BioLargo demonstrates over 99% removal of ultrashort-chain PFAS

BioLargo (BLGO) announced new evidence that its proprietary Aqueous Electrostatic Concentration PFAS solution achieves over 99% removal of ultrashort-chain per- and polyfluoroalkyl substances, including trifluoroacetic acid, a notoriously persistent and mobile contaminant which means it can move easily through the environment. TFA is difficult to remove and destroy because it has only two fluorinated carbon atoms making it resistant to typical environmental breakdown. It is often found in solvents and reagents used by industry, and is a common byproduct of many industrial processes. A study published in Environmental Science & Technology demonstrated that TFA accounted for more than 90% of the total PFAS mass in various drinking water sources in Germany. This breakthrough marks a significant milestone in the fight against PFAS pollution, particularly for compounds like TFA that have eluded conventional treatment methods due to their small molecular size and high solubility. The company’s internal testing, conducted in collaboration with third-party laboratories, confirms that AEC consistently removes TFA and other ultra-short chain PFAS at rates exceeding 99%, without generating harmful byproducts or secondary waste streams. These results build on BioLargo’s previously validated performance with long-chain PFAS such as PFOA and PFOS. The BioLargo solution allows for the efficient removal and concentrated collection process of PFAS, which is then followed by a propriety destruction technique.
