摘要:
An ion exchanger includes a sheet-shaped positive ion exchanger 2 in which binder particles 5 and positive ionic exchange resin particles 4 are mixed with each other, and a sheet-shaped porous negative ion exchanger 3 in which binder particles 7 and negative ionic exchange resin particles 6 are mixed with each other, the positive ion exchanger 2 and the negative ion exchanger 3 are bonded to each other to form an interface, and capacity of the negative ion exchanger 3 is greater than that of the positive ion exchanger 2. Therefore, the porous ion exchanger 1 is formed and absorbing ability of ion is increased, capacity of the negative ion exchanger 3 is made greater than that of the positive ion exchanger 2, regenerating ability of the ion exchanger with respect to absorbing ability of ion can be secured, and ion absorption and regeneration processing is carried out efficiently.

A system and method for providing mobile or temporary water treatment involving ion exchange resins includes a service center, one or more treatment vehicles, a resin transfer hub and one or more resin transport vehicles. The service center can be used to regenerate one or more types of ion exchange resins. The treatment vehicle carries water treatment equipment including a tank holding ion exchange resin. The resin transfer hub facilitates moving resin between a treatment vehicle and a resin transport vehicle. The resin transport vehicle is adapted for carrying resin by one or more of land, sea and air between the resin forwarding center and the service center. In operation, a treatment vehicle brings resin requiring regeneration to the resin transfer hub, where it is emptied and then re-filled with regenerated resin. Resin requiring regeneration is transferred to a resin transport vehicle for transport to the service center. The resin transport vehicle is re-filled there with regenerated resin, which is taken back to the resin transfer hub for transferred to a treatment vehicle.

The method for separating and transferring an ion-exchange resin contains the following essential steps: (1) a first step in which the mixed resin bed is separated into two layers by backwashing and the greater part of the ion-exchange resin (SBR) having the lower specific gravity is transferred by means of a perforated sluicing pipe that is disposed below the interface between the separated resin layers and a resin transfer pipe that is disposed above said sluicing pipe; (2) a second step in which SBR that is left untransferred in the first step is separated to be situated above the layer of the ion-exchange resin (SAR) having the higher specific gravity; and (3) a third step in which sluicing water is introduced into the tank at high flow rate through the sluicing pipe so that the particles of SBR are lifted in the water in the freeboard above the resin layer, while pressurized water is introduced from the top of the tank so as to transfer the residual SBR through the resin transfer pipe.

摘要:
A device and a method for the regeneration of ion exchange resin mixed beds, used for the desalination of water or of aqueous solutions deriving from industrial processes (process solutions), that use two columns: the first treatment column (C1), containing a mixed bed of ion exchange resins, in which the cation exchange resins are regenerated, and a second column (C2) into which the anion exchange resins are transferred and regenerated, to be then reintroduced from the bottom into the above mentioned first column (C1), where they rise through the cation exchange resins intimately mixing themselves with them.
摘要:
Bei dem Verfahren zur Entsalzung von salzhaltigen, wässrigen Lösungen benützt man ein Mischbettfilter, dem mindestens ein Kationenaustauscherharzfilter und mindestens ein Anionenaustauscherharzfilter vorgeschaltet sind. Das Mischbettfilter wird ebenso wie die Kationen- und Anionenaustauscherharzfilter als Arbeitsfilter betrieben. Die zur Regeneration der Ionenaustauscherharze des Mischbettfilters verwendeten Regeneriermittellösungen werden danach zur Regeneration der Ionenaustauscherharze der vorgeschalteten Kationen- und Anionenaustauscherharzfilter verwendet. Zur Durchführung dieses Verfahrens eignet sich eine Einrichtung mit einer Vorrichtung zur gleichzeitigen Abnahme der zur Regeneration der Ionenaustauscherharze des Mischbettfilters verwendeten Regeneriermittellösungen. Bei dieser Vorrichtung sind oberhalb bzw. unterhalb der Trennfläche (4) zwischen den auf hydraulischem Wege getrennten Ionenaustauscherharze (5, 6) zwei horizontal verlaufende Flüssigkeitsableitsysteme (1, 2) angeordnet. Somit können die Regeneriermittellösung für die obere Ionenaustauscherharzschicht (5) durch das obere Flüssigkeitsableitsystem (1) und die Regeneriermittellösung für die untere Ionenaustauscherharzschicht (6) durch das untere Flüssigkeitsableitsystem (2) getrennt abgezogen werden. Zwischen den beiden Flüssigkeitsableitsystemen (1, 2) ist vorzugsweise ein horizontal verlaufendes Flüssigkeitseinleitsystem (3) angeordnet.
