Description

Verfahren zur Entfernung von Kolloiden aus Lösungen Gelöste Kolloide lassen sich nicht durch gewöhnliche Filter, ja oftmals sogar nicht durch Kolloidfilter, aus Lösungen entfernen. Zur Entfernung von Kolloiden aus Lösungen muß man vielmehr die Kolloide ausflocken oder an unlösliche Adsorptionsmittel binden. Process for removing colloids from solutions. Dissolved colloids cannot be passed through ordinary filters, and often not even through colloid filters, remove from solutions. Rather, it is necessary to remove colloids from solutions the colloids flocculate or bind to insoluble adsorbents.

Hierzu sind bestimmte Tone, die ein Tonmineral der Montmorillonitgruppe oder des Attapulgits oder des Halloysits enthalten, wie Bentonite, Bleicherden, Walkerden, Fullererden oder spanische Erde, oder ähnliche synthetische Produkte geeignet. Ihre Anwendung hat sich z. B. sehr gut bewährt zur Entfernung von Eiweiß aus Wein, Bier, Molke, Zuckersäften u. dgl., zur Entfernung organischer Kolloide und kolloider Schmutzstoffe aus Abwässern, zur Entfernung von Fäulnisprodukten des Eiweißes, zur Entfernung jeder Art organischen Aminen u. a. m. Dabei kann z. B. ein guter Bentonit mehr als sein eigenes Gewicht an kolloidgelöstem Eiweiß aus der Lösung entfernen.For this purpose, certain clays, which are a clay mineral of the montmorillonite group or of attapulgite or halloysite, such as bentonite, bleaching earth, Fuller's earth, full earth or Spanish earth, or similar synthetic products suitable. Your application has z. B. has proven its worth for removing protein from wine, beer, whey, sugar juices and the like to remove organic colloids and colloidal contaminants from sewage, for the removal of putrefaction products of the Egg white, for the removal of all kinds of organic amines, among others. m. B. a good bentonite more than its own weight in colloid-dissolved protein from the Remove solution.

Die Anwendung dieser Tone bringt aber andererseits auch Nachteile mit sich, weil sie, insbesondere wenn das PH der Lösung nicht stark sauer ist, zu starker Quellung neigen und darum der durchfließendenLösung sehr hohen Widerstand entgegensetzen, sich schlecht absetzen und sich sehr schlecht filtrieren lassen. On the other hand, however, the use of these clays also has disadvantages with itself because it, especially if the pH of the solution is not strongly acidic, too tend to swell and therefore the solution flowing through has very high resistance oppose, settle poorly and filter very poorly.

Diese Nachteile können erfindungsgemäß vermieden werden, wenn man Tone, deren Tonmineral der Montmorillonitgruppe oder dem Attapulgit oder Halloysit angehört, oder ein diesen Mineralien gleichwertiges synthetisches Produkt in an sich bekannter Weise in geeignete Fasergeflechte einbettet, beispielsweise sie an Stelle anderer Füllstoffe z. B. in Papier (Zellstoffvliese) od. dgl. füllt und die so beladenen Fasergeflechte zum Entfernen von Kolloiden aus Lösungen verwendet. These disadvantages can be avoided according to the invention if one Clays, their clay mineral of the montmorillonite group or the attapulgite or halloysite or a synthetic product equivalent to these minerals embeds itself in a known manner in suitable fiber braids, for example on them Instead of other fillers e.g. B. in paper (cellulose fleece) od. Like. Fills and the so loaded fiber braids are used for removing colloids from solutions.

Entgegen der an sich zu befürchtenden Erwartung, daß durch eine solche Einbettung derartiger Tone in Fasergeflechte die wirksame Oberfläche der Tonteilchen vermindert und auch sonst durch eine Wechselwirkung zwischen Tonteilchen und Fasergeflecht die Aktivität der Tonteilchen noch weiter beeinträchtigt würde, hat sich überraschenderweise herausgestellt, daß in derartigen Spezialfiltermassen alle wertvollen Eigenschaften der genannten Tone, d. h. ihre Fähigkeit zur Adsorption koiloidgelöster Stoffe, ungemindert erhalten bleiben, während ihre nachteiligen Eigenschaften, d. h. ihre Neigung zu einer starken Quellung, ihre schlechte Absetzbarkeit und ihre schlechte Filtrierbarkeit, die bisher in Kauf genommen werden mußten, völlig ausgeschaltet werden, indem das Fasergeflecht die Bildung eines undurchlässigen Materials verhindert. Contrary to the feared expectation that such a Embedding such clays in fiber braids is the effective surface of the clay particles reduced and otherwise due to an interaction between clay particles and fiber mesh The activity of the clay particles would be further impaired, surprisingly found that in such special filter media all valuable properties of said clays, d. H. their ability to adsorb coiloid solutes, are maintained undiminished while their disadvantageous properties, i. H. their Tendency towards severe swelling, their poor settling ability and their bad Filterability, which previously had to be accepted, is completely eliminated The fiber braid prevents the formation of an impermeable material.

Diese Effekte sind dabei als um so überraschender zu bezeichnen, als an sich nicht nur, wie oben bereits angedeutet, anzunehmen war, daß durch die Kombination mit Fasergeflecht das Adsorptionsvermögen der genannten Tone, z.B. gegenüber Eiweißstoffen, wesentlich gemindert würde, sondern auch an sich durchaus zu erwarten war, daß die Beladung bzw. These effects are to be described as all the more surprising, than in itself not only, as already indicated above, could be assumed that through the Combination with fiber braid the adsorption capacity of the clays mentioned, e.g. against Protein substances, would be significantly reduced, but also to be expected in itself was that the load or

Füllung von Fasergeflechten mit gleichen oder gar noch größeren Gewichtsmengen derartiger Tone nicht etwa zu Produkten führen würde, welche bei der Benutzung als Filter nicht auseinanderfallen, sondern durchaus stabil bleiben und so einen ausgezeichneten wirtschaftlichen Einsatz ermöglichen.Filling of fiber braids with the same or even larger amounts of weight such clays would not lead to products which, when used as a Filters do not fall apart, but remain quite stable and such an excellent one enable economical use.

Derartige Fasergeflechte können in der Tat ohne irgendwelche Beeinträchtigung so viel von dem Ton aufnehmen, daß die Hälfte ihres Gewichtes oder mehr aus dem Ton besteht. Der Ton wird in dem Fasergeflecht dabei so fest gehalten, daß er beim Filtrieren durch dasselbe ebenso wie beim Vorbeilaufen der Lösung an Streifen eines derart gefüllten Fasergeflechtes in einer Austauschersäule, ja sogar beim intensiven Schütteln -der Lösung mit Schnitzeln eines derart gefüllten Fasergeflechtes nicht oder nur in ganz ge ringfügigen Mengen ausgewaschen wird. Such fiber braids can in fact without any impairment take up so much of the sound that half its weight or more is off the There is sound. The clay is held so firmly in the fiber network that it is at Filter through the same as when passing the solution on strips of one fiber braid filled in this way in an exchange column, even in the intensive one Do not shake the solution with chips of a fiber mesh filled in this way or is only washed out in very small amounts.
