Patent ID: 8753518

Claim:
A system for treating a liquid or aqueous wastestream consisting of at least one of a group of wastes consisting of radioactive concentrate fluid, historic waste and other forms of environmental or hazardous waste or radwaste; and converting the wastestream into at least one of two selected forms including a form which can be solidified, or solidified form, for safe disposal and an aqueous form which can be safely discharged to the environment, said system comprising the steps, designated as Roman numerals: I, II, III, IV and V, of: (I) oxidizing the wastestream such that any existing chelant material or substance contained in the wastestream is substantially rendered non-effective as a chelant of metals or destroyed thereby releasing the metals into ionic form, and the wastestream is rendered subject to, or permissive of, precipitation of cobalt and other metals and release of other isotopes for removal; (II) mixing the wastestream with at least one target Sorbent material for Isotopic Reduction; (III) separating the wastestream into Solid and Liquid components; (IV) treating the wastestream by Selective Ion exchange (IX); and (V) final processing, wherein at least one step is chosen from a group consisting of: (Va) discharging the wastestream in said aqueous form, and (Vb) drying of a resulting wastestream having dissolved solids to Dry Solids, as said solidified form.
