Abstract: A process for the partial desalination of water with a combination of weakly acid cation exchangers in free acid form and basic anion exchangers in hydrogen carbonate form, both present in aqueous suspensions, and subsequent regeneration of the charged ion exchanger material. The partial desalination is effected with a combination or mixture of a weakly acid cation exchanger material and a basic anion exchanger material. Depending on the combination or mixing ratio of the two exchangers, non-equivalent quantities of neutral salt cations and anions are removed from the water. The regeneration of both exchangers together is effected exclusively with the aid of CO.sub.2.

Abstract: The present invention relates to a process and an apparatus for continuously extracting ions from a clear liquid or a liquid containing materials in suspension, by means of a bed of grains of exchange substances.The process comprises maintaining the bed in a permanent condition of fluidization by an absolutely continuous feed of liquid, and subjecting the bed to cyclic pulsation phenomena in such a way as to ensure grading of the grains on the basis of density, in dependence on their ion charge. To carry out that process, an apparatus comprises a fluidization column which does not have any plate capable of interfering with the grading operation, a pulsation generator which operates by taking off liquid at the top of the column and re-injecting it in a surge manner at the base of the bed, and a system for centrifuging the liquid to be treated, for removing the sandy materials therefrom.This process and apparatus are used when there is a wish to extract any type of anions or cations or exchangeable salts, in an absolutely continuous mode of operation, from clear liquids or liquids containing materials in suspension, by means of mineral exchange substances or resins, to avoid the problems of clogging and abrasion, and to achieve the maximum extraction capacity and rate.

Abstract: The invention relates to an apparatus for treatment of particulate mixtures such as a mixture of solid particles, which is to be depleted in, enriched by or treated with a fluid, or wherein the mixture acts as a treatment medium for a fluid passing through same. The apparatus is of the type operating with an advancing bed of the particulate material. It utilizes walls permeable by at least a portion of the fluid. The apparatus is of the type of tubular, rectangular or the like vessel having only stationary parts and subdivided by a selected combination of permeable and non-permeable walls into separate chambers into or from which the fluid can be delivered or removed. The movement of the particulate mixture is effected solely by forcing same through a passage having preferably but not exclusively an annular chamber, by pumping, by gravity or by a combination of both. Additional throttling or valve means are employed to selectively control the advancement of the bed through the device. The device is simple in structure and can be relatively easily adjusted for a great variety of different operations, from plain filtering to a complex washing or treatment of the particulate bed with different liquids in order to extract desired matter from the raw bed.

Abstract: Process for producing fully desalted process water by the treatment of raw water with cation and anion exchangers in a separate multi-stage arrangement. The water which leaves the main cation exchanger stage or stages, has a residual sodium content of less than 0.5 mg Na/l before entering the anion exchange stage. Such water is fed through a strong acid cation exchanger stage, in which the exchanger material is present at a maximum of 50 percent as a suspended bed and the remainder as a solid bed. The exchanger material in the strong acid cation exchanger stage following the first strong acid cation exchanger stage, is present at a maximum of 25 percent as a suspended bed and the remainder as a solid bed.

Abstract: A process for absorbing ions of interest onto ion exchange resin particles from a feed liquor containing ions which when absorbed on said particles cause the density of the particles to increase. The process comprises the steps of(1) flowing the feed liquor upwardly through a main bed of ion exchange resin particles contained in a main chamber of an absorption column and thereby maintaining the bed in fluidized state;(2) continuously collecting the denser loaded particles from the lower region of the absorption column;(3) passing an outflow of the feed liquor from the upper region of the main chamber upwardly into the lower region of the polishing chamber containing a secondary bed of fluidized ion exchange resin particles whereby residual ions of interest are polished from the liquor, and(4) producing a barren liquor flowing out of the upper region of the polishing chamber.

Abstract: A flow distributor for a fluid bed reactor includes means for decreasing velocity of incoming liquid streams in a uniform, non-turbulent fashion. Inlet ports communicate with fluid portals having divergent walls to slow incoming flow. The fluid portals feed liquid flow to a plurality of diffusing flow paths provided between diffusion baffles positioned at the bottom of the reactor. The diffusion baffles may be prismatic shapes which are trapezoidal in cross-section with the broadest horizontal dimension at the bottom thereof. The diffusion flow paths therefore have divergent walls and act to further slow the liquid flow passing therethrough.
