Belt filter press is a device that achieves solid-liquid separation through pressurized gravity dehydration. It is a device used to filter water from sludge and ultimately produce non-liquid filter cake.The belt filter press dehydration process can be divided into four important stages: pretreatment, gravity dehydration, wedge zone pre-pressing dehydration and squeezing dehydration.



Process Flow 

I.Gravity dehydration zone: After the slurry is pumped into the slurry mixing tank and mixed with the polymer coagulant, the fine suspended particles in the slurry are bridged by the polymer coagulant to form large particles in the form of latex(floc). The method overflows from the upper end of the mixing tank and flows into the subsequent ppress dehydration operation.
II.Pre-pressure dehydration zone:
After gravity dehydration of slurry, the fluidity is obviously worse, but it is still difficult to meet the requirements of sludge fluidity in the press dewatering section. Therefore, a wedge-shaped pre-pressing dehydration is added between the sludge dewatering section and the gravity dewatering section. In this section, the sludge is dewatered by slight squeezing to remove the free water on its surface, and its fluidity is almost completely lost. This ensures that the sludge will not be squeezed out in the dewatering section under normal conditions. Create conditions for pressing dehydration
III.Pressurized dehydration zone:
When the slurry leaves the wedge-shaped pre-pressing dehydration zone, it enters the pressure zone. The mud is squeezed in this zone. The pressure along the running direction of the filter belt increases as the diameter of the squeeze roll decreases. At this time, the mud cake is basically formed, and the water content of the mud cake can be reduced to a minimum after high pressure in the high pressure zone at the end of the pressure.

Technical data
There are several models you can choose.

Application Range

Belt filter press are mainly used in municipal sewage, textile printing and dyeing, electroplating, papermaking, leather, brewing, food processing, petrochemical, chemical, metallurgy, pharmaceutical, ceramics sludge dehydration treatment, slaughter, food, wine making, coal washing, sewage treatment and sludge dewatering in industries such as factories and environmental protection projects. It is also suitable for the solid separation or liquid leaching process of industrial production, and it is an ideal equipment for environmental treatment and resource recovery.
