Description

Verfahren zur Enteisenung eisenhaltiger Wässer. Die Enteisenung von Brunnen- oder Flußwässern wird zumeist so durchgeführt, daß das Wasser z. B. in offenen Rieselapparaten stark belüftet oder in geschlossenen Behältern, die mit porösem Material gefüllt sind, behandelt wird. Die Entfernung des Eisens ist dabei immer eine mehr oder weniger unvollständige. Insbesondere werden huminhaltige Wässer durch einfache Belüftung meist nur ganz ungenügend gereinigt.Process for de-ironing ferrous water. The iron removal of Well or river water is usually carried out so that the water z. Am strongly ventilated open sprinklers or in closed containers that come with porous material are filled, is treated. The removal of the iron is included always a more or less incomplete one. In particular, water containing humine usually only inadequately cleaned by simple ventilation.

Es wurde nun gefunden, daß der Eisengehalt des Wassers leicht und vollkommen beseitigt werden kann durch Behandlung mit aktiver Kohle.It has now been found that the iron content of the water is slightly and can be completely eliminated by treatment with active charcoal.

Die Anwendung aktiver Kohle zur Wasserreinigung beschränkte sich bisher auf die Trinkwasserreinigung, wo es sich darum handelt, Farbstoffe, Mikroorganismen, Fäulnisprodukte aller Art, giftige und übelriechende Gase usw. zu entfernen. Dagegen kam es hierbei nicht darauf an, auch das Eisen zu entfernen, da Eisen nicht zu den gesundheitsschädlichen Bestandteilen eines Trinkwassers gehört (im Gegenteil werden stark eisenhaltige Wässer als Heilquellen gegen Blutarmut u. dgl. empfohlen). Auch Abwässer mittels aktiver Kohle zu entfärben, zu entgiften und zu desodorieren wurde bereis vorgeschlagen.The use of active charcoal for water purification has so far been limited on drinking water purification, where it is a question of dyes, microorganisms, To remove all kinds of putrefaction products, toxic and foul-smelling gases, etc. Against it It did not matter here to remove the iron as well, since iron does not belong to the harmful components of drinking water are heard (on the contrary strongly iron-containing waters as medicinal springs against anemia and the like recommended). Even To decolorize, detoxify and deodorize wastewater using active charcoal already suggested.

Demgegenüber beruht die Erfindung auf der neuen Erkenntnis, daß aktive Kohle gelöste Eisensalze aus dem Wasser vollkommen quantitativ zu entfernen vermag. Dieses spezifische Verhalten dieser Kohle gegenüber Eisensalzen war bisher unbekannt und auch in keiner Weise vorauszusehen, zumal andere Salze, wie z. B. Kochsalz oder Kalksalze, nicht adsorbiert werden. Auf diese Erkenntnis gründet sich das neue Verfahren, welches die aktive Kohle einem ganz neuen Zwecke, nämlich der völligen Enteisenung von Wasser, insbesondere von technischem Gebrauchswasser, dienstbar macht.In contrast, the invention is based on the new knowledge that active Coal is able to completely and quantitatively remove dissolved iron salts from the water. This specific behavior of this coal towards iron salts was previously unknown and in no way to be foreseen, especially since other salts, such as. B. table salt or Calcium salts, not to be adsorbed. The new procedure is based on this knowledge, which the active coal has a completely new purpose, namely, complete iron removal of water, in particular of technical service water, makes serviceable.

Eine Belüftung ist in der Regel nicht erforderlich. Nötigenfalls kann sie in bekannter Weise angewendet werden. Das Verfahren hat außerdem noch den großen Vorteil, daß nebenher auch andere gelöste oder fein suspendierte Verunreinigungen von der Kohle absorbiert und somit aus dem Wasser entfernt werden. Man erhält infolgedessen schon durch einfaches inniges Mischen des eisenhaltigen Rohwassers mit der aktiven Kohle und darauffolgendes Filtrieren ein praktisch vollkommen eisenfreies, klares und helles Wasser.Ventilation is usually not required. If necessary, can they are used in a known manner. The procedure also has the big one Advantage that also other dissolved or finely suspended impurities absorbed by the coal and thus removed from the water. As a result, one obtains simply by intimately mixing the ferrous raw water with the active one Charcoal and subsequent filtration a practically completely iron-free, clear and white water.

Das Verfahren kann beispielsweise folgendermaßen ausgeführt werden: Dem Rohwasser wird durch eine Zweigleitung die angeschlämmte aktive Kohle zugeführt. Rohwasser und Kohleschlamm gelangen dann in einen Mischkessel, worin sie durch ein Rührwerk gehörig durchgemischt werden. Darauf gelangt das Wasser samt der Kohle in einen geschlossenen größeren Kessel mit geeigneten Filtern, z. B. Sandfiltern, wo das Wasser durch Filtration unter Druck von der Kohle und allen ausgeschiedenen Verunreinigungen getrennt wird. Die Mischung von Kohle und Wasser kann natürlich auch auf beliebige andere Weise, z. B. durch Preßluft u. dgl., bewerkstelligt werden.The method can be carried out, for example, as follows: The suspended active coal is fed to the raw water through a branch line. Raw water and coal sludge then pass into a mixing tank, in which they pass through a The agitator must be thoroughly mixed. This is where the water and the coal get on in a closed larger boiler with suitable filters, e.g. B. sand filters, where the water is excreted by filtration under pressure from the coal and all Impurities is separated. The mixture of coal and water can of course also to any other way, e.g. B. by compressed air and the like will.
