Audio for "PFAS Sorption Based Technologies for Separation & Concentration of PFAS from Water," Apr 7, 2026

Removal of PFAS from water has become an important concern for water utilities; landfill operators; industry professionals; and state, local, and tribal decision makers. Sorption-based technologies, specifically granular activated carbon, ion exchange resins, and foam fractionation have proven to be effective solutions in this area, but choosing the most suitable sorption-based method or system configuration can be daunting. To aid treatment practitioners, the ITRC PFAS team published a technical guidance document titled "Sorption-based Technologies for Separation and Concentration of PFAS from Water" (Section 18 of PFAS-1). This training module is intended to assist in using the information presented in this document by providing an overview of the central topics along with easily digestible summaries of critical information. This training will be crafted for an audience with some basic understanding of PFAS and that has likely already attended the PFAS 101 training and the ITRC PFAS Beyond the Basics: Fate and Transport, Site Characterization, and Source ID training. Resources and further details for the topics included in this training are available in the ITRC PFAS-1 guidance document, specifically in Sections 12 and 18. Learning objectives:Review operating principles of sorption-based technologies.Understand how site conditions and treatment objectives influence technology selection.Become familiar with testing methods (from foamability tests to isotherm tests to full-scale demonstration tests) used to verify treatment effectiveness, optimize performance, and compare technologies. Identify water quality parameters that may adversely affect sorption-based technologies and the available pretreatment methods to address themLearn how test data can be combined with cost and sustainability information to select a specific technology or system configuration.
