 das zu klärende Wasser eintritt, macht sich der Umstand unangenehm bemerkbar, dass der abgeschiedene Schlamm nicht ohne   Betriebsstörung   entfernt werden kann, weil er entweder gar nicht oder nur nur   bei ausserordentlich   starker Neigung der Sohle auf dieser   abwärts   gleitet.

   Dies rührt in den meisten Fällen-ausser von der Adhäsion   an der Gleitfläche-     hauptsächlich   daher, dass der Unterschied zwischen dem spezifischen Gewicht des Schlammes und demjenigen der Flüssigkeit, worauf die Sedimentierung oder Aufbereitung beruht, zu

  Device for removing sludge from settling basins.
 EMI1.1
 If the water to be clarified enters, the fact that the separated sludge cannot be removed without operating disruptions becomes unpleasant because it either does not slide down at all or only when the sole is extremely inclined.

   In most cases - apart from the adhesion to the sliding surface - this is mainly due to the difference between the specific weight of the sludge and that of the liquid on which the sedimentation or processing is based
 EMI1.2
 In the embodiment shown in FIG. 1, one or more rows are arranged above one or more depressions, preferably running in the longitudinal direction of the hedges.
 EMI1.3
 wishes is. In their deepest position, which is the next layer, these slightly overlapping plates form an uninterrupted cover for the longitudinal recess or the lower part of the hedge area.



   Depending on the relative amount, the specific weight or other physical properties of the mud and depending on the size of the angle of inclination of the sole recess, what ratios for the speed of the self-movement of the mud
 EMI1.4
 
Instead of the system of small plates, depending on the size of the basin or the type of sludge, etc., fully or partially movable channel parts of any shape can be used. as indicated in Figs. 2 and 3 can be used.
