The value of the contract will depend on the amount of spent carbon that is reactivated annually, which is expected to be 1 million pounds.
California’s Palmdale Water District is using granular activated carbon (GAC) to meet the US Environmental Protection Agency’s Stage 2 Disinfectants and Disinfection Byproducts Rule, which establishes maximum levels at which disinfection byproducts are permitted to be present in drinking water.
The GAC removes organic compounds from the water, reducing the formation of byproducts that occur with the addition of chlorine.
The Palmdale Water District will be converting to Calgon Carbon’s high performance Filtrasorb400 GAC, which when spent, will be taken to the company’s facility in Gila Bend, Arizona for custom reactivation.
