Pressure plate filter (PF)

Recovery of clear filtrates

The BHS 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 process steps are carried out under pressure. Cake discharge is accomplished by vibration of the filter elements.

The filter is used primarily for cake-forming solid-liquid separation of suspensions with a low solids content that are moderately or very difficult to filter. It is also suitable for adsorptive filtration (as a deep bed or precoat filter). The BHS pressure plate filter is frequently used for clarifying filtration. The plate filter is a compact unit, operates fully automatically and allows high throughput rates. Vibration discharge requires very little energy consumption. Furthermore, there is no longer any need for a complicated and sealed shaft system that traverses the pressure vessel.

Choosing a Fine-Particle Filtration System

Filtration technology has advanced to meet the demand to remove small particles at low concentrations. When designed ocrrectly, a candle filter or a pressure plate filter may be a more-efficient replacement for a traditional filtration scheme.

Framework for Selecting Solid-Liquid Filtration Technologies for Particle Fines Removal

In the manufacturing of chemicals, petrochemicals, pharmaceuticals, etc., after the initial mixing-reactions, there is always the necessity to remove the mother liquor from the process slurry. In some cases, the liquid is the valuable component, some cases it is the solids and in other cases it is both compounds. The nature of the requirements determines the type of equipment needed for the separation process. This paper provides an overview of separation equipment and then continues with a detailed view of technologies that can remove – recover small particle fines.
