PFAS Removal System Proven Effective In Removing Both Long And Short Chain PFAS

A small Wisconsin municipality faced a significant challenge with their drinking water, which was contaminated with nine different per- and polyfluoroalkyl substances (PFAS). Traditional treatment methods, such as carbon filtration and ion exchange, were not well-suited for this problem due to the water's high chloride content and the presence of both long- and short-chain PFAS. An additional concern with these methods was the large amount of contaminated solid waste they generate.

As an alternative, the municipality tested a new technology, the Aqueous Electrostatic Concentrator (AEC). In a single pass, this system successfully reduced all nine PFAS compounds to "non-detect" levels. A key advantage of the AEC is its ability to treat both long- and short-chain PFAS while generating minimal PFAS-laden waste. The technology's efficacy, flexibility, and low operating costs demonstrate its potential as a commercially viable solution for municipalities seeking to address PFAS contamination.
