K. und TH. MÖLLER in KUPFERHAMMER bei BRACKWEDE. Verfahren der Reinigung von Fabrikwässern, welche suspendirte Stoffe enthalten.K. and TH. MÖLLER in KUPFERHAMMER at BRACKWEDE. Process for the purification of factory water which contains suspended matter.

Zusatz-Patent zu No. 7014 vom 20. August 1878.Patent addition to No. 7014 of August 20, 1878.

Patentirt im Deutschen Reiche vom II. October 1879 ab. Längste Dauer: 19. August 1893.Patented in the German Empire on October 2nd, 1879. Longest duration: August 19, 1893.

In der Beschreibung des Haupt-Patents war nur .die Einleitung der Kohlensäure durch ein auf dem Boden des Absetzgefäfses liegendes Rohr vorgesehen. In vielen Fällen,' namentlich da, wo die Absetzbassins weit von den Fabriken und Dampfkesseln entfernt sind, ist es schwierig, die Kohlensäure auf diese Weise einzuleiten. Alsdann soll das mit Aetzkalk behandelte Abgangswasser auf ein Gradirwerk, wie es bei Salinen üblich ist, oder über ein Haufwerk von Coks oder anderen porösen Körpern, durch welche die atmosphärische Luft streicht, gepumpt werden; ebenso kann man die Flüssigkeit auch über eine schwach geneigte Fläche rieseln lassen, auf die eventuell poröse organische oder anorganische Stoffe geworfen werden. Auf diese Weise findet der im ersten Theil des Processes gelöste Aetzkalk Gelegenheit, sich mit der Kohlensäure der Luft zu verbinden. Die Flüssigkeit fliefst, nachdem sie genügend Kohlensäure aufgenommen hat, in Absetzbassins bezw. Teiche, wo sich die Niederschläge absetzen.In the description of the main patent there was only the introduction of the carbonic acid by a provided pipe lying on the bottom of the sedimentation vessel. In many cases, 'by name where the sedimentation basins are far from the factories and boilers, it is difficult to initiate the carbonic acid in this way. Then the waste water treated with caustic lime should be used on a graduation, as is usual with salt pans, or over a pile of coke or other porous bodies which sweep the atmospheric air are pumped; likewise one can use the liquid also let trickle over a slightly inclined surface onto the possibly porous organic or inorganic substances are thrown. In this way, in the first part of the Processes dissolved caustic lime opportunity to combine with the carbonic acid of the air. the After it has absorbed enough carbonic acid, liquid flows into settling basins or. Ponds where the precipitation settles.

In manchen Fällen genügt der Kalkzusatz nicht, um eine schnelle Reinigung zu bewirken. Dieselbe wird besser erreicht, wenn nach der Reinigung mit Aetzkalk noch Aetzbaryt zugesetzt wird; das Verfahren ist im übrigen genau wie das beim Kalk beschriebene. Der Aetzbaryt wird aus dem niederfallenden Baryumcarbonat durch Glühen des Niederschlages wieder gewonnen, indem die beigemengten organischen Substanzen verbrennen. Eventuell kann man auch mit Aetzbaryt allein reinigen.In some cases, the addition of lime is not enough to cause quick cleaning. Same is better achieved if abrasive barite is added after cleaning with quicklime will; the procedure is otherwise exactly the same as that described for lime. The Aetzbaryt is recovered from the falling barium carbonate by glowing the precipitate, by burning the added organic substances. It may also be possible to clean with carbon dioxide alone.
