![]() ![]() All solvent and gas streams can be recovered separately and reused in the process to minimize their consumption. After automatic cake discharge, the filter cloth is washed the clean filter cloth then re-enters the feeding / filtration zone thereby continuing the process. Low operation cost High capacity Superior flexibility. The Filter has a uniquely designed discharge system, which provides for atmospheric discharge from pressure filtration. the Dorr-Oliver Vacuum Drum Filter is a trusted solution for filtration and dewatering. Finally, the cake is dried by blowing hot or ambient-temperature gas through the cake. Multiple washing steps as well as solvent exchanges, steaming and extraction can also be accomplished. A brownstock washing set uses a series of filters through which the filtrate flows countercurrent to the brownstock being washed. Positive displacement washing or counter-current washing follows filtration. The technology is based upon a slowly rotating drum, less than 2 rpm, with individual cells containing the filter media and isolated process zones.įiltration is driven by pump pressure of up to 7 barg with a temperature range of 200° Celsius. 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. ![]()
