CFP80 chamber filter press

The chamber filter press dewaters sludge using the pressure of the feed pump. Filter cloth is stretched over the plates and, when the pack is compressed, also acts as a seal, so a chamber forms between each pair of plates. Slurry enters through the central channel, filtrate is drained by the plates' drainage channels, and the solid phase remains in the chambers.

The smaller designs in the line are rated for sites with intermittent or small sludge output: local wastewater treatment facilities, individual workshops, wash bays and water treatment areas. Work goes in cycles, so sludge is usually accumulated in a receiving tank and pressed in batches rather than at the rate of inflow.

Moderate weight and a compact frame allow the press to be placed in an existing building, without a dedicated foundation. The site needs a passage along the pack for cake removal and room for a container; piping is limited to slurry and filtrate manifolds with shut-off valves.

CFP80 design: filtration area 80 m², capacity 1–2 t/h, weight 5082 kg, chamber volume 1210 l.

By filtration area it sits between CFP50 (50 m²) and CFP100 (100 m²): 80 m². Capacity 1–2 t/h — the same as on CFP50. Chamber volume 1210 l against 1475 l on CFP100. Weight 5082 kg against 6628 kg on CFP100.

One step down by filtration area — CFP50: dimensions 4110×1400×1230 mm instead of 5120×1500×1400 mm. One step up — CFP100: dimensions 5020×1800×1600 mm instead of 5120×1500×1400 mm.
