Belt Filter Press 10–50 m³/h Sludge Dewatering System
The belt dewatering machine device is a high-duty wastewater treatment system designed for sludge thickening and dewatering in one unit. It is suitable for treating unconcentrated sludge such as A/O residual sludge in municipal and industrial wastewater plants. With a multi-roll pressing structure and high-pressure design, the system achieves high treatment capacity and lower moisture content, ensuring efficient solid-liquid separation and stable continuous operation.

Product introduction of Wastewater Belt Dewatering Machine
The belt filter sludge dewatering device, also known as a belt filter press or sludge dewatering system, is designed for efficient sludge concentration and dewatering without the need for a separate thickening tank.
This equipment integrates sludge thickening, pressing, and dewatering into a continuous process. It is particularly suitable for low-concentration sludge streams, improving sludge handling efficiency and reducing overall treatment costs.
The enclosed structure design enhances operational safety while minimizing odor and simplifying maintenance.
Working principle
The belt filter sludge dewatering device operates through a continuous filtration and pressing process.
Sludge first enters the gravity thickening zone, where free water is removed through filtration. It then passes through a wedge-shaped pre-dewatering zone before entering the high-pressure pressing section.
Multiple press rollers apply increasing pressure to the sludge, removing bound water and forming a low-moisture sludge cake. The filter belt continuously transports the sludge through each stage, while a spray washing system cleans the belt surface for stable operation.
