Improved backwashing of filter candles
Last year, this company filed a patent for a new cake and precoat filter candle design. The target was to develop a support structure that is inexpensive to fabricate and that at the same time provides the lowest possible flow barrier, allowing for a backwash flow as high as possible throughout the total candle length. The CakeFil technology (photo) assures real process automation without interruption periods or any manual operation. The discharge functions either as slurry or, after an optional previous cake washing and drying step, as dry-to-the-touch discharge. Beside its precoat and cake-building technology, the company is also exhibiting its reliable backwash-filtering system for finest filtration of fluids for industry and for water treatment. The OptiFil and ViscoFil technologies ensure the highest process continuity at the lowest backwash quantities. Hall 7, Stand L12 — Lenzing Filtration, Lenzing, Austria
