BioLargo’s PFAS Removal System Achieves Total Elimination of Multiple PFAS Compounds in Testing with Client Water

BioLargo, Inc. press release

BioLargo, Inc., a developer of sustainable cleantech technologies and full-service environmental engineering company, announced that its Aqueous Electrostatic Concentrator (AEC) has been proven to eliminate multiple per- and polyfluoroalkyl substance (PFAS) compounds from water provided by a large municipality in Southern California. 

Found in water all over the world, PFAS are a group of chemicals generated by industrial operations that have been linked to adverse health effects. They are subject to escalating regulatory action by the Biden Administration and the EPA due to their inability to break down naturally in the environment and their impacts on human health. Also known as “forever chemicals,” PFAS have been linked to cancer, developmental delays, hormone disorders, and more. According to Washington DC based Environmental Working Group, PFAS has been founding in water in over 2,800 locations in the U.S. 

Previously, the company reported that the AEC had been shown to reduce the levels of several PFAS compounds present in water provided by the prospective municipal client to below State and Federal standards. These new results prove that the AEC has removed multiple PFAS compounds to below the limit of quantification (i.e., functionally eliminated) following optimization of the AEC’s membranes and contact time.

“These results confirm not only that the AEC can deliver virtually total elimination of PFAS from contaminated drinking water, but that the technology can, with relative ease, be fine-tuned to achieve varying levels of treatment performance as prescribed by a client’s own treatment goals and regulatory needs," said Randall Moore, president of BioLargo Engineering, Science & Technologies.

“These results show that the AEC is an effective solution for customers seeking PFAS water treatment and removal, and will be integral as we advance to commercial trials and first sales of the technology," said Tonya Chandler, director of Strategic Marketing and Business Development at BioLargo. "Our AEC system is capable of total PFAS elimination while generating less than 1/1000 the volume of PFAS-laden waste product compared to carbon filtration, the most common solution in the market today. No one wants to trade one environmental disaster for another, and the AEC helps avoid the trailing environmental impact and significant cost associated with disposal of PFAS-laden carbon.”
