The U.S. Patent and Trademark Office recently issued Pittsburgh-based Calgon Carbon Corp., a purification solutions company, with a patent for the removal of PFAS from a liquid or gas using reactivated carbon.
“We are thrilled to announce this latest addition to our intellectual property portfolio,” Jenalle Brewer, Calgon Carbon senior vice president of drinking water solutions and global business development, said. “This patent not only recognizes our team’s commitment to scientific innovation but also reinforces our leadership in providing high performing, reliable, and sustainable solutions to Americans in communities large and small. Our domestically produced advanced sorbent technology gives our customers an advantage on cost, performance, and reliability and is a key component in our mission to help ensure clean water for all.”
PFAS are synthetic compounds used in industrial and consumer products that pose environment and potential health risks. Calgon Carbon’s system captures and destroys PFAS contamination. The recovered activated carbon is returned to continued use. It is used for removing PFAS from drinking water and wastewater.
Calgon Carbon employs approximately 1,800 people and operates 20 manufacturing, reactivation, innovation and equipment fabrication facilities in three countries. It is a wholly-owned subsidiary of Kuraray Co., a manufacturer and distributor of coal-, wood- and coconut-based activated carbon products.
