Abstract
A method for using foam fractionation to remove a PFAS contaminant from a water source is disclosed herein. The method includes providing a feed stream to an inlet of an active column, where the feed stream comprises the PFAS contaminant and water; introducing the feed stream into an interior of the active column; flowing gas through an active column into the interior of the active column; rising gas through the feed stream in the interior of the active column to form gas bubbles in the feed stream; forming a foam layer; passing the purified stream into a next column; continuously perform foam fractionation until the feed stream becomes a cleaned stream; collecting the foam layer; and disposing of the foam layer.
