Abstract: METHOD FOR REGENERATION OF ION EXCHANGERS HAVING THE SAME IONIC NATURE AND DISPOSED IN SUPERPOSED LAYERS IN THE SAME APPARATUS, SAID IONS BEING SATURATED BY CIRCULATING THE LIQUID TO BE TREATED IN DOWNWARD FLOW THROUGH THE SUPERPOSED LAYERS OF ION EXCHANGERS WHICH ARE REGENERATED BY CIRCULATING THE REGENERATION REAGENT IN COUNTERCURRENT FLOW THROUGH THE LAYERS OF ION EXCHANGERS. AT LEAST ONE REGENERATION REAGENT IS PASSED UPWARDS THROUGH THE DIFFERENT SUPERPOSED LAYERS OF ION EXCHANGERS AND AT LEAST ONE ADDITIONAL STREAM OF LIQUID IS INTRODUCED IN THE VICINITY OF THE INTERFACE BETWEEN TWO SUPERPOSED LAYERS OF ION EXCHANGERS, SAID ADDITIONAL STREAM BEING ALSO CIRCULATED UPWARDS THROUGH THE LAYER OR LAYERS OF ION EXCHANGERS TOGETHER WITH THE STREAM OF REGENERATION REAGENT.

Abstract: Improved fluidizing apparatus adapted to separate continuously ion exchange resins having different densities in order to perform their selective classification according to suitable granulometric distributions. The apparatus comprises a first separation chamber and in the lower portion of this first separation chamber a second chamber coaxially thereto having a gradually increasing cross-section from the bottom to the top.

Abstract: Treatment of water by crystalline pptn. and decantation, comprises forming a homogeneous dispersion of the water, the reactants required for the pptn. and sepd. sludge from previously treated water. The conc. of crystal nuclei is sufficient for the pptn. to be almost complete before the decantation stage and to be completed during decantation. Used for treating drinking and industrial water or aq. industrial effluent contg. chalk, lime, bicarbonate, sulphates, phosphates etc., the process enables accurate closing and distribution avoiding crusting up of walls, pipes, etc.
