Abstract

An apparatus is provided for treating various radioactive concentrates having a liquid component, such as suspensions and salt solutions, which are present separately in a processing plant from evaporation systems, resin bead ion exchange filters, and from at least one further separating stage provided with, for example, mechanical filters, sedimentation basins and/or powdered resin ion exchange filters. The filter concentrates containing suspended solids are dewatered in a filter cake-producing filter and the concentrates from the evaporation system (salt solutions) are dewatered wholly or in part directly in transporting and storage drums to the dryness required for storage. At least one of the various concentrates are at least for a time conducted directly (without dewatering) into a storage drum where they are mixed with binders and converted to solids by hardening.
