Abstract

See full text

A method and apparatus is disclosed for separating an amount of a perfluoroalkyl or polyfluoroalkyl substance (PFAS) from water which is contaminated with the substance. The method comprises the steps of: admitting an amount of the water, which includes an initial concentration of the substance, into a chamber via an inlet thereinto, and introducing a flow of gas into the chamber. The introduced gas induces the water in the chamber to flow, and produces a froth layer which is formed at, and which rises above, an interface with the said flow of water and of introduced gas in the chamber. The froth layer includes an amount of water, and also a concentrated amount of the substance in comparison compared with its initial concentration. The step of removal of at least some of the froth layer from an upper portion of the chamber occurs.
