   Bei pulverigen Materialien oder solchen, welche vor dem Formen gemahlen werden, kann man die zur Trockne eingedampfte Ablauge dem Material zusetzen und damit vermahlen oder anderweitig damit mischen. Zu diesem Gemisch braucht man nur Wasser zuzusetzen, um die gewünschte Formbarkeit zu erzielen.

   In the case of powdery materials or those which are ground before molding, the waste liquor that has been evaporated to dryness can be added to the material and ground with it or otherwise mixed with it. You only need to add water to this mixture in order to achieve the desired formability.

PATENT-ANSPRUCH : Verfahren zur Behandlung von Sulfitablaugen unter Neutralisation und nachfolgendem Eindampfen unter Luftabschluss, dadurch gekennzeichnet, dass die Ablaugen unmittelbar nachdem sie eben neutralisiert, aber nicht alkalisch gemacht worden sind (d. i. ohne Zusatz von über- EMI2.1 neutralisierten Laugen eine verhältnismässig klare, haltbare und viskose Masse von hoher Klebund Bindekraft zu erzielen. PATENT CLAIM: Process for the treatment of sulphite waste liquors with neutralization and subsequent evaporation in the absence of air, characterized in that the waste liquors have just been neutralized but not made alkaline (i.e. without the addition of excess EMI2.1 neutralized alkalis to achieve a relatively clear, durable and viscous mass with high adhesive and binding power.
