We supply specialist grades of granulated activated carbon (GAC) for PFAS removal from waste water and site fire fighting facilities that have been used with, or have become contaminated, with PFOS and PFOA fire fighting foam.
PFAS is a large family of manmade chemicals which have been used in many different types of manufacturing since the 1940s, and in foams since the 1960s.
- PFOS (perfluorooctane sulfonic acid) and PFOA (perfluorooctanoic acid) are members of the PFAS family of chemicals.
- Importing and manufacturing fire-fighting foams containing PFOS or PFOA was effectively prohibited in New Zealand in 2006 (under the Fire-Fighting Chemicals Group Standard).
GAC - Granulated Carbon Use
The granular activated carbon is used in a fixed bed filter system. A two filter vessel lead/lag configuration is often applied to enable continuous operation during GAC change out and/or to ensure against any breakthrough.
Acticarb GS1300 has been proven to remove PFAS down to non-detectable levels.
