Abstract
A method is disclosed for treating liquid radioactive waste to provide reusable water, while reducing the overall volume and water content of the removed solid contaminants. The process is carried out in two separate stages, generally in at least two separate locations. In the first stage, the waste is pretreated at a first site, preferably where the waste was generated, to provide clean water, and a concentrated fraction containing removed suspended and dissolved solids, as well as some remaining water. The pretreatment typically involves passing the liquid waste through one or more microfilters, ultrafilter or nanofilters in combination with a reverse osmosis membrane. In the second stage of the process, the concentrated waste fraction, containing the removed solids, is transported to a second site, where it is thermally treated to remove the remaining water and reduce the volume of the remaining solids.
