Abstract
A system and method for foam fractionation with gas recycling is disclosed herein. The method includes using foam fractionation to remove a contaminant from an aqueous source. The method includes providing a feed stream to an inlet of an active column; 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; extracting the foam layer; passing the foam layer through a liquid-gas separator to obtain a recycle gas stream; feeding the recycle gas stream to a recycling device; and re-introducing the recycle gas stream to the active column using the recycling device.
