  Verfahren zur Herstellung eines Filtermaterials von hoher Oberflächenwirkung.

 <Desc/Clms Page number 2> 

 ganz ausserordentlich das Wachstum von Spaltpilzen. So wertvoll aber ein guter Anteisenungseffekt ist, so sehr fällt der hygienische Nachteil ins Gewicht. 



   Gemäss der Erfindung wird ein erheblicher gewerblicher Fortschritt dadurch erzielt, dass die Möglichkeit geschaffen wird, ein Material anorganischer Herkunft in der Art zu behandeln, dass nun auch an und in ihm der feinste Niederschlag so fest haftet, dass er sich durch Auswaschen selbst unter Zuhilfenahme von   Rührvorr :

   chtungen   nicht wieder ganz entfernen lässt, so dass der mit im qualitativ erzielte Effekt den mit Holzwolle erzielten 
 EMI2.1 
 sehr vorteilhaften   Ausführungsbeispiel   Eiweisskörper in Form von Schlachtblut mit Alkali in   in% niger   Lösung abgebaut, die Steine mit dieser Lösung getränkt, getrocknet, alsdann 
 EMI2.2 
 vorbereiteten porösen Steine wirken in vorliegender Hinsicht wie organische Substanz, d. h. sie halten vermittelst der Kohle soviel katalytisch wirksamen Niederschlag trotz sorgsamen Auswaschens in sich fest, dass das aus ihnen hergestellte Filter gleichmässig und qualitativ günstig arbeitet.

   Um nun aber die beabsichtigte Wirkung gleich von vornherein zu erzielen, werden nach der Erfindung in bekannter Weise durch Tränkung mit mehreren Reagenzien, die fällende Wirkung aufeinander   ausüben, Metallhydroxyde   und Calciumcarbonat in den Steinen niedergeschlagen. 



     Beispiel : Gekörnter poröser   Ziegelstein wird mit   i seiger,   alkalisch erzeugter, 
 EMI2.3 
 geeigneten Gefäss ausgewaschen und dann zuerst mit Lösungen von Eisen-AluminiumMangan-Nickel-Kobaltsalzen   getränkt. Nun fällt   man mit Kalkwasser, dem man Gips zugefügt hat, die Hydroxyde und nachher durch ein lösliches Carbonat aus dem Gips Calciumcarbonat.

 EMI1.1
 

 <Desc / Clms Page number 2>

 the growth of fissure fungi is extraordinary. As valuable as a good iron removal effect is, the hygienic disadvantage is just as important.



   According to the invention, a considerable commercial advance is achieved by creating the possibility of treating a material of inorganic origin in such a way that the finest precipitate adheres so firmly to and in it that it can be washed out with the aid of Agitator:

   can not be completely removed again, so that the qualitative effect achieved with wood wool
 EMI2.1
 Very advantageous embodiment, protein bodies in the form of slaughter blood are broken down with alkali in a% solution, the stones are soaked in this solution, then dried
 EMI2.2
 Prepared porous stones act like organic matter in the present case, i. H. By means of the coal, they hold on to so much catalytically effective precipitate in spite of careful washing out that the filter made from them works uniformly and with good quality.

   In order to achieve the intended effect right from the start, metal hydroxides and calcium carbonate are precipitated in the stones according to the invention in a known manner by impregnation with several reagents which exert a precipitating effect on one another.



     Example: Grained porous brick is produced with i seiger, alkaline,
 EMI2.3
 Washed out a suitable vessel and then soaked first with solutions of iron-aluminum-manganese-nickel-cobalt salts. The hydroxides are now dropped with lime water to which gypsum has been added, and then calcium carbonate from the gypsum through a soluble carbonate.
