The BHS rotary pressure filter (type RPF) is a continuously operating filter for pressure filtration, allowing gas-tight cake treatment in several separate process steps. The cake can be discharged under atmospheric conditions.
The rotary pressure filter makes a large number of process steps possible during one drum revolution. After the suspension has been separated into filtrate and filter cake, the rotary pressure filter additionally enables the following operations:
All process steps are performed in separate segment zones inside the filter. This allows filtrates and other fluids to be drained off separately.
