gekehrten Wand perforierten Kugel-oder Pyramidenstutz, welcher mit einem mit ihm verbundenen Filtertuch überzogen ist.
Der Arbeitsvorgang der beschriebenen Apparates ist folgender : Durch das im Saugraumes und den Zellen z von der Pumpe hergestellte Vakuum legt sich auf die in den Schlamm tauchenden Zellen nasser Schlamm an und bildet sich zufolge der starken Flüssigkeitsentziehung bereits während der Rotation der Zellen innerhalb des Schlammbehälters eine ziemlich zähe Schlammschichte um dieselben.
Die abfiltrierte, in die Zellen eintretende Flüssigkeit läuft infolge des durch die kegel-oder

Die Hohlkörper R verhindern ein weiteres Absaugen und tritt in dem Augenblicke, in welchem die vorüberrotierenden Zellenöffnungen mit der Bohrunge für die Pressluftzuführung koinzidieren, Pressluft in die betreffende Zelle ein, welche die auf der

abgeworfene Zellen weder mit der Pressluftzuführung, noch mit dem Saugraum in Verbindung. wodurch bei eventuellem Schwanken des Schlammspiegels im Schlammreservoir das Vakuum im Saugraum nicht beeinträchtigt werden kann.
Die Vorteile dieses Verfahrens und des hiezu konstruierten Apparates sind folgende : 1. Der Aufwand an mechanischer Kraft ist ein äusserst geringer ; 2. der Betrieb ist ein kontinuierlicher und in sanitärer Beziehung einwandfrei ; 3. das Filtrat ist vollkommen von suspendierten Stossen frei und klar ; 4. die Bedienung und überwackung durch menschliches Personale reduziert sich

inverted wall perforated spherical or pyramid socket, which is covered with a filter cloth connected to it.
The working process of the apparatus described is as follows: The vacuum created in the suction chamber and the cells z by the pump is applied to the cells immersed in the sludge and, due to the strong extraction of liquid, a sludge forms within the sludge container as the cells rotate rather tough layers of mud around them.
The filtered liquid entering the cells runs through the cone or

As the rotation progresses, the cells, which are covered with viscous mud, gradually emerge from the mud bed and continue to rotate, always releasing liquid, until they reach the hollow

Sludge layers Dry cracks through which outside air is sucked in, which carries along the liquid particles still present in the sludge layer.
The hollow body R prevent further suction and occurs at the moment in which the cell openings rotating past coincide with the bore for the compressed air supply, compressed air into the cell in question, which the on the

discarded cells neither with the compressed air supply nor with the suction chamber in connection. so that if the sludge level in the sludge reservoir fluctuates, the vacuum in the suction chamber cannot be impaired.
The advantages of this method and the apparatus constructed for it are as follows: 1. The expenditure of mechanical force is extremely low; 2. Operation is continuous and flawless in sanitary terms; 3. The filtrate is completely free and clear from suspended impacts; 4. Operation and surveillance by human personnel is reduced
