HORIZONTAL VACUUM FILTERS

HORIZONTAL VACUUM FILTERS are designed and constructed to reach high efficiencies for the filtration of slurry with heavy solid content. They are available in two main versions.

HORIZONTAL VACUUM BELT FILTER

 

 

 

 

 

 

 

 

One type (HVBF – Horizontal Vacuum Belt Filter) is equipped with a special reinforced rubber belt with draining grooves supporting the filtration cloth.
The belt and the cloth are simultaneously driven continuously.

HVBF is normally used with high capacities, heavy solids and large filtration surfaces.

HORIZONTAL VACUUM CLOTH FILTER

 

 

 

 

 

 

 

 

The other type (HVCF – Horizontal Vacuum Cloth Filter) is generally used for smaller filtration surfaces and only requires the filtration cloth without any rubber support. The cloth is driven intermittently.

HVCF is generally used for smaller flow rates and surfaces with lighter solids content.

  • High operational flexibility
  • Easy maintenance and low related costs
  • High washing efficiency
  • Separation of main water from washing water
  • Cake thickness, vacuum rate and belt speed may be easily and independently varied to get the best results
  • Partial or complete protective hoods can be provided
  • Steam drying available
  • Construction in a wide range of sizes from 0.1 m2 pilot lab units up to 150 m2 larger production systems

Tecniplant’s LAB will test the products and give the best solution in order to provide the right operational system.
Vacuum Belt Filter pilot units are also available in order to run on-site tests.
