  Verfahren zum Enthärten von Wasser. 



   Den Gegenstand des vorliegenden Patentes bildet ein Verfahren zum Enthärten von Wasser, und zwar mittels des für diese Zwecke bekannten Natriumphosphates. Der Erfinder hat festgestellt, dass die Enthärtung mit diesem Mittel ganz besonders schnell und gründlich stattfindet, wenn das Wasser, nachdem das Natriumphosphat (Na2HPO4) in ihm aufgelöst ist, auf höhere Temperatur, am besten auf Kochtemperatur gebracht wird. Durch diese Art der Verwendung wird sowohl die Zeit der   Enthärtung   abgekürzt, wie auch die Enthärtung zu einem solchen Grade durchgeführt, wie es bisher nicht möglich war. 



   In folgendem wird ein Beispiel für das Verfahren gegeben : 
 EMI1.1 
 langem Kochen auf 1  herabgegangen.

  Process for softening water.



   The subject of the present patent is a method for softening water, specifically by means of sodium phosphate, which is known for this purpose. The inventor has found that softening with this agent takes place particularly quickly and thoroughly if the water, after the sodium phosphate (Na2HPO4) has dissolved in it, is brought to a higher temperature, preferably to boiling temperature. This type of use both shortens the softening time and makes softening to a degree that was previously not possible.



   The following is an example of the procedure:
 EMI1.1
 decreased to 1 for a long time.
