Sludge Dewatering Tubes
Bag Filter for Sludge Dewatering at a Paper Mill
Question: I am interested in sludge dewatering tubes. I am evaluating dewatering methods involved in drying sludge from a paper mill. We have done studies and the sludge is not considered hazardous. It has characteristics similar to silt and fine sand. We are in need of information for these geotubes including the type of material used, whether it is woven or non-woven, etc. We were also wondering if you offer the hanging dewatering bags.
Answer: The Sludge Tube is a great choice for dewatering methods at paper mills, agricultural facilities, and waste water treatment plants. Due to their frequent use in outdoor locations, these geotubes are typically made from a woven geotextile material that has been UV stabilized for extended outdoor use.
Sludge Tube Specifications
Sludge dewatering tubes have several different specifications that help equip the unit for use in WWT plants, mills, and lagoons. Standard specifications include:
- Standard Lengths: 50 to 250 feet
- Circumferences: 15, 22.5, 30, 45, 60, 75, or 90 feet
- Filling Ports: Number dependent on the length and volume of your sludge tube with 1 - 5 ports spaced evenly along the tube (every 50 feet).
- Material: Woven Geotextile Fabric

Hanging Dewatering Bags
The hanging sludge dewatering bags are typically used to help customers test their dewatering methods and help determine the fabric and pore size required for your specific conditions. These bags are available upon request for an accurate assessment of your area. Contact GEI Works for more information.
Sludge Tube Fill Capacity
Sludge dewatering tubes are typically filled with your slurry mixture until the bag reaches approximately 85 percent of its fill capacity. After this point has been reached, sludge dewatering tubes are given time to consolidate. Once settled, the tubes are filled again. This process continues until the sludge dewatering tubes are filled to 85 percent of their total capacity.
After the geotextile tubes have reached 85 percent of their filled capacity, they can then be placed inside a dump truck or other transportation vehicle and moved to a disposal location. Dewatered sediment can be used as fill, compost, or various other beneficial uses, depending on the final material composition.
