en.Wedoany.com Reported - Australian environmental engineering firm EPOC Enviro has commenced a large-scale trial of its patented Surface Active Foam Fractionation (SAFF®) technology at a wastewater treatment plant in Australia, following excellent PFAS removal results achieved at bench scale.

EPOC Enviro stated that the trial is evaluating the technology's ability to remove PFAS compounds from multiple interception points within the wastewater treatment process under operational conditions. Early testing has shown removal rates exceeding 97% for total PFAS compounds in the liquid wastewater treatment stage and over 80% for biosolids, with removal rates for certain C6 PFAS chemicals surpassing 99%.

The SAFF PFAS wastewater treatment trial is now in its third month at a confidential location in Australia. EPOC Enviro indicated that the project aims to address what it describes as a significant global gap in PFAS pollution control—where contaminants can enter waterways or agricultural land through biosolid reuse after passing through conventional treatment processes. Early operational data from the field trial indicates that its removal performance has already exceeded the regulatory requirements of Australia's NEPM 3.0 for PFAS remediation.

PFAS compounds, often referred to as "forever chemicals" due to their persistence and mobility in the environment, are increasingly becoming a major challenge for wastewater utilities globally. Many wastewater treatment plants were not originally designed to remove PFAS compounds, raising concerns about pollutant discharge into rivers, soil, and agricultural systems. Utilities in multiple regions are currently evaluating advanced treatment technologies capable of addressing PFAS in both liquid waste streams and biosolids.

EPOC Enviro stated that following the Australian trial, the company is preparing for more full-scale wastewater treatment deployments in the United States and Europe. The SAFF technology utilizes the principle of foam fractionation, leveraging the hydrophilic and hydrophobic properties of PFAS molecules to achieve contaminant separation through rising air bubbles and concentrated foam removal. The company says that since its launch in 2018, SAFF® technology has treated over 1.8 billion liters of PFAS-impacted water, including landfill leachate, industrial wastewater, groundwater, and reverse osmosis concentrate. The technology was developed using principles of sustainable engineering and green chemistry to support long-term environmental remediation strategies.
