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
Construction Sludge Dewatering
Excavation, diaphragm wall and wash-water sludge, reduced to a transportable cake.
Construction sludge is a mixture of everything the site produces. Volume reduction on site decides how often the tankers have to come.
- Typical capacity
- 10 – 60 m³/h
- Slurry type
- Construction sludge
- Target cake
- 25 – 40 % dry solids
What the plant has to do
Sludge arrives from the excavation, the diaphragm wall and the wash bay, so the plant is buffered against the swings between activities. The cake leaves the site and the filtrate returns to the site water system.
Recommended treatment process
Each stage is selected around the slurry and the disposal route.
- 01
Receiving
Sludge is received in a tank and mixed to a workable consistency.
- 02
Screening
Coarse material and debris are taken out first.
- 03
Conditioning
Dosing is set so the fines will release water in the press.
- 04
Dewatering
The press reduces the volume that has to leave the site.
- 05
Cake and water
Cake goes to disposal; filtrate returns to the site water system.
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
Disposal route
The target cake moisture follows the tipping or recycling route the site uses.
Variable feed
A buffer tank and load-following dosing absorb the swings between activities.
Site water
Filtrate quality decides whether it can be reused on site or has to be tankered.
Frequently asked questions
Typically 60 – 80 % of the volume leaves as clear water, so the tanker count drops by roughly the same proportion.
Yes — wash water is usually mixed with the sludge and treated in the same cycle.
