  • Case study - Filtration for Alcan (France) swarf recovery at an aluminium billet plant

    In 1998 this Glosfume ceramic filter system was originally installed at British Aluminium plant in the UK to filter oily fumes from an induction furnace smelting oily swarf recovered from billet sawing. The filter is injected with 2C talc before being recycled back to the inlet ducting. At a pre-set time, the talc is discharged to a collection drum and the cycle is repeated. During 2006 British ...

  • Comparison of the water purification efficiency of two different flocculation-sediment-filtration (FSF) processes in Chaohu Lake in China

    A novel biofilter (BF) with the potential to improve pollutant removal when used as a substitute for sand filters in water purification processes is presented. To investigate BF's pollutant removal performance, a flocculation-sediment-biofiltration (FSBF) process was compared with a flocculation-sediment-sand filtration (FSSF) process on a lab scale, with water collected from Chaohu Lake. The ...
