Description

Verfahren zur Verminderung der Karbonathärte von Wasser und zur Entfernung seiner Magnesiahärte Zusatz zur Patentanmeldung M24754IVc/85b (Auslegeschrift 1 097 377) Die Erfindung betrifft eine weitere Ausbildung des Verfahrens zur Verminderung der Karbonathärte von Wasser und zur Entfernung seiner Magnesiahärte nach Patentanmeldung M 24754 IVc/85b durch Vollentbasung eines Teilstromes des Rohwassers mittels Wasserstoffionenaustausches, Sättigung eines zweiten Teilstromes mit Ätzkalk unter Abtrennung der Feststoffe und anschließende Wiedervereinigung beider Teilströme, wobei das Verhältnis zwischen beiden Teilströmen so gewählt wird, daß die im vollentbasten Wasser enthaltene Mineralsäure ganz gebunden, von der im vollentbasten Wasser enthaltenen ursprünglichen Karbonat-Kohlensäure jedoch nur ein Teil in Karbonathärte zurückverwandelt wird. Process for reducing the carbonate hardness of water and for removal its magnesia hardness addition to patent application M24754IVc / 85b (Auslegeschrift 1 097 377) The invention relates to a further embodiment of the method for reduction the carbonate hardness of water and to remove its magnesia hardness according to patent application M 24754 IVc / 85b through complete debasing of a partial flow of the raw water by means of hydrogen ion exchange, Saturation of a second partial flow with quicklime with separation of the solids and subsequent reunification of both substreams, the ratio between two partial streams is chosen so that the mineral acid contained in the fully degassed water completely bound, from the original carbonate-carbonic acid contained in the fully degassed water however only a part is converted back into carbonate hardness.

Der Erfindung liegt die Aufgabe zugrunde, zusätzlich zur wählbaren Verminderung der Karbonathärte und zur Entfernung der Magnesiahärte gemäß der Hauptpatentanmeldung den Gehalt eines Wassers an mineralsauren Salzen zu vermindern oder sie, falls erforderlich, in ein brauchbares Verhältnis zueinander zu bringen oder beide Ziele gleichzeitig zu erreichen. The invention is based on the object, in addition to the selectable Reduction of the carbonate hardness and for the removal of the magnesia hardness according to the main patent application to reduce the content of mineral acid salts in a water or, if necessary, to bring them into a usable relationship to one another or both goals at the same time to reach.

Der Gehalt an mineralsauren Salzen und das Verhältnis derselben untereinander ist wesentlich bei der Aufbereitung von Brauwasser, weil diese Umstände das Brauverfahren sowie den Geschmack und die Haltbarkeit des Bieres beeinflussen. The content of mineral acid salts and the ratio of these to one another is essential in the treatment of brewing water because these circumstances affect the brewing process as well as affect the taste and shelf life of the beer.

Die der Erfindung zugrunde liegende Aufgabe wird dadurch gelöst, daß ein Zweigstrom des dem Wasserstoffionenaustausch unterworfen gewesenen Teilstromes anschließend einem Hydroxylionenaustausch oder einem neutralen Anionenaustausch unterworfen wird oder beide Austauschverfahren je in einem besonderen Zweigstrom des dem Wasserstoffionenaustausch unterworfen gewesenen Teilstromes durchgeführt werden. The object on which the invention is based is achieved by that a branch stream of the partial stream that has been subjected to the hydrogen ion exchange then a hydroxyl ion exchange or a neutral anion exchange is subjected or both exchange processes each in a separate branch stream of the partial stream subjected to the hydrogen ion exchange carried out will.

Im Falle der Anwendung eines Hydroxylionenaustausches wie auch eines neutralen Anionenaustausches wird ein schwachbasisches Ionenaustausch material verwendet, das nur die Mineralsäureanionen beeinflußt. Durch den Hydroxylionenaustausch wird der Gehalt des Rohwassers an mineralsauren Salzen herabgesetzt. Der neutrale Anionenaustausch dient dazu, die mineralsauren Salze untereinander in ein brauchbares Verhältnis zu bringen, also z. B. den Gehalt an Sulfationen in beliebigem Ausmaß durch Chloridionen zu ersetzen. In the case of using a hydroxyl ion exchange as well as one neutral anion exchange, a weakly basic ion exchange material is used, which only affects the mineral acid anions. Due to the hydroxyl ion exchange, the content of mineral acid salts in the raw water is reduced. The neutral anion exchange serves to bring the mineral acid salts to one another in a usable ratio to bring, so z. B. the content of sulfate ions to any extent by chloride ions to replace.

Zur Entfernung der überschüssigen freien Kohlensäure, die in Brauwasser unerwünscht ist, wird das Mischwasser, wie in der Hauptpatentanmeldung angegeben, in an sich bekannter Weise über eine Rieseleinrichtung geführt. To remove the excess free carbon dioxide in brewing water is undesirable, the mixed water, as stated in the main patent application, out in a manner known per se over a trickle device.

Die den Gegenstand des vorliegenden Zusatzpatentes bildenden, das Verfahren gemäß Hautpatentanmeldung ausgestaltenden Maßnahmen sind an sich be- kannt. Ein Patentschutz wird daher für sie allein nicht, sondern nur für das Gesamtverfahren begehrt. The subject of the present additional patent, the Procedures in accordance with the main patent application designing measures are per se knows. A patent protection is therefore not for them alone, but only for the entire process desired.

PATENTANSPRtSCHE: 1. Weitere Ausbildung des Verfahrens zur Verminderung der Karbonathärte von Wasser und zur Entfernung seiner Magnesiahärte nach Patentanmeldung M 24754 IVc/85 b durch Vollentbasung eines Teilstromes des Rohwassers mittels Wasserstoffionenaustausches, Sättigung eines zweiten Teilstromes mit Ätzkalk unter Abtrennung der Feststoffe und anschließende Wiedervereinigung beider Teilströme, wobei das Verhältnis zwischen beiden Teilströmen so gewählt wird, daß die im vollentbasten Wasser enthaltene Mineralsäure ganz gebunden, von der im vollentbasten Wasser enthaltenen ursprünglichen Karbonat-Kohlensäure jedoch nur ein Teil in Karbonathärte zurückverwandelt wird, dadurch gekennzeicfxnet, daß ein Zweigstrom des dem Wasserstoffionenaustausch unterworfen gewesenen Teilstromes anschließend einem Hydoxylionenaustausch oder einem neutralen Anionenaustausch unterworfen wird oder beide Austauschverfahren je in einem besonderen Zweigstrom des dem Wasserstoffionenaustauscli unterworfen gewesenen Teilstromes durchgeführt werden. PATENT CLAIMS: 1. Further development of the process for reduction the carbonate hardness of water and to remove its magnesia hardness according to patent application M 24754 IVc / 85 b by completely debasing a partial flow of the raw water by means of hydrogen ion exchange, Saturation of a second partial flow with quicklime with separation of the solids and subsequent reunification of both substreams, the ratio between two partial streams is chosen so that the mineral acid contained in the fully degassed water completely bound, from the original carbonate-carbonic acid contained in the fully degassed water however, only a part is converted back into carbonate hardness, thereby marked, that a branch stream of the partial stream that has been subjected to the hydrogen ion exchange then subjected to a hydroxyl ion exchange or a neutral anion exchange or both exchange processes each in a special branch stream of the hydrogen ion exchange be carried out subjected to partial flow.
