Abstract: Provided is a system and method for extracting organic solutes from water with a filter media. The system and method allow for regenerating the filter media following treatment of a water supply containing one or more organic solutes to allow the media to be reused for subsequent water treatment operations. The system and method also allows for regeneration of the displacement fluid for reuse in the regeneration of the media with recovery of at least one or more organic solutes from the displacement fluid. Additionally, the system and method allows for substantially continuous treatment of a water supply and regeneration of a filter media.
