Abstract
Systems and methods for processing produced water containing organic compounds include a processing vessel; a filtration layer including a filtration material; and a cleaning system that provides a washing solution to the filtration material during a cleaning cycle. The filtration layer is configured such that at least a portion of produced water that enters the processing vessel during a processing cycle of the processing system passes through the filtration layer before leaving the processing vessel. The filtration material is a metal compound such as a metal hydroxide or a metal oxyhydroxide that is substantially insoluble in aqueous solution. The washing solution includes a reagent capable of reducing the metal compound to a reduced compound soluble in aqueous solution while not decomposing the organic compounds. The organic compounds such as crude oil may be recovered from the filtration layer material after the cleaning cycle, and the filtration layer may be regenerated.
