Gravity thickener DrainBelt

Belt thickener for highly efficient sludge thickening The trough-shaped design of the feed reactor ensures the optimal conditioning and uniform distribution of the sludge over the full width of the filter belt. 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. The HUBER Belt Thickener DrainBelt guarantees minimum operating costs: Very low coagulant agent demand Efficient nozzle feeding of coagulant agent Variable mixing energy Flow-optimised flocculation reactor Gentle sludge treatment for minimum shear stress Maximum filtrate quality A variety of filter belt qualities Separate collection of clear filtrate and filter wash water Optional return of wash water No return of polluted filtrate into clear filtrate Maximum thickening degree Long thickening zone, low belt velocity Adjustable pillow blocks for sludge restacking Optional ramp for increased thickening degrees Minimim maintenance costs Long filter lifetimes Easy maintenance due to centrally positioned inspection openings Fouling-resistant roller bearing for a virtually unlimited life
