PFAS REMOVAL

Harnessing Nuclear Science
for PFAS Removal

Per- and polyfluoroalkyl substances (PFAS) are valued for their remarkable properties, including heat resistance, water repellency, oil repellency, and electrical insulation. These characteristics have made them indispensable in everyday products as well as critical industrial applications. However, PFAS are often referred to as “forever chemicals” because of their persistence in the environment and their tendency to bioaccumulate. Growing evidence of health risks, including carcinogenicity, has turned PFAS pollution into a global concern, lending to increasingly stringent regulations. Conventional treatment technologies such as activated carbon and membrane separation struggle to completely remove the wide variety of PFAS contained in high concentrations in wastewater. As a result, PFAS continue to accumulate and spread to result in contamination. To address this urgent challenge, Emulsion Flow Technologies provides an innovative solution based on our proprietary Emulsion Flow solvent-extraction technology.

TECHNOLOGY

Unique Features of Emulsion Flow

Capable of treating wastewater containing PFAS across a wide range of concentration range from ppt to ppm.
Recovers over 99.9% of diverse PFAS, from short-chain to long-chain.
Robust operation, unaffected by coexisting substances.
10,000-fold concentration dramatically reduces residual waste volume.
Exceptional selectively enables synergy with photodegradation technologies and other technologies.
High extraction efficiency, as the volume of the oil phase itself serves as the reaction space.

PFAS Removal Performance
This figure demonstrates removal rates for various PFAS compounds from short to long-chain per treatment cycle. By repeating the process, EFT’s technology achieves removal efficiencies exceeding 99% reducing PFAS concentrations below the water quality standard of 50 ppt, which will be enforced April 2026.

PFAS REMOVAL PROCESS

EFT’s Emulsion Flow process is capable of treating wastewater containing PFAS ranging from trace ppt levels to ppm levels, ensuring cost-effective and high-efficiency separation and removal of both short- and long-chain PFAS. Moreover, its unrivaled concentration capability enables selective separation and ultra-concentration exceeding 10,000-fold. This minimized the volume of the waste liquid. This significantly lowers the thermal energy and CO₂ emissions required for incineration. The concentrated PFAS stream can also enhance the performance of PFAS degradation technologies into advanced treatment systems Ultimately, EFTs approach aims not only eliminating PFAS contamination but also realizing “PFAS-free factory systems” addressing industrial pollutions contributing to sustainable water management and a circular society.
