  Verfahren zur Erhöhung der Basenaustauschfähigkeit des Xiederschlages aus Wasserglas und gelösten Eisensalzen.

   manganung hervor,   denn es gibt kein Produkt, mit welchem neben den vorgenannten Wirkungen auch noch eine rationelle Enthärtung    durchführbar wäre.   



   Selbst wenn man aber davon   absieht, dass   bei diesem vorbekannten Verfahren ein anderer

 so ist die Weiterbehandlung des Körpers jedenfalls anders als bei dem vorliegenden Verfahren. Bei diesem handelt es sich darum, den aus Wasserglas und in Lösung befindlichem Eisenchlorid entstandenen Niederschlag mit der austauschfähigen Base anzureichern. Diese kann im gegenwärtigen Falle nur Kali-oder Natron sein und¯demgemäss muss auch die Behandlung mit entsprechenden Chemikalien, also Natriumkarbonat oder Ätznatron oder Kaliumkarbonat oder Ätzkali, erfolgen. Am zweckmässigsten haben sich die ersteren erwiesen, und zwar, bei möglichst   heisser) am   besten aber kochender Anwendung.

   Ammoniak ist keine für die praktische Wasserreinigung in Betracht kommende Base, und ob es überhaupt in vorliegende Kieselsäureverbindung als praktisch austauschfähige Base aufgenommen wird, ist unwahrscheinlich. Die Behandlung mit Ammoniak könnte also keine Verbesserung der Basenaustauschfähigkeit im Gefolge haben. 



   PATENT-ANSPRÜCHE : i. Verfahren zur Erhöhung der   Basenaustauschfähigkeit   des Niederschlages aus Wasserglas und gelösten Eisensalzen,   dadurch gekennzeichnet,'dass   der angeführte Niederschlag mit Alkalilauge in der Wärme behandelt wird.

   Manganung, because there is no product with which, in addition to the aforementioned effects, an efficient softening could be carried out.



   Even if one disregards the fact that with this previously known method another
 EMI2.1
 in any case, the further treatment of the body is different from the present procedure. This is about enriching the precipitate formed from water glass and ferric chloride in solution with the exchangeable base. In the present case, this can only be potash or soda and accordingly the treatment with corresponding chemicals, that is to say sodium carbonate or caustic soda or potassium carbonate or caustic potash, must also take place. The former have proven to be the most appropriate, namely when used as hot as possible, but preferably at boiling.

   Ammonia is not a suitable base for practical water purification, and it is unlikely that it will be included in the present silicic acid compound as a practically exchangeable base. Treatment with ammonia could therefore not result in any improvement in the base exchange capacity.



   PATENT CLAIMS: i. Process for increasing the base exchange capacity of the precipitate made from water glass and dissolved iron salts, characterized in that the precipitate mentioned is treated with hot alkali.
