Jiangsu sewage treatment filter press - Plate and frame filter press

Jiangsu sewage treatment filter pressThe processing capacity is relatively large, especially suitable for large-scale slurry dewatering treatment enterprises such as washing machine stone sand mud dewatering, sand field wastewater sludge dewatering, construction mud dewatering, pile driving mud dewatering, iron ore tail mud dewatering, copper ore tail mud dewatering, lead-zinc ore tail mud dewatering, fluorite ore tail mud dewatering, bauxite tail mud, rare earth ore tail mud, and mineral processing wastewater.

Jiangsu sewage treatment filter pressThe filtering and dehydration functions are divided into three steps:
1. Gravity dehydration zone
The sludge from the wastewater treatment plant is pumped into the sludge mixing tank and mixed with a high molecular weight flocculant, causing the small suspended particles in the sludge to form larger latex like particles through the bridging effect of the high molecular weight flocculant. Then, they overflow from the upper end of the mixing tank into the subsequent pressing and dewatering operation by gravity flow.
2. Pressure dehydration zone
After the sludge enters the pressure dewatering zone from the gravity dewatering zone, the upper and lower filter cloths gradually squeeze the sludge for dewatering.
3. Pressurized dehydration zone
The sludge moves into the pressurized dewatering zone with the filter cloth, and is arranged between six vertical rollers in a configuration where the roller diameter gradually decreases and the pressure gradually increases. With the shear force generated by the change of the upper and lower positions of the filter cloth between different rollers on the sludge, the capillary tubes in the sludge are combined with water pressure to produce a drier sludge cake.
