Abstract
A system for filtering organic molecules from an electrolyte solution, including a feed inlet line adapted to carry a solution with organic molecules, a filter vessel secured to the inlet line, and a pump adapted to introduce dissolved air into the solution in the feed inlet line. The filter vessel is a solvent extraction filter having coalescing media above a solution outlet at the bottom of the vessel and an organic vent outlet at the top of the vessel. The system operates by (a) dissolving air into the solution, (b) inputting the solution with dissolved air into the filter vessel, (c) outletting solution from the bottom vessel outlet to flow solution down through coalescing media, and (d) periodically venting floating organic molecules from the top of the vessel.
