General Description

The BHS Rotary Pressure Filter is a continuously operating filter for pressure filtration, cake washing and drying of high solids slurries with full containment and automatic cake discharge. The technology is based upon a slowly rotating drum, less than 2 rpm, with individual cells containing the filter media and isolated process zones.

Filtration is driven by pump pressure of up to 7 barg with a temperature range of 200° Celsius. Positive displacement washing or counter-current washing follows filtration. Multiple washing steps as well as solvent exchanges, steaming and extraction can also be accomplished. Finally, the cake is dried by blowing hot or ambient-temperature gas through the cake.

The Filter has a uniquely designed discharge system, which provides for atmospheric discharge from pressure filtration. After automatic cake discharge, the filter cloth is washed; the clean filter cloth then re-enters the feeding / filtration zone thereby continuing the process. All solvent and gas streams can be recovered separately and reused in the process to minimize their consumption.
