Abstract
In order to achieve improved collection of sludge in a settling basin, without employing moving parts, a collecting trough is provided, this trough being open at the top and bounded on the sides by horizontal overflow-weirs and being intended to rest on the bottom of the basin. A line, located level with the bottom of the collecting trough, issues from the trough and runs to a suction pump. The trough is covered by a hood which widens towards the bottom and leaves an unobstructed interspace between itself and the overflow-weirs, this hood possessing openings which lie at a lower level than the overflow-weirs.

A sludge collector for use in a settling basin, and comprising:
- a suction pump;
- a collecting trough open at its top;
- horizontal overflow-weirs bounding the sides of the collecting trough and being intended to rest on the bottom of the settling basin;
- a line level with the bottom of the collecting trough, issuing from the trough and running to the suction side of the suction pump;
- a hood covering the trough, the hood widening towards its bottom and leaving an unobstructed interspace between itself and the overflow-weirs, this hood having apertures defined therein which lie at a lower level than the overflow-weirs;
- the suction pump being in the form of a mammoth pump which is operated by means of compressed air and comprises a chamber and a line emerging from the chamber, the line emerging from the collecting trough opening into a lift pipe of the mammoth pump;
- a compressed air distribution-head communicating with the chamber and a compressed air supply line connected to the distribution head;
- tabs adjoining the overflow-weirs, said tabs having free lower edges and pointing obliquely downwards and away from the collecting trough and forming a chamber open in the downward direction, between themselves and the side walls of the collecting chamber;
- at least one compressed air supply line, issuing from the compressed air distribution-head opening into this chamber, and the free, lower edges of the tabs being located higher than the openings formed in the hood.
