PFAS Destructive Treatment Methods: Case Studies and a Commercial Application Review
Tuesday, December 5, 1:00 pm – 2:30 pm ET (rescheduled from Monday, November 13)

In the PFAS destructive treatment space, there is a generally accepted paradigm that separation and concentration are key to efficient and economic PFAS destruction. Less accepted and understood are which concentration and destruction technologies pair well together. Available aqueous separation and concentration strategies – including non-regenerable and regenerable media treatment, foam fractionation, and membrane filtration - generate wastes or residuals with unique and specific chemical characteristics. A limited number of available PFAS destruction technologies are applicable to treating PFAS in biosolids and efficient pairings depend in part on how the treatment plant currently processes their biosolids. This webinar will present case studies that treated waste residuals from regenerable ion exchange media treatment, foam fractionation, and biosolids with multiple types of PFAS destruction technologies. Combined solutions will be evaluated on the basis of compatibility, efficiency, complete destruction of PFAS, and overall cost.
 
Supercritical water oxidation (SCWO) uses high temperature and pressure to destroy PFAS in contaminated wastewater, landfill leachate, and Aqueous Film Forming Foam (AFFF) to non-detectable levels with PFAS-free water remaining. Revive Environmental’s PFAS Annihilator™ is the first PFAS destruction solution to be fully permitted and deployed commercially in North America. Using SCWO, the PFAS Annihilator destroys PFAS in landfill leachate – treating the hyper-concentrate resulting from foam fractionation treatment of raw leachate and industrial wastewater. In addition, the treatment unit is being utilized to destroy AFFF concentrate and rinsate from foam transition projects. 
 
The webinar will address the following topics/objectives:

  • Identify the tradeoffs between different aqueous concentrating treatment technologies
  • Understand the basic operating conditions of different PFAS destruction technologies and their ability to treat a range of PFAS
  • Understand how water quality characteristics impact destructive technologies
  • Understand which destructive technologies are and aren’t applicable to biosolids
  • Understanding of the capabilities and commercial readiness of SCWO in treating different PFAS-contaminated aqueous matrices
  • Lessons learned in working with state and municipal regulatory partners to evaluate the air, waste, and water emissions fully
  • Lessons learned in the first commercial deployment, commissioning, and ongoing operation and optimization of the PFAS Annihilator ™

Dr. Erika Houtz, Director, Contaminant Destruction, ECT2
Dr. Houtz is the director of contaminant destruction at ECT2. At ECT2, she is engaged in the evaluation and development of treatment and destruction technologies that can be incorporated into ECT2 treatment systems. She has extensive experience in developing analytical and experimental methods for the measurement and breakdown of anthropogenic compounds in environmental and human samples, including developing the total oxidizable precursor (TOP) assay for measurement of PFAS. She has authored or co-authored more than ten peer reviewed publications. Erika earned her PhD and MS degrees in environmental engineering from the University of California, Berkeley, and her BS in chemical engineering from Ohio State.
