Rotary Vacuum Drum Filters

Vacuum Drum Filters

The rotary vacuum drum filter was patented in 1872 and, since then, has been used extensively in the processing of chemicals, pharmaceuticals, cosmetics, and minerals. Compositech's rotary drum filter design provides reliable liquid/solid separation with minimum operator attention and maintenance requirements even in heavy duty, 24-hour continuous operation. Our rotary drum filter's ability to accommodate maximum hydraulic flows and a wide range of cycle times allows optimum cake formation in many different types of slurry.

Rotary Drum Filter Discharging

There are a variety of discharge options available for rotary drum filters. The discharge arrangements typically used by our customers are:

  • scraper discharge
  • belt discharge
  • roll discharge
  • precoat discharge

Drum Filters

In clarifying applications of rotary drum filters, very high filtrate clarity can be achieved with precoat discharge designs. For corrosive applications, Compositech offers thermoplastic rotary vacuum drum filters to provide dependable vacuum filtration at a substantially lower cost than machinery constructed of exotic metals. All components which contact corrosive agents are made of engineered plastics. The rotary drum filter is available totally enclosed for caustic chemical and mineral applications.
