BioLargo announces upgrade to Aqueous Electrostatic Concentrator system

BioLargo (BLGO) announced a breakthrough upgrade to its patented Aqueous Electrostatic Concentrator (AEC)system-cutting the AEC’s energy use by more than 90% in large-scale PFAS treatment for drinking water as compared with the prior generations of the AEC. These savings are on top of data reported in May 2025 that an AEC system can offer up to 80% total-life cycle cost savings over competing technologies like carbon, due to AEC’s efficiency for its collection of PFAS molecules and ease of handling the PFAS-laden by-products of the operation. This new energy reduction breakthrough adds to the already compelling economic argument in favor of the AEC over incumbent technologies, resulting in an industry-leading combination of cost efficiency, energy performance, and non-detect PFAS removal (below 1 part per trillion) in both drinking water and brackish sources.
