Battle developed a closed-loop on-site platform designed to destroy per- and polyfluoroalkyl substances or “eternal chemicals” in contaminated water and conducted a pilot demonstration technology in early March at a wastewater treatment facility operated by Legacy-Crystal Clean in Michigan.
the Battelle Mobile Unit PFAS Annihilator can break down PFAS chemicals to undetectable levels in contaminated water using the process of supercritical water oxidation, the nonprofit research and development company said in an April 27 press release.
“In this pilot project, we saw the Battelle PFAS Annihilator demonstrate its ability to reduce total PFAS in landfill leachate to single digit concentrations without undesirable by-products in the treated water,” said Amy DindalPFAS program manager at Battelle.
PFAS chemicals are used in stain-resistant textiles, nonstick cookware, food packaging, paint, and other industrial and consumer products, but are able to withstand water, heat, grease and oil, making them difficult to remove from the environment.
“We have successfully demonstrated that this technology can be brought to a facility that processes waste, sets up in hours, and destroys PFAS chemicals in the presence of other co-contaminants,” Dindal added.
Battelle is building the next iteration of the mobile unit that can destroy PFAS chemicals in industrial-sized sewage containers.
