Chamber Filter Press
Plate-and-frame dewatering for construction and industrial slurry.
- Filtration area
- 10 – 250 m²
- Filtration pressure
- 0.6 – 1.6 MPa
- Capacity range
- 5 – 120 m³/h slurry feed
TBM Slurry Treatment
High-capacity slurry treatment for slurry shield tunneling, sized around the drive and the geology.
A slurry TBM sets the flow; the separation plant has to follow it through changing geology without stopping the drive.
- Typical capacity
- 150 – 400 m³/h
- Slurry type
- Bentonite / mixed face
- Target cake
- 30 – 45 % dry solids
What the plant has to do
The separation plant is laid out along the drive so it can be extended as the machine advances. Coarse material is stockpiled, the sand goes to its own skip and the cake leaves the site by truck.
Recommended treatment process
Each stage is selected around the slurry and the disposal route.
- 01
Coarse separation
A large screen takes out cobbles and cutter debris before the cyclones.
- 02
Desanding
Two-stage cyclones cut the sand and silt fractions to protect the press.
- 03
Conditioning
Flocculant dosing is automated from the measured solids load.
- 04
Dewatering
Membrane presses give the dry solids the disposal route requires.
- 05
Water recovery
Filtrate is returned to the TBM feed tank, closing the loop.
Recommended equipment
Equipment is configured around the capacity, solids concentration and target cake moisture of your project.
Membrane Filter Press
Squeeze dewatering for higher dry solids and shorter cycles.
- Filtration area
- 10 – 200 m²
- Filtration pressure
- 0.6 – 1.6 MPa
- Capacity range
- 5 – 100 m³/h slurry feed
Automatic Filter Press
Automated filtration cycles for continuous industrial operation.
- Filtration area
- 10 – 200 m²
- Filtration pressure
- 0.6 – 1.6 MPa
- Capacity range
- 5 – 100 m³/h slurry feed
Operating considerations
Changing geology
The plant is designed for the hardest ground in the drive, not the average.
Redundancy
Feed pumps and dosing run duty/standby so the drive does not stop for maintenance.
Layout along the drive
Equipment is arranged so the plant can be extended as the drive advances.
Frequently asked questions
From the TBM slurry flow and the maximum solids load, not from the tunnel diameter alone.
Yes — the separation stages are set for the finest and the coarsest material in the drive.
