- Simple design
- Long service life
- High reliability
Fields of use:
- mainly for dewatering suspensions that are medium difficult and / or difficult to filter
- when cake washing is not required
This is the most commonly used type of filer presses.
The working area consists of a filtration chamber created by mutual shifting of two adjacent filtration plates to each other. In the flat parts of the filter plate there are recesses with a drainage system. The total depth of recesses in both the adjacent plates determines the thickness of the final filtration cake. This usually ranges between 15 – 50 mm.
Suspension is usually fed via a central or a corner inlet, filtered liquid passes through the cloth and is drained by the drainage along the plate surface and via the drilled channels inside the plate out of the filter press.
The working pressure extends between 6 – 15 bar.
The plates and clothes are standardly made of polypropylene, another material can be chosen based on the character of filtered suspension.
