Ion Exchange Processes for Clean-Up of Dilute Waste Streams by the F/H Effluent Treatment Facility at the Savannah River Plant

摘要

The F/H Effluent Treatment Facility will treat dilute waste streams currently diverted to seepage basins at the Savannah River Plant. In November 1988, the seepage basins are scheduled to be retired and the facility will process the streams to remove toxic and radioactive species before they reach the environment. After rigorous filtration and reverse osmosis, cation exchange will be used as a polishing step. Mercury and other non-radioactive heavy metals will be removed on a thiol cation exchange resin that will not be removed using a sulfonic acid resin that will be regenerated. The spent thiol resin will be stored and the solution containing recovered cesium and strontium will be incorporated in concrete for disposal. (ERA citation 12:020105)
