The presentation will review current PFAS water treatment projects from identification and treatment to ultimate disposal of spent media. Treating very high concentration PFAS waste streams reveals important characteristics of the materials that be applied to lower concentration treatment projects. The presentation will review the stages of the projects and the considerations that are of importance at each stage.
