Sand filters at the two SRP separations plants have operated well for over twenty years, displaying steadily increasing efficiency for removal of activity. Pressure drop remained low on one filter although some sand was removed from the other to counteract rising pressure drop due to salts in the bed. Activity is not migrating through the beds and such breakthrough does not appear to be a life-limiting phenomenon. The underbed supports and air distribution systems were weakened by acid attack and erosion, with localized failure, prompting construction of new filters. Design studies and tests defined relations between sand characteristics, airflow resistance, and filtration efficiency. Appropriate sands were selected and monitored during construction to ensure that the new filters would have satisfactory efficiency, airflow, and pressure drop at startup.
