Webinar | 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 reinstates, 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.
