PFAS treatment has become a major crisis-driven innovation story in water. Utilities and industries initially turned to established technologies such as granular activated carbon, ion exchange resins, and membrane filtration because they are proven, financeable, and familiar to regulators. However, these solutions do not eliminate PFAS; they transfer it into concentrated residual waste.

This residuals problem is now driving the next phase of innovation. Emerging approaches, including foam fractionation, alternative adsorbents, advanced membranes, thermal concentration, and hybrid systems, aim to reduce waste volumes and improve downstream handling. As regulations move toward near-zero PFAS limits, the real market opportunity lies in technologies that can safely destroy or permanently manage concentrated PFAS waste.
