- Le filtre rotatif est une machine permettant de séparer un mélange solide-liquide. (fr)
- A Rotary Vacuum Filter Drum consists of a cylindrical filter membrane that is partly sub-merged in a slurry to be filtered. The inside of the drum is held lower than the ambient pressure. As the drum rotates through the slurry, the liquid is sucked through the membrane, leaving solids to cake on the membrane surface while the drum is submerged. A knife or blade is positioned to scrape the product from the surface. The technique is well suited to slurries, flocculated suspensions, and liquids with a high solid content, which could clog other forms of filter. It is common to pre-coated with a filter aid, typically of diatomaceous earth (DE) or Perlite. In some implementations, the knife also cuts off a small portion of the filter media to reveal a fresh media surface that will enter the liquid as the drum rotates. Such systems advance the knife automatically as the surface is removed. (en)
- I filtri a tamburo (in inglese rotary drum filter) sono delle apparecchiature impiegate per la filtrazione, ovvero la separazione di un solido in miscela con una fase eterogenea. Esistono due tipi di filtro a tamburo:
* filtro a tamburo tipo Oliver
* filtro a tamburo tipo Swenson. (it)
