What is PFAS in Sludge? (With Veolia) | WWD Weekly Digest

Per- and polyflouroalkyl substances (PFAS) detection and treatment are a major focal point of the U.S. EPA, particularly as it relates to wastewater treatment. Through the wastewater process, PFAS can be found in sludge, meaning utilities will likely need to treat it with regulations the U.S. EPA is promulgating currently.

Sudhakar Viswanathan, National Sales Manger for biosolids and bio energy for Veolia Water Technologies and Jon Orr, Product Manager for biosolids and bio energy for Veolia Water Technologies, explain the technology that is available for treating PFAS in sludge and how it can also address other contaminants of emerging concern.
