FP 500 belt filter press

The FP belt filter press squeezes sludge between two permeable belts. First, free moisture drains off by gravity in the gravity drainage section, then the belt with the sludge passes over a system of rollers and the pressure on the layer builds up gradually.

A narrow belt sets a small throughput and a compact frame, so the designs in this subgroup are installed where dewatering is given not a dedicated hall but a corner of a room: local treatment facilities, separate production areas, farms.

Operation here is more often per-shift rather than round-the-clock: sludge accumulates slowly, and the press is started as it builds up. Requirements for sludge conditioning do not depend on belt width — flocculant is prepared and dosed the same way as on the larger designs.

FP 500 design: capacity by dry solids 100–120 kg/h, drive power 0.75 kW, working belt width 500 mm, water flow rate 6.2 m³/h.

The smallest unit in the line by capacity by dry solids: 100–120 kg/h against 200–203 kg/h on FP 1000A. Water flow rate 6.2 m³/h against 11.2 m³/h on FP 1000A. Drive power 0.75 kW against 1.1 kW on FP 1000A. Mixer power 0.25 kW — the same as on FP 1000A.

One step up by capacity by dry solids — FP 1000A: working belt width 1000 mm instead of 500 mm, belt speed 1.04–4.5 m/min instead of 1.57–5.51 m/min.
