The Pressure Drum Filter (photo) consists of a fully opening pressure vessel with a fixed bumped boiler end on the drive side and a moveable cylindrical housing on the opposite side. Both parts are locked pressure tight by a snap closure. The continuously operating pressure drum filters are available in three designs: as single cell filters, multi-cell filters and multi-chamber filters. Systems are designed to handle 8 bars pressure difference and 240°C operating temperature, and have a filtration area of up to 60 m2. The drum velocity ranges from 0.1 to 10 rpm. Specific throughputs of up to 10,000 kg/m2 h are achieved for well-filterable products. The manufacturer says pressure drum filters can save considerable energy compared to that required for decanters, while also lowering investment and operating costs.
