Abstract: An installation for the treatment of solutions by solid ion exchangers in a mobile bed, comprising an initial chamber formed by a central cylindrical column, followed by an even number of successive concentric annular chambers surrounding at least part of the central column, the exchange media rising up through the said column, spilling over the whole periphery of its top edge down into the first annular chamber, and passing from the bottom of the latter to the bottom of the second annular chamber. The flow of liquid in the column and the two chambers occurs in directions opposite to the directions of movement of the bed therethrough and whenever two liquids of different densities are present in the same chamber, the denser liquid is below the lighter liquid and is separated therefrom by an interface. The inlet and outlet flow rates of each liquid are controlled to keep the movements of an interface between certain limits during the operation of the installation.

Abstract: In the closed cycle, mobile bed, liquid-solid treatment installation disclosed herein, a given volume of the solid material is periodically displaced in the treatment chamber by a given volume of liquid under a given pressure. The solid material is advanced in the cycle through two columns which are separated from each other by at least one intermediate receiver that is located between two isolation valves through which the solid material passes without being crushed, and that receives from one of the columns a constant volume constituted of one or more batches of said given volume of solid material.

Abstract: A single column contains a moving ion-exchange bed in which the treatments of regeneration, washing and exhaustion are effected simultaneously in three different vertical sections of the column. The successive batches of exchange resins are fed into the bottom of the column so as to bring about the intermittent progression of the bed, and each successive batch of resins is recovered at the top of the column. The rates of flow of the purified liquid, the regenerant flow and the discharged effluent are controlled so that the raw liquid inflow rate automatically adjusts itself to assure that an adequate flow distribution will be maintained in the different sections of the column.

Abstract: 1,156,749. Ion-exchange. COMMISSARIAT A L'ENERGIE ATOMIQUE and SOC. GRENOBLOISE D'ETUDES & D'APPLI-CATIONS (HYDRAULIQUES SOGREAH. 18 May, 1967 [20 May, 1966], No. 23203/67. Heading B1J. Liquids to be treated by ion-exchange are admitted to a bed at 2 and are discharged from the sand embedded strainer 3. At the end of a period of treatment an injection of driving fluid at 11 forces the exchange up the column discharging solid at 12 and fluid at 14. The column is replenished from reservoir 9 and when the removal of resin stops a suitable state of equilibrium is reached in the chamber 8. The process of treatment is then repeated.
