Der zur Vormischung verwendete Scheideschlamm (Saturationskalk), welcher gleichfalls wertvolle Düngestoff enthält, ist bekanntlich als Abfallprodukt dur   Zuckcrfabrikation   zu sehr billigem Preis erhältlich und hat den Vorzug, dass durch die   Vermischung   mit Stickstoff keine Veränderung desselben eintritt. 



   Der als Filtermaterial verwendete Torfmull hat nicht nur eine mechanische, sondern auch eine chemische Wirkung und das filtrierte Wasser ist deshalb unbedenklich ablassfähig.

The separating sludge used for premixing (saturation lime), which also contains valuable fertilizer, is known to be available as a waste product from sugar production at a very cheap price and has the advantage that it does not change when it is mixed with nitrogen.



   The peat garbage used as filter material has not only a mechanical but also a chemical effect and the filtered water can therefore be safely drained.
