As sludge is deposited on the belt filter press, they first pass through a gravity section, where water is drained by way of the natural flow of gravity pulling the water through the perforated belt.  Sludge is moved and rolled by multiple rows of plows that force and turn the sludge in order to extract the most water from the mixture.

Then the sludge is  conveyed into a wedge zone, where it is progressively compressed and extracted more water as it is moved through the zone.

The final section is a series of rollers through which the sludge is compressed in order to maximize the drying effect.

Features:

1 Super dehydrating effect: Belt filter press has a long gravity dewatering zone and a wedge-shaped dehydration area, ensuring that materials are fully dehydrated and will not overflow in the press area. Also, the anti-flushing devices on the filter belts guarantee belts’ dewatering effects.

2 Large capacity of disposal: Belt filter press works continuously, thus creates a high working efficiency.

3 Steady operation: Belt filter press adopts belt correction system. Filter belts are adjusted by tension in the operation, ensuring that filter belts run normally.

4 Labor-saving and easy for operation: Belt filter press uses PLC program control and DCS remote interface. It has a high degree of automation.

5 Long service lifetime: advanced distributing device in the gravity dewatering zone can distribute materials equally, which will extend belts's service lifetime.

6 Double filter belt: Circulate by two belts at top and bottom for fast and high rate dewatering.  Adjustable operating velocity from 1 m3/min to 9 m3/min.

7 Washing water can be reused and is adjustable to save up to 50% of washing water.
