Waste treatment advances: lime treatment and ammonia recovery of liquid waste

In the conversion of UF/sub 6/ to UO/sub 2/ by the ammonium diuranate process, a primary waste stream is nonradioactive ammonium fluoride in aqueous solution with excess free ammonia. To overcome the problems generated by the poor settling qualities of the liquid effluent and the difficulty in controlling its pH, two design revisions were made in the waste processing. The first was replacement of the settler-filter system with a large settling lagoon to assure proper solids separation. The second revision was the installation of a combined lime treatment with ammonia recovery by distillation and steam stripping. (JSR)
