Belt filter press, also known as belt filter, is a kind of industrial machine used for solid-liquid separation processes. It is widely used for sludge thickening and dewatering in many industries, such as food (vegetable oil, sugar, juice, etc.), mining (tailing sewage), washing plant (sand, coal, etc.), chemistry (gas cleaning,etc.), wastewater treatment plants, refining, electroplating, power plant (sludge), chemical,
How does belt filter press work: The main dehydration section of belt filter press is divided into gravity dehydration section, squeeze dehydrator section, and concentrated dehydration section. The concentrated sludge in the sedimentation tank is mixed with the agent through the flocculation system to make the sludge flocculate into blocks and enter the belt filter press for filter press treatment. The sludge first passes through the concentrated gravity dehydration, and then enters the gravity dehydration zone for dehydration. The squeezing dehydration is carried out through the mesh belt and the dehydration roller, and finally the sludge forms a filter cake and is discharged. 
According to different structure, our belt filter press include drum concentrating belt filter press, filter belt type belt filter press, heavy carbon steel belt filter press. We will provide customized solution for you according to your specific needs.


  • In the transition dewatering zone, this machine uses a large diameter circular arc dewatering technology which is specially designed. It can make the filter belt pressure gradually increase and effectively prevent the phenomenon of running mud. Therefore, this machine can greatly improve the treatment of sludge.
  • It is equipped with a concentration pre-processing equipment, which has a better flocculation effect and reduces operating costs.
  • The gravity dewatering zone has an advanced distribution device to spread the material evenly and extend the life of the filter cloth.
  • Better dehydration effect, large processing capacity, energy saving.
  • Different filter bands can be selected based on various materials, with high precision. According to the different feed concentration, the types of belt filter press to choose from.
  • Belt filter pressr put concentration, press, dehydration function in one machine. It has the target consummation pressure filtration dehydration system because it is a two level preloading. With better dewatering effect and high efficiency,it is well received by the market. More projects arond the world, such as Pakistan, Indonesia, Singapore, Thailand, Phillipine, Malaysia, Sri Lanka, Saudi Arabic, Turkey, South Africa, Kenya, Nigeria, etc. We also have other types of filter presses for slurry processing.
