  Reinigung von   Salzlösungen   mittels Trass. 



   Es ist bekannt, dass Zeolithe die Eigenschaft haben, aus wässerigen Lösungen die Basen von Kalksalzen und Magnesiumsalzen sowie auch andere Basen, wie Eisen und Mangan, auf dem Wege des Austausches aufzunehmen und dass nach Erschöpfung der Austauschfähigkeit der erschöpfte Zeolith durch Behandlung mit der Lösung eines Salzes der von ihm ausgetauschten Basis, z. B. Chloriden, wieder zu dem ursprünglichen Zeolith regeneriert werden kann. Hat man z. B. Zeolith benutzt, um Wasser zu entkalken (enthärten), so kann man durch Behandlung mit einer Chlornatriumlösung regenerieren, die dabei in eine   Chlorcalciumlösung   umgewandelt wird. 



   Nun haben Versuche ergeben,   dar.   Trass und sonstige trachytische Tuffe dieselbe Eigenschaft, und zwar in hohem Grade zeigen. Beispielsweise wird eine Chlornatriumlösung durch Überleiten in eine   Chlorcalciumlösung     übergeführt,   und umgekehrt, eine   Chlorcakium-   lösung in eine Chlornatriumlösung, und in derselben Weise werden die Bikarbonate   dob   Kalkes und der Magnesia und ebenfalls die Sulfate und Chloride dieser Erdalkalien in die entsprechenden Natriumsalze umgewandelt. 



   Die Ausscheidungen aus konzentrierten und verdünnten Lösungen erfolgen gleich gut. Man kann auf diese Art in schnellster Weise   kesselstoinbildende   Kalk-und Magnesiasalze des Wassers ohne Schwierigkeiten quantitativ aus dem Wasser entfernen und auch andere Basen, welche   schädlich sein können, wie Eisenoxydul   und   Manganoxydul   aus dem Wasser abscheiden. Dabei   macht   es keinen Unterschied, ob das Wasser weniger oder mehr Härtegrade aufweist ; es wird durch Überleiten über Trass oder sonstige trachytiseho Tuffe unter Beobachtung bestimmter Geschwindigkeiten des Wassers auf   0"enthärtet.   



   Beispielsweise kann Wasser von 12 bis 15 deutschen   Härtegraden über   eine Filterschicht von 500 mm   aus Trass odür andoren trachytischen Tuffen bei   einer Geschwindigkeit von   1#5 bis 2 m enthärtet werdne.   



   Der Trass oder die anderen trachytischen Tuffe werden den   Umständen   entsprechend in mehr oder minder feinen Korn- oder Stückgrössen in Anwendung gebracht,   und IWl1r   einmal in Form eines Filters, wobei die Filtration sowohl achsial (von oben nach unten oder umgekehrt) oder auch radial stattfinden kann, ferner in Form eines Bades, durch das die zu behandelnde   Flüssigkeit   geleitet wird, und   schliesslich   dadurch, dass   der Trass oder   die anderen   trachytischen Tuffe   in dosierten Mengen den Salzlösungen zugegeben werden.

  Purification of salt solutions using trass.



   It is known that zeolites have the property of the bases of calcium salts and magnesium salts as well as other bases, such as iron and manganese, from aqueous solutions to take up on the way of the exchange and that after exhaustion of the exchangeability of the exhausted zeolite by treatment with the solution Salt of the base he has exchanged, e.g. B. chlorides, can be regenerated back to the original zeolite. Has one z. B. zeolite is used to decalcify (soften) water, it can be regenerated by treatment with a sodium chloride solution, which is converted into a calcium chloride solution.



   Experiments have now shown that trass and other trachytic tuffs show the same property, and indeed to a high degree. For example, a sodium chloride solution is converted into a calcium chloride solution by passing it over, and vice versa, a calcium chloride solution is converted into a sodium chloride solution, and in the same way the bicarbonates of lime and magnesia and also the sulphates and chlorides of these alkaline earths are converted into the corresponding sodium salts.



   The excretions from concentrated and dilute solutions are equally good. In this way, kettle-stoin-forming lime and magnesia salts of the water can be removed quantitatively from the water without difficulty, and other bases which can be harmful, such as iron oxide and manganese oxide, can also be separated from the water. It makes no difference whether the water has less or more degrees of hardness; it is softened to 0 "by passing over trass or other trachytic tuffs while observing certain speeds of the water.



   For example, water with a hardness of 12 to 15 German degrees of hardness can be softened through a filter layer of 500 mm made of trass or andore trachytic tuffs at a speed of 1 5 to 2 m.



   The trass or the other trachytic tuffs are used in more or less fine grain or piece sizes depending on the circumstances, and once in the form of a filter, with the filtration taking place axially (from top to bottom or vice versa) or also radially , also in the form of a bath through which the liquid to be treated is passed, and finally in that the trass or the other trachytic tuffs are added to the salt solutions in dosed quantities.
