Sludge removers which as well as being well suited for cleaning sedimentation tanks or fish ponds also can clean concrete fish ponds and raceways. The photo shows an Wintec Polska sludge mover in a sedimentation basin. The machinery is also very well suited for cleaning concrete fish ponds and raceways. The plant is a frame construction floating on pontoons. The frame has two lengthwise rails for a submerged sludge pump running from one end the other.
The plant is drawn stepwise by chain wheels from one end of the basin to the other. The position is kept long enough so that the pump can move from end to end sucking away the sludge.
