What is a Drum Filter

What is a Drum Filter


A drum filter is a large, cylindrical machine typically used in applications to filter liquids carrying high concentrations of suspended solids. The rotating drum filter functions by drawing water through its external filter surface into its interior space by means of an internal vacuum. Suspended solids in the water are trapped on the surface of the drum and the filtered water is then pumped away. Drum filters may utilize removable screen type filter panels or have a sieve pattern of holes in their surfaces for use with a filter aid coating. Drum filters feature a minimum of moving parts and are cheap to operate and maintain.


What’s it advantages :

  • The drum filter is a continuous and automatic operation, so the operating cost is low.
  • The variation of the drum speed rotating can be used to control the cake thickness.
  • The process can be easily modified (pre-coating filter process).
  • Can produce relatively clean product by adding a showering device.


The drum filter is very effective at separating heavy, dense suspensions and can be cost effective, so has been used for many years in commercial fish farms due to the simplicity of the systems.
