Belt Press Filter. In a belt press filter, pressure can be achieved up to 12 bars. It consists of two endless belts and several rolls. The slurry is first flocculated before dewatering. The filter cake from a rotary vacuum filter can be further reduced by 5%–6% moisture in the belt press filter (Bragg, 1983).

High-pressure air or water automatically inflates the diaphragm located at the top of each chamber, reducing the chamber volume and squeezing the solids to remove more filtrate. The solids filtration process and tightly woven filter cloth produces exceptionally clear filtrate, while the high pressure maximizes filtration efficiency.

The low-pressure zone prepares the biosolids by forming a firm cake which can withstand the forces of the high pressure zone. In the high-pressure zone, forces are exerted on the solids by the movement of the upper and lower belts as they move over and under a series of rollers of decreasing diameter. Some belt filter press models separate from ...

The filter press is one of the oldest mechanical dewatering devices. FAURE EQUIPEMENTS first used filter presses in the ceramic industry in order to produce ceramic pastes. The first filter press was made by FAURE EQUIPEMENTS in 1890. Filter presses are also used in chemical, sugar and brewery industries since a long time.

Constructed of stainless steel and high-grade plastics, belt filter presses are extremely resistant to fouling and corrosion. While many competitive dewatering systems employ linear designs, these systems are built with their dewatering zones stacked vertically, so equipment takes up less floor space.

Two belt filter press units were selected for this project, to dewater coal tailings material. The belt press filters were selected due to a low capital cost and high tonnage throughput, relative to other technologies suitable for this application. The units were factory run tested before being shipped to site as fully assembled modules.
