  Verfahren zur Klärung von Wasser. 



   Bei der bekannten Klärung des Wassers mit schwefelsaurer Tonerde, wie solche sowohl für Trinkwasser als auch für industrielle Zwecke bei Schnellfilteranlagen in Anwendung kommt, besteht der   Übelstand,   dass bei Wässern, welche nur eine geringe temporäre Härte habenund dies ist bei den in Frage kommenden Oberflächenwässern sehr häufig der Fall - keine genügende Flockenbildung eintritt, um besonders bei grösserem Schlammgehalt des Wassers diese in solcher Menge zu erzeugen, dass sie den Schlamm zu Boden zu reissen vermögen. Ausserdem tritt die Reaktion bei geringer temporärer Härte des Wassers nur langsam ein und waren daher bisher grosse und teure   Vorkläranlagen   erforderlich.

   Um diesem Übelstande abzuhelfen, ist es auch bekannt, als Klärmittel Aluminium- oder eisensalze mit einem gleichzeitigen Zusatz von Kalkwasser zu kombinieren, um eine stärkere Flockenbildung und raschere Reaktion zu erzielen.

 ihrer Schwerlöslichkeit bedarf der Zusatz der kohlensauren Magnesia keiner besonderen Vorrichtung, da dieselbe auch in   fester Form dem Wasser zugeführt   werden kann, wobei vom Wasser nur die zur Umsetzung mit Aluminiumsulfat erforderlichen   geringen Mengen   rasch aufgelöst werden. Die Verwendung von kohlensaurer Magnesia ist auch hygienisch vollkommen einwandfrei. da diese auch einen natürlichen Bestandteil des Wassers bildet, und man hat auf diese Weise

  Process for clarifying water.



   In the known clarification of the water with sulphate of alumina, such as those used for drinking water as well as for industrial purposes in quick filter systems, there is the disadvantage that with waters that have only a low temporary hardness and this is very important for the surface waters in question This is often the case - there is insufficient floc formation to produce such amounts, especially when the water has a large sludge content, that it is able to pull the sludge to the ground. In addition, the reaction occurs only slowly if the temporary hardness of the water is low, and so large and expensive pre-treatment plants have been required up to now.

   In order to remedy this disadvantage, it is also known to combine aluminum or iron salts as a clarifying agent with the simultaneous addition of lime water in order to achieve stronger flocculation and faster reaction.
 EMI1.1
 The addition of carbonate magnesia does not require any special device because of its poor solubility, since it can also be added to water in solid form, only the small amounts of water required for reaction with aluminum sulfate being rapidly dissolved. The use of carbonate magnesia is also perfectly hygienic. since this is also a natural part of the water, and you have that way

   PATENT CLAIMS: l. Process for clarifying and decolorizing water. characterized in that the latter is fed in addition to the aluminum salts, iron salts or dg!, carbonic acid magnesia known as clarifying agents, depending on the nature of the water some time before or after the feed of the reaction salts or simultaneously with part of the latter, while the rest is fed later.
