In the final stages, the sludge moves into the Wedge Zone, where it undergoes a gradual increase in pressure.Following this, the sludge enters the Maximum Pressure Zone, where it is tightly compressed between the main filter cloth and the secondary filter cloth lining the perforated cylinder. This ensures maximum dewatering efficiency and a high-quality sludge cake.

2/3 of the way through the zone. By curv-ing the wedge profile the top belt imme-diately pressurizes the cake making the entire length of the zone effective. In addi-tion, the spiral profile provides a gradual increase in pressure through the zone and forces an encapsulation of the cake to resist extrusion out the side. Model 3DP Belt Filter Press

Many belt filter press technologies contain a second pressure zone comprising a series of rollers through which the two belts pass with the sludge solids retained between them. The rollers in this high pressure zone apply tensioning (i.e. stretching) to the belts, exerting both shearing and compressive forces on the sludge which further release ...
