Dewatering equipment recommendations for the solids/liquid separation project at Waste Area Grouping 6 at Oak Ridge National Laboratory, Oak Ridge, Tennessee. Environmental Restoration Program

摘要

The final closure of Waste Area Grouping (WAG) 6 at Oak Ridge National Laboratory will include the plugging and abandonment of many existing wells and boreholes and the installation of diversion trenches for groundwater control. These activities will generate soil that must be dewatered before it can be disposed of. Three different types of dewatering equipment(emdash)rotary vacuum drum filters, automatic discharge pressure filters, and centrifuges(emdash)have been evaluated to assess their suitability for the WAG 6 project. Because of its lower cost and minimal prescreening requirements, it is recommended that a centrifuge be used to dewater the WAG 6 soils.
