Rubber belt filter (BFR)

High-volume filtration of sedimenting media

The BHS rubber belt filter (type BFR) is a continuously operating, horizontal vacuum belt filter used for the efficient separation of sedimenting (incl. abrasive) solids. The individual filtrates are kept entirely separate to avoid cross-contamination.

An endless filter cloth with a continuous movement serves as the filter medium. A rubber belt is used to support the filter medium. The rubber belt is provided with milled grooves for filtrate discharge; it runs on a roller conveyor and on wearing and sealing belts over a stationary vacuum box, where the filtrates are collected and discharged.

The filter cake forms on top of the belt and can undergo further treatment by washing (co-current or counter-current), steaming, extraction or vacuum drying. The wash filtrates can be recovered individually from each process step and further processed without any cross-contamination. The belt filter discharges the filter cake at the discharge roller. The cloth is cleaned as the belt travels back.

Besides the standard open-frame design, we can offer the following optional versions of the vacuum belt filter:

  • Closed hood over the entire filter
  • Materials for special applications
  • ATEX design

Framework for Selecting Solid-Liquid Filtration Technologies for Particle Fines Removal

In the manufacturing of chemicals, petrochemicals, pharmaceuticals, etc., after the initial mixing-reactions, there is always the necessity to remove the mother liquor from the process slurry. In some cases, the liquid is the valuable component, some cases it is the solids and in other cases it is both compounds. The nature of the requirements determines the type of equipment needed for the separation process. This paper provides an overview of separation equipment and then continues with a detailed view of technologies that can remove – recover small particle fines.
