Low Cost Gravity Belt Filter Press Thickener for Inorganic Sludge Treatment

BOEEP low cost belt filter press thickener uses the principle of gravity to concentrate sludge, which can be used for inorganic sludge dehydration.
  • DN2.5
  • DN

Product Introduction

DN type gravity belt thickener is an automatic sludge thickener which can replace the traditional sludge concentrated tank. The sludge from the secondary sedimentation tank can be condensed rapidly and continuously. After condensed and seperated, the sludge concentration can be adjusted between 90% and 96% stably. There are many advantages after making use of this device, such as no need of concentrated tank, small footprint and less cost. This device adopt the developed technology and design, which is able to meet the different requirements in various industries.

Structure & Working Principle

The design and manufacture of the belt filter press thickener can adapt to the harsh working environment of high temperature and 100% humidity in the concentrator room, and ensure the stable and reliable operation of the euipment.

The belt filter press thickener runs smoothly and normally, no impact, vibration and abnormal sound. All parts are tested and qualified before assembling.

The flocculated material is uniformly sent to the filter belt through the fabric mechanism to carry on the gravity concentration. In this section, there is a long horizontal movement and a small angle rising, and the material moves with the filter belt. Under the action of gravity, free water is separated from the floc and removed most free water in the material.

structure of belt filter press thickner


1-Continuous operation, large capacity, low power consumption and low noise which makes excellent operating environment.

2-The main drive speed regulation mode: frequency conversion.

3-Reasonable gas path design and high quality pneumatic components ensure the stable operation, improve the service life and reduce maintenance costs.

4-The filter belt is tightened by pneumatic way, with convenient operation and low investment cost.

5-The belt is corrected by pneumatic self correcting, and the filter is rectified in real time by induction switch, which makes the equipment stable and reliable.
