Gravity Belt Thickener KomlineSanderson

A Gravity Belt Thickener employs gravity drainage through a filter belt to thicken polymer conditioned sludge prior to digestion mechanical dewatering or trucking to a land application site or disposal site Dilute sludge typically 05 to 10 is introduced at the feed end of a horizontal filter belt

Gravity Belt Thickener Belt Filter Press Sludge

Gravity belt thickeners are primarily used for sludge volume reduction prior to digestion dewatering or disposal They are a continuously operating machine which thicken sludge by gravity on a revolving porous filter belt They generally produce a pumpable thickened sludge

Sludge Thickening an overview ScienceDirect Topics

Tomasz Kamizela Mariusz Kowalczyk in Industrial and Municipal Sludge 2019 42 Gravitational thickening Gravitational thickening occurs through the sedimentation of sludge particles and their compression with gravity Cywiński et al 1972The sedimentation of sludge particles occurs due to the difference in specific weight of liquids and sludge particles whose specific weight is from 1

Belt Filter Press Sebright Products Inc

While many Belt Filter Press designs place these support grids too far apart 610 inches and on some the supports are also are too wide and block the drainage of liquids from the filter belt However Bright’s superior design places ½ inch wide UHMW plastic strips on 25inch centers
