CFP50 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.

CFP50 design: filtration area 50 m², capacity 1–1.5 t/h, weight 3456 kg, chamber volume 748 l.

The smallest unit in the line by filtration area: 50 m² against 80 m² on CFP80. Capacity 1–1.5 t/h — the same as on CFP80. Chamber volume 748 l against 1210 l on CFP80. Weight 3456 kg against 5082 kg on CFP80.

One step up by filtration area — CFP80: dimensions 5120×1500×1400 mm instead of 4110×1400×1230 mm.
