Sludge dewatering with geotextile tubes

Geotextile container with which a wide variety of sludge types can be dewatered

Large quantities of sludge are produced, especially in industry and mining. In addition, dredged material accumulates during watercourse maintenance or maintenance measures to ensure safe shipping traffic. The environmentally friendly disposal of these sludges often poses a challenge and is associated with great effort and costs. The dewatering of the various sludges before removal has therefore established itself as both economically and ecologically viable and can be carried out using different dewatering methods. The SoilTain® dewatering tube is a geotextile container that can be used to drain a wide variety of slurries or wet-dredged materials. The gravimetric dewatering of the sludge is accompanied by a reduction in volume. The geotextile dewatering tube system is more efficient than a classic flushing field and more cost-effective than mechanical dewatering methods such as belt or chamber filter presses.

Sludge dewatering: A variety of sludges

Sediments / Dredged material
  • Made from mineral & organic material
  • Often contaminated with TBT, PCB or heavy metals
Dredged material as an example of sludge to be dewatered
Sewage sludge
  • Product of biological waste water treatment processes
  • Often no mechanical dewatering for small wastewater treatment plants
Sewage sludge as an example of sludge to be dewatered
Mining residuals
  • Constituents, may pose an environmental hazard
Coal sludge as an example of sludge to be dewatered
Industrial sludge
  • Organic & Mineral Slurries
  • Can be better stored in demobilised form

Infrastructural sludges
  • Often occurs on construction sites
  • There is often little space available for storage

Easy installation & application

Dewatering with SoilTain
Step 1

Extraction

Sludge or dredged material can be removed with a suction dredger, for example.

Step 2

Conditioning

A flocculant is added to the sludge. This causes the particles suspended in water to agglomerate into larger flakes.

Step 3

Dewatering

The geotextile container dewaters the sludge in a static gravimetric process. The solids are retained by the specific opening width of the filter fabric.

Step 4

Disposal

Compaction reduces the water content in the tubes until the dewatered sludge can be landfilled or recycled.
