BioLargo Engineering Is Tackling PFAS Head-On With New Treatment Technology and is Moving To Next Phase Of Groundbreaking PFAS Work
Oak Ridge, TN -- BioLargo Engineering, Science & Technologies (BLEST), today announced that it has validated the efficacy of a new, cutting-edge water treatment technology aimed at solving the growing international per- and polyfluoroalkyl substances (PFAS) contamination crisis. Having completed its work under a Phase I SBIR grant from the EPA to its parent corporation BioLargo, Inc. (OTCQB:BLGO), it is moving to the next phase of development in preparation for demonstration pilots and commercialization.
The new technology, called the Aqueous Electrostatic Concentrator (AEC), has been proven capable of 99+% removal of the two most predominant PFAS compounds - PFOA and PFOS - without the need for the high-pressure systems and high electricity costs of reverse osmosis, or the high consumable costs necessary for carbon filters. BLEST reports that based on its bench-scale testing, AEC was projected to use only $0.30 of electricity to treat 1,000 gallons of water, a fraction of the cost of what is necessary to operate the competing technologies. BLEST management believes that they will further reduce electricity costs for treating potable water.
Described as 'forever chemicals' by Washington DC based environmental watchdog the Environmental Working Group, PFAS contamination is estimated to affect up to 110 million people in the United States. Numerous experts have linked PFAS to detrimental effects on human health and the environment due to their tendency to accumulate and persist in the environment and human body. On January 7, 2020, EPA Administrator Andrew Wheeler announced that 'aggressively addressing per-and polyfluoroalkyl substances (PFAS) is an active and ongoing priority for the U.S. Environmental Protection Agency.' The two common and widespread PFAS compounds addressed by the BLEST study - PFOA and PFOS - are found in common household and industrial products. Both compounds have been found in water supplies across the country, and municipalities are struggling to find a feasible and affordable solution to remove PFAS from their drinking water.
