FabriFlex DT dewatering tubes are engineered tubes specially designed for large scale industrial dewatering of municipal wastewater, industrial pond dredging, agricultural waste dredging, etc. They can be customized with different materials and sizes, depending on the application’s requirements.
The filter textile used for dewatering allows dissipation of water through its opening while retaining sediment and sludge within the tube. Upon completion of dewatering process, filter cake inside the tube can be easily removed from site, providing an environmentally friendly solution for the project.
FabriFlex DT dewatering tube undergone extensive quality control. Ensuring the quality of each component.
High Filling Capacity
FabriFlex DT are manufactured with engineered design material and fabricated with high seam strength hence can provide a higher sludge fill volume compared to others.
High Flexibility
FabriFlex DT dewatering tubes are highly flexible, able to conform to deformation without jeopardizing the system.
Fast Installation
Filling of dewatering tubes is achieved by in-situ material, accelerating the desludging process.
Highly Versatile
FabriFlex DT is highly customisable to suit the site condition. It’s versatile arrangement ensures different configuration possibilities.
Cost Effectiveness
FabriFlex DT are used to improve the effectiveness of sludge management. Dewatered waste can significantly reduce the total volume sent to landfill for disposal.

A dewatering tube is a large geotextile container designed to separate water from sludge, slurry or sediment.
During operation, the slurry is pumped into the tube. The engineered geotextile allows excess water to drain through its openings while solid particles remain contained inside.
As water continues to drain, the retained material consolidates and its overall volume is reduced.
This makes dewatering tubes suitable for projects involving large quantities of wet sludge where conventional mechanical dewatering may be impractical or require additional equipment.
Dewatering Tube Applications
FabriFlex DT Dewatering Tubes can be used across industrial and environmental applications involving sludge or sediment management.
Municipal Wastewater
Wastewater treatment processes can produce sludge containing significant amounts of water.
A dewatering tube can retain the solids while allowing excess water to drain, reducing the volume of material that requires subsequent handling.
Industrial Pond Dredging
Sediment accumulated in industrial ponds may need to be dredged as part of maintenance or rehabilitation works.
Dewatering tubes provide containment for dredged slurry while separating water from the retained sediment.
Agricultural Waste
Agricultural operations can generate slurry and wastewater containing suspended organic material.
Geotextile dewatering can assist in separating solids from liquid for more manageable treatment and disposal.
Mining and Slurry Management
Dewatering tubes may also be used for applications involving mining slurry, tailings and sediment where large-volume containment and water removal are required. Geotextile tubes are widely used for dewatering slurried materials in mining and industrial environments.
Dredged Sediment
River, drain, pond or reservoir dredging can generate large quantities of water-saturated sediment.
A dewatering tube allows the dredged material to be contained while water drains through the geotextile.
Dewatering Tube vs Dewatering Bag
Both solutions use geotextile filtration to separate water from solids, but they generally serve different project scales.
Factor
Dewatering Tube
Dewatering Bag
Typical capacity
Large-volume applications
Smaller-volume applications
Main use
Large sludge or dredging projects
Localised or smaller dewatering works
Installation
Requires suitable site preparation and pumping setup
Generally easier to deploy
Handling
Designed to remain in place during filling and consolidation
More suitable where smaller containers are preferred
Applications
Wastewater, dredging, mining and agricultural sludge
Smaller industrial or construction dewatering
FabriFlex also manufactures dewatering bags for industrial sludge and dredging applications.
Differences Between Dewatering Tubes and Geotextile Tubes
While both dewatering tubes and geotextile tubes use geotextile fabric to separate solids from slurry or wastewater, they differ significantly in design, application, and handling requirements.
1. Size and Shape
Dewatering tubes (often referred to as dewatering bags) are smaller and more compact, typically resembling large sandbags. They are ideal for small-scale or temporary projects and can be used in confined or hard-to-access areas.
Geotextile tubes, on the other hand, are much larger and take on a long, cylindrical (sausage-like) form. These are engineered for large-scale dewatering operations and are capable of managing high volumes of sludge or sediment.
2. Application Scope
These tubes are suited for localized projects such as residential construction, utility work, or sediment control in tight areas. Their size and simplicity make them quick to deploy and easy to manage.
Geotextile tubes are designed for industrial or environmental projects—such as coastal restoration, municipal sludge dewatering, or mining—where durability and high-volume capacity are essential.
3. Filling and Setup
Dewatering tubes typically have wide openings, making them easier to fill manually or with smaller equipment. This makes them more practical for sites with space constraints.
Geotextile tubes may require pumps and specialized handling equipment due to their larger scale. They often need to be anchored and monitored over a longer period to ensure effective dewatering and containment.
