On September 30, 2025, BioLargo, Inc. (OTCQX:BLGO) announced that its proprietary Aqueous Electrostatic Concentration (AEC) technology removed more than 99 % of ultrashort‑chain per‑ and polyfluoroalkyl substances (PFAS) in a recent demonstration, including the highly mobile trifluoroacetic acid (TFA). The announcement was made by the company’s press office and published by Access Newswire on the same day.
The AEC process selectively captures and concentrates PFAS from contaminated water, and the new data show it can achieve over 99 % removal of TFA, a compound that is difficult to eliminate with conventional carbon filtration or ion‑exchange methods. The demonstration confirms the technology’s ability to address the full spectrum of PFAS, from long‑chain to ultrashort‑chain species, and validates its claim of superior removal efficiency for the most challenging contaminants.
This breakthrough positions BioLargo to accelerate commercial deployment of its PFAS remediation solution, potentially expanding its customer base among municipalities, industrial facilities, and environmental remediation firms. By demonstrating the ability to remove TFA at high efficiency, the company strengthens its competitive advantage in a market where regulatory agencies are tightening limits on ultrashort‑chain PFAS, thereby opening new revenue opportunities for the AEC platform.
