon reactivation services

Calgon Carbon has been awarded a ten-year contract by the city of Glendale for reactivation services for activated carbon used to treat the city’s drinking water.

The value of the contract will depend on the amount of spent carbon that is reactivated annually, which is expected to be around 1.25 million pounds.

Glendale is using granular activated carbon (GAC) as per the US Environmental Protection Agency (EPA’s) Stage 2 Disinfectants and Disinfection Byproducts Rule. The rule establishes maximum levels at which disinfection by-products are permitted to be present in drinking water.

It is the third ten-year reactivation services contract that the company has secured in Arizona since the beginning of 2012. To support these contracts, the company constructed a new reactivation facility in Gila Bend, Arizona in April with an annual reactivation capacity of approximately 25 million pounds.

Calgon Carbon executive vice president and chief operating officer Bob O’Brien said that the contract affirms Glendale’s commitment to the use of GAC as its primary means of complying with the EPA’s disinfection byproducts regulations.

"The city has been using reactivated carbon for a number of years, and their willingness to enter into a long-term contract demonstrates their belief in the economic and environmental benefits of reactivated GAC for drinking water treatment," O’Brien added.

Glendale, Arizona, located on the west side of the Phoenix metropolitan area, is a community of around 226,000 residents, with over 62,000 water customers.
