Management Of PFAS And Other Emerging Contaminants Using Catalyzed UV Technology
Background/Objectives
Per- and polyfluoroalkyl substances (PFAS) remain difficult to manage because conventional
treatment often concentrates rather than destroys contamination. Catalyzed UV technology
was developed to provide destructive treatment, using UV-activated photocatalysis and
photoreactor design to convert PFAS-associated organic fluorine to inorganic fluoride. This
webinar highlights progress from bench-scale chemistry toward scalable treatment trains for
PFAS and other emerging organic contaminants in real-world matrices.
Approach/Activities
Photoreactor geometry and chemistry have been optimized, and Catalyzed UV technology
has advanced from benchtop operation toward a 10 liter per hour floor-scale system. Testing
evaluated PFAS destruction across compound classes, pH conditions, inorganic and organic
co-contaminants, industrial wastewater, aqueous film-forming foam rinsates, and PFAS
enriched regenerants. Sorbent concentration/regeneration and tunable oxidation/reduction
modes have also been evaluated to support practical treatment-train design.
Results/Lessons Learned
Results demonstrate broad PFAS applicability and confirm that kinetics and operating
conditions are compound- and matrix-dependent. Catalyzed UV technology has achieved
significant PFAS destruction in landfill leachate, PFAS-enriched regenerant, and complex
wastewater, as will be demonstrated by case studies. Tunable oxidizing and reducing modes
also broaden application to other emerging and legacy organic contaminants.
