Per- and Polyfluoroalkyl Substances in Advanced Treatment for Potable Reuse

摘要

The frenzied regulatory activity on PFAS is necessitating a hard look at the fate of these compounds in all areas of water and wastewater treatment. Certainly, treatment designed specifically for the removal of PFAS will be necessary in many cases of drinking water contamination. However, for potable reuse projects, the crisis is less acute: In many cases, concentrations in conventional recycled water will already be less than regulatory limits for drinking, and where they are not, AWT processes already in place in typical potable reuse projects (such as RO or GAC) will address them adequately with no additional measures needed to specifically address PFAS.
