Field Well Water - PFAS Removal By AEC 3-Cell Unit

BioLargo’s Aqueous Electrostatic Concentrator (AEC) was used to treat well water provided by a major water district in Southern California with the aim of determining the removal rate for the 25 different per- or polyfluoroalkyl substances (PFAS) covered by EPA Method 533. Water was run through the AEC five times.  Samples were submitted for analysis from the first pass (1^st Turnover), the third pass (3^rd Turnover), and the fifth pass (5^th Turnover). The AEC system was shown to reduce the concentration of the 11 different PFAS compounds found in the source water to below their limit of quantification (LOQ) by the 3^rd Turnover. The other 14 PFAS compounds could not be detected in the untreated well water.
