Use of ash as an alternative alkalising agent

The industrial/incinerator ash or chemically/physically modified ash for alkalization of solid, liquid or gaseous systems. The systems have a pH value greater than 7. The ash is used for adjusting the water hardness. The solid, liquid, or gaseous systems are water, waste water, process water, closed...

Beschreibung
Zusammenfassung:	The industrial/incinerator ash or chemically/physically modified ash for alkalization of solid, liquid or gaseous systems. The systems have a pH value greater than 7. The ash is used for adjusting the water hardness. The solid, liquid, or gaseous systems are water, waste water, process water, closed loop water, waste paper, wood fibers, textiles, exhaust gases, sludges, biosludges, clarifying sludges and residues. The amount of ash is 0.001-100 wt%. Die vorliegende Erfindung beschreibt den Einsatz von Asche oder Aschederivaten zur Alkalisierung und Pufferung kommunaler, industrieller und häuslicher Systeme. Durch den Einsatz von Asche, insbesondere in der Papierindustrie, können bei gleicher oder besserer Qualität kostengünstige Alternativen zu den herkömmlich verwendeten Alkalisierungsmitteln angeboten werden.
