Abstract:
An apparatus for separation of chemical substances and production of sterile solutions, which comprises a column closed with plugs at the ends thereof and containing an ion-exchange agent and at least one filter. In the body of each plug there is a piercing duct with an inner expansion chamber wherein a resilient stopper is placed, which stopper is provided with longitudinal notches at its external surface extending over the end surface of the stopper facing the column so that said longitudinal notches communicate with the piercing duct of the plug. At the opposite end of the stopper there is a closing cone abutting with its surface upon the edges of the end portion of the piercing duct thus ensuring tight sealing of the latter. Each of the plugs is provided with a cover adapted to be attached to a vessel for solutions and having an inner hollow pressure rod passing through the end portion of the piercing duct of the plug and activating, by its end, the closing cone of the stopper so that upon putting the cover on the plug the stopper is compressed by the rod and the piercing duct of the plug becomes open for the flow of solutions.
Abstract:
In accordance with the invention there is provided a porous adsorbent body comprising an array of granules of adsorbent material and particles of thermoplastic organic polymer bonded to the granules with at least some of the particles bridging contiguous granules thereby bonding them together to form a self-sustaining body having interstices which open into each other for admission of fluid to the surface of the granules in the interior of the body. Further in accordance with the invention such adsorbent body is made by forming a uniform mixture of the granules of adsorbent material and the particles of thermoplastic organic polymer and then heating the mixture to a temperature above the softening temperature but below the melting temperature of the thermoplastic polymer thereby to bond the granules together.
Abstract:
THIS INVENTION PROVIDES A METHOD OF REGENERATING ION EXCHANGE RESINS IN A FLUID BED, WHICH CONSISTS IN LOOSENING, ACTUALLY REGENERATING AND THEREAFTER RINSING THE REGENERATED ION EXCHANGE RESINS AS A CONTINUOUS PROCESS IN A SAME AND SINGLE ENCLOSURE, IN SUPERPOSED SUCCESSIVE ZONES THEREOF, BY POSSIBLY VARYING THE UPWARD SPEED OF THE LIQUIDS CIRCULATING IN EACH ONE OF SAID ZONES IN COUNTER-CURRENT RELATIONSHIP TO THE RESIN FLOW, AS A FUNCTION OF THE SPECIFIC ONE OF THE AFORESAID OPERATIONS WHICH IS BEING PERFORMED IN EACH ONE OF THE AFORESAID ZONES. THE INVENTION ALSO COMPRISES, AN APARATUS FOR CARRYING OUT THIS METHOD, WHICH COMPRISES A COLUMN IN WHICH THE SATURATED RESINS CIRCULATE BY GRAVITY FROM TOP TO BOTTOM WITH THE REGENERATING, WASHING AND RINSING LIQUIDS CIRCULATING IN COUNTER-CURRENT RELATIONSHIP TO THE RESINS.

Abstract:
In an ion exchange apparatus such as for the softening or desalting of water, the active column and the combined regenerating and washing columns are interconnected by pipe systems including counterpressure chambers so that spent ion exchange material is recycled from the active column through the regenerating and washing columns and back to the active column with a balanced rate of flow.
