Highly efficient pressure filtration and cake washing The BHS rotary pressure filter (type RPF) is a continuously operating filter for pressure filtration. It facilitates gas-tight cake handling in a series of separate process steps. Cake treatment can, for instance, comprise single- or multi-stage cake washing and subsequent cake drying. Cake discharge can take place at atmospheric pressure. Application scenarios cover a wide range of industries, including industrial chemicals, fine chemicals, the pharmaceutical industry and the food industry. Production of high-quality pearlescent pigments with the rotary pressure filter (RPF) BHS-Sonthofen rotary pressure filters have proven themselves in many applications. For example, Merck uses them around the clock to produce pearlescent pigments. Watch the video to find out how BHS filtration solutions give cars and cosmetics a shiny appearance. Versatile technology solutions The rotary pressure filter supports a broad range of process steps during a single rotation of the drum. After separating the suspension into filtrate and filter cake, the rotary pressure filter supports the following additional processes: single- or multi-stage cake washing, displacement washing, counter-current washing, circulation washing, slurrying, solvent exchange, steaming, extraction, as well as mechanical or thermal cake dehumidification. All process steps take place in separate segment zones within the filter. This makes it possible to separately discharge the filtrates or other substances.
