Backflush Filters

Purest Liquids

The BOKELA Backflush Filter / Polishing Filter is an automatically operated pressure filter. It is used for the clarification / polishing filtration of high liquid flow rates with a low level of solid impurities (typical range: 100 – 300 mg/l). The filtration is performed at up to 5 bar in a pressure vessel equipped with special components. The filtered impurities are discharged from the filter cloth by a filtrate backflush and removed from the vessel as thickened sludge. The filtrate is nearly particle-free.
