ABSTRACT:
A continually operating automatic sludge suction unit for use in withdrawing sludge from the bottom of a primarily rectangular or square basin. The unit is controlled for zigzag movement on the surface of liquid in the basin by means of cables and cable guides, and a pump suspended in a cable from a float included in the unit automatically follows any irregularities at the bottom of the basin. A counterweight is included for ensuring smooth movement of the unit on said surface.
