belt filter press high pressure zone

Filtration principle using belt filters - Degremont®

In belt filters, pressing does not take place in an enclosed compartment: therefore, it is the sludge that, under the pressure it can tolerate as it travels around, provides lateral sealing; if this pressure is too high, the sludge layer cohesion is destroyed and there will be squeezing out, with partially dewatered sludge leaving the filtration area.

Belt Filter Presses Design Information Report

High pressure/tension presses are more com- plex and require more maintenance than lower pressure machines. When the high solids cake produced on these devices is not needed, the added maintenance and additional costs are not worthwhile. 2. Increased maintenance, reduced bearing life and increased corrosion and cloth blinding can occur in belt presses when used to dewater sludge conditioned ...

Siemens Sernagiotto belt presses have three zones: first the gravity drainage zone, where the filter belt acts as a simple straining device; second the wedge zone, where a gradual increase in pressure is applied to the sandwiched cake between the two filter belts; and finally a high pressure zone which can consist of either surface pressure "S" rolls, or high pressure press nip rolls.

Under the gravity, free water would fall on the tray, and the rest sludge would be nipped between two belts. Then it would further goes to the wedge zone for pre-filtration, and then to low pressure zone and high pressure zone through the decreasing diameter rolls. Under the extrusion and shearing force, the solid and liquid is separated.
