Die bisherigen Vorschläge zum Sterilisiren von Trinkwasser durch Natriumsuperoxyd sind für eine praktische Verwendung nicht geeignet. Wichtig ist, dafs vor dem Gebrauch als Trinkwasser das Natriumsuperoxyd paralysirt werde, denn sonst ist das behandelte Wasser nicht nur ungeniefsbar, sondern geradezu schädlich. Der bekannte Zusatz von Citronensäure bald nach dem Zusatz von Superoxyd ist deshalb nicht zweckmäfsig, weil dann wieder das Wasser für Bakterien empfänglich wird und auch des Geschmackes wegen sich nicht zum unmittelbaren Genufs eignet.The previous proposals for sterilizing drinking water by sodium peroxide are not suitable for practical use. It is important that before using it as drinking water the sodium peroxide will be paralyzed, for otherwise the treated water is not only inaccessible, but downright harmful. The well-known addition of citric acid soon after the addition of superoxide is therefore not expedient, because then again that Water is susceptible to bacteria and also not because of the taste suitable for immediate enjoyment.
Zweck des den Gegenstand der Erfindung bildenden Verfahrens ist nun die Herstellung genufsfähigen, keimfreien Trinkwassers.The purpose of the process forming the subject of the invention is now production safe, germ-free drinking water.
Das Wasser wird nach dem Zusatz einer bestimmten, möglichst geringen Menge eines Alkalisuperoxydes, z. B. Natriumsuperoxyd, und einer geringen Menge Chlorcalcium mindestens ι Stunde der Ruhe überlassen. Nach dieser Zeit sind sämmtliche parasitären, die Infectionskrankheiten erzeugenden Bakterien getödtet. Um das Wasser geniefsbar zu machen, braucht es nunmehr nur noch mit Kohlensäure behandelt zu werden. Durch den geringen Chlorcalciumzusatz erreicht man gleichzeitig den Vortheil, dafs das sich bildende Calciumoxydhydrat im Wasser einen etwaige Verunreinigungen ausfällenden Niederschlag bildet. Um ferner das Wasser bis kurz vor seiner Verwendung steril zu halten, kann man die zur Paralysirung der Superoxyde dienende, in bekannter Weise zuzusetzende Kohlensäure erst im letzten Augenblick zuführen. Zu diesem Zweck richtet man den Zapfhahn des Behälters, in welchem das Wasser sterilisirt und aufbewahrt wird, so ein, dafs er erst in dem Augenblick, wo das Wasser zum Ausflufs gelangt, Kohlensäure zuströmen läfst, die durch eine besondere Vorrichtung zu inniger Vermischung mit dem Wasser gebracht wird.The water becomes after the addition of a certain, as small as possible amount of a Alkali peroxide, e.g. B. sodium peroxide, and a small amount of calcium chloride at least Leave to rest for an hour. After this time all are parasitic, infectious diseases producing bacteria killed. In order to make the water palatable, it now only needs to be treated with carbonic acid to become. By adding a small amount of calcium chloride one achieves at the same time the advantage that the calcium oxide hydrate which forms in the water is a possible impurity precipitating precipitate forms. To keep the water until just before its use The one used to paralyze the superoxides can be kept sterile in a well-known manner Only add the carbon dioxide to be added at the last moment. To do this, turn the tank's tap, in which the water is sterilized and kept, so that it is only in that The moment when the water reaches the outflow, carbonic acid flows in and flows through it a special device is brought into intimate mixing with the water.
Nach dem beschriebenen Verfahren erhält man ein äufserst schmackhaftes, erfrischendes und zuträgliches Wasser, das sich in seiner Zusammensetzung, im Geschmack und sonstigen Eigenschaften den schwachen, natürlichen Säuerlingen zur Seite stellen läfst.The process described gives an extremely tasty, refreshing one and wholesome water, which is different in its composition, taste and other Properties of the weak, natural sourlings can be put to one side.
