Die bei dem vorliegenden Verfahren der Enteisenung von Wasser gelösten EisenVerbindungen entstandenen niederen Oxydationsstufen des Mangans lassen sich durch   Behandeln   der Zeolithmasse mit leicht Sauerstoff abgebenden Substanzen, wie Permanganate, Manganate, Persulfate, Ozon etc., leicht wieder in die höheren   Manganoxyde zurück ver-   wandeln,

   worauf die mit letzterem   durchsetzte Zeo1ithmHsse   von neuem zur Enteisenung des Wasser verwendet werden kann. 



   Zugleich mit dem Eisen wird durch   vorliegendes Verfahren auch etwa im Wasser   gelöst vorhandenes Mangan aus dem Wasser entfernt.

  Process for removing iron from water.
 EMI1.1
 the water to be freed from iron is treated with insoluble higher oxides of manganese with the help of natural or artificial zeolites. If, for example, calcium zeolites are first treated with manganese oxide solutions, then there is
 EMI1.2
 treatment with permanganates with deposition of higher manganese oxides react according to the following equation:
 EMI1.3
 
In this way, the manganese is oxidized to a higher degree than is brownstone.

   This higher manganese oxide permeates the zeolite, which is easily permeable to water, in fine distribution, to which it adheres firmly and gives its oxygen substantially
 EMI1.4
 Water by oxidation of the same by the higher manganese oxides finely distributed in the zeolite even when the water is filtered through the zeolite mass with a filtration
 EMI1.5
 
The low levels of manganese oxidation resulting from the present process of de-iron removal from water can easily be converted back into the higher manganese oxides by treating the zeolite mass with easily oxygen-releasing substances such as permanganates, manganates, persulfates, ozone, etc.

   whereupon the zeolite, interspersed with the latter, can be used again to remove iron from the water.



   At the same time as the iron, the present process also removes any manganese present dissolved in the water from the water.



     PATENT APPLICATIONS:
1. A method for removing iron from water, characterized in that the water is treated with insoluble higher oxides of manganese with the help of natural and artificial zeolites.
