FP 1500A belt filter press

The mid-range FP designs run continuously: sludge moves as a flow, without the "fill chambers — open plates" cycle that a chamber filter press lives by. After the gravity section the belts form an S-shaped path, the wedge between the rollers presses the layer further, and cake is discharged at the outlet.

The belt width of this subgroup covers the main demand of municipal wastewater treatment plants and medium-sized industrial sites — petrochemicals, chemical fiber, pulp-and-paper and pharmaceutical production.

The press handles organic hydrophilic and inorganic hydrophobic materials equally well. Sludge is fed into the flocculant mixing unit, where flocs have time to form before reaching the belt. With a variable wastewater composition, the operating mode is adjusted by belt speed and reagent dose, without touching the mechanics.

FP 1500A design: capacity by dry solids 300–360 kg/h, drive power 1.1 kW, working belt width 1500 mm, water flow rate 16 m³/h.

By water flow rate it sits between FP 1000A (11.2 m³/h) and FP 1500B (17.6 m³/h): 16 m³/h. Capacity by dry solids 300–360 kg/h — the same as on FP 1500B. Mixer power 0.37 kW — the same as on FP 1500B. Working belt width 1500 mm — the same as on FP 1500B.
