KUALA LUMPUR, Dec 8 (Bernama) -- A new study by Calgon Carbon Corporation (Calgon Carbon) has provided a definitive response to a persistent question about the fate of Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) during reactivation of activated carbon.
“The single-biggest conclusion from the study is that PFAS compounds are effectively removed from spent carbon through the reactivation process, as well as showing greater than 99.99 per cent destruction of PFAS through our furnace and abatement system,” said Senior Applications Engineer at Calgon Carbon, Rebecca DiStefano.
Reactivation is a high-temperature thermal process that is commonly used by municipalities and industrial users to recycle their used activated carbon and destroy contaminants it has removed.
According to a statement, the study’s findings come at a time of growing concern and increased focus about the impact of PFAS, often referred to as “forever chemicals” because of their inability to break down over time in the environment.
Calgon Carbon’s FILTRASORB® granular activated carbon (GAC), sourced from bituminous coal, has demonstrated superior PFAS-removal capabilities compared to other carbons for two decades.
GAC is the most widely used and well-established treatment technology for the removal of PFAS contaminants from drinking water and wastewater.
For its study, Calgon Carbon enlisted the services of an independent, third-party vendor to test air samples for 36 PFAS compounds.
Another third-party vendor analysed well water and treated motive water samples for PFAS, as well as analysing samples of spent carbon, reactivated carbon, abatement dust, and bicarbonate raw material for extraction and targeted PFAS.
Headquartered in Pittsburgh, Pennsylvania, United States, Calgon Carbon – a wholly-owned subsidiary of Kuraray Co, Ltd – is a global leader in the manufacturing and distribution of innovative coal-, wood- and coconut-based activated carbon products – in granular, powdered, pelletised and cloth form.
The company provides purification solutions for more than 700 distinct applications, including drinking water, wastewater, pollution abatement, and a variety of industrial and commercial manufacturing processes.
