Belt thickener for sludge treatment
The filter belt is guided horizontally by a drive and a tensioning roller. Via a feed chute positioned above the tensioning roller the sludge is smoothly fed onto the filter belt and transported towards the sludge discharge point by the slowly travelling filter belt. The sludge flocks are then gently settling on the rotating filter cloth and the water separated by flocculation drains off by gravity. The sludge cake is taken off the filter belt by a plastic doctor blade mounted on the drive roller.
