US 2013/0153473 A1 · CONCENTRATE TREATMENT SYSTEM

Abstract

In one aspect the invention provides a system for treating a wastestream, particularly a radwaste, for safe disposal and, in final processing converting it into one or both forms including an aqueous form for safe discharge to the environment and a solidified form for safe disposal. In another aspect the invention provides the capacity to employ a step where a specific target element strategy can be set up synchronizing sorbent substance choices and multiple recycle options to remove target substances from wastestream as a part of its Sorption or Powder Sorbent Isotopic Reduction step (II). Other steps cooperate with Sorption step (II) including Oxidation (I), Solid-Liquid separation (III), and Selective Ion Exchange (IV) to deliver the wastestream to final processing.

Dependent claims

A system for treating a 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 it 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;
(II) mixing the wastestream with 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.
