Candle filter The candle filter of type CF is a filter that operates in a discontinuous manner. The candle-shaped filter elements are arranged vertically in a pressure vessel. The process steps typically performed with this unit are filtration, washing, drying and discharge. All these steps take place under pressure. The candle filter is used for the clarification of liquids with a low solids content. It is a compact unit, operates fully automatically and enables high throughput rates, dry cake discharge and a wide range of cake treatment options. Benefits at a glance: • High throughput rates • Fully automatic operation • Low investment costs • GMP design is possible (pharmaceutical & food industry) • Modular turnkey system concepts Versatile technology solutions In order to meet the respective process engineering requirements, the filter cake can be treated in many ways. It can be washed or slurried once or several times. To achieve further dehumidification of the filter cake, it is possible to pass air, nitrogen or other gases through it. If necessary, precoat filtration can be performed using filter aids. Fully automatic operation The candle filter works fully automatically. At the end of a process cycle, the filter cake is separated from the candle surface by means of a blow-back blast and discharged. Then, the next cycle begins. Safe pressure filtration system The entire filtration process takes place under pressure – up to a differential pressure of 10 bar g – in a closed, gas-tight system. This enables the use of BHS candle filters even under stringent safety or hygienic requirements. Products can also be processed in an inert or sterile atmosphere.
