he slurry is sandwiched between two tensioned porous belts, by passing those belts through a serpentine of decreasing diameter rollers. Water is then removed from the slurry and a solid material
is produced.
How does belt filter press work?
(1) Thickener dehydration: chemical pretreatment stage
The belt filter press has higher requirements for flocculation effect. This machine uses a unique dosing mixer to achieve rapid flocculation and achieve the best flocculation effect.
(2) Gravity dehydration: gravity concentration dehydration stage
The sludge is evenly fed into the mesh belt through the cloth bucket. The sludge runs forward with the filter belt. The free water flows into the water tank through the filter belt under the
action of its own weight. The main function is to remove the free water in the sludge, so that the fluidity of the sludge is reduced and ready for further extrusion.
(3) Low/medium pressure dewatering: wedge preloading dewatering stage
After gravity dewatering, it is still difficult to meet the sludge flowability requirements of the press dewatering section. After this stage of slight extrusion dewatering, the sludge is
smoothly pressed and dewatered.
(4) High pressure dehydration: the depressurization stage of the clamp press
The filter cake is repeatedly pressed and sheared around the press roll by the upper and lower filter belts. A large amount of capillary action water is removed to gradually reduce the moisture
of the mud cake.
Features
Belt press has an easily adjustable and variable wedge compression zone that maximizes process rate and performance.
Suitable for all types of organic sludge and inorganic mud, municipal WWTP sludge, pulp &paper sludge, water plant sludge.
The belt press is constructed with a stainless steel structure and rollers, durable for more than 10 years .
Low power is needed to run the belt filter presses. With long term value and ease of operation.
Compact footprint, 4-stage dewatering and automated operation
Belt Press Applications
Belt filter presses are designed for dewatering applications where sludge is particulate, include various types of industrial wastewater sludge, such as sand-making mud, washed sand mud, mine
tailings, piling mud, river silt, etc. They are pumped to the deep cone thickener, the flocculant is added to the thickener tank, and the concentration of the sludge in the thickener is
increased by 60%-70% under flocculation and gravity precipitation. Then sent to the belt filter presses, under the action of a gravity zone, a wedge zone, and a pressure zone , the sludge cake
with water content of less than 20% is formed and the overflow clean water will be re-processing.
