Plate filters and filters

1. Plate filters according to our design or your specifications

Deprest has a long tradition in the fabrication of plate filters.

The pressure plate filter is a batch-operated filter with plate-shaped filter elements arranged one above the other inside a pressure vessel. The filter cake builds up on the filter plates. The clear filtrate is discharged inwards through the hollow shaft. All the process steps are carried out under pressure.

The filter is used primarily for cake-forming solid-liquid separation of suspensions with a low solids content that are moderately or extremely difficult to filter. It is also suitable for absorptive filtration.

What distinguishes our plate filters is the possibility of retightening the filter plates from below during the filter process itself, without releasing the pressure of having to interrupt the process.

Plate filters are usually manufactured in stainless steel (304 or 316), but can also be produced in highly-alloyed materials such as Hastelloy. The desired level of finish will depend on the project, but a very fine finish, as required for the pharmaceutical industry, for example, is possible.

2. Other filters to your specifications

Apart from the plate filters, Deprest also will manufacture a variety of filters to your specifications, whether or not you require them pressurised, of course.
