Information on Geotextile Sludge Tubes
Question regarding info on geotextile tubes to remove silt. I am doing project on geotextile tubes and I need some basic information. Can you help?
Answer:
Greetings! Thank you for contacting Granite Environmental. I'd be happy to tell you about our Geotextile Tubes. They are are ideal for filtering materials on projects and are used extensively in various locations for waste water or sludge dewatering projects. Places and applications where these large dewatering tubes have included:
- Waste Water Treatment Plants (WWTP)
- Agricultural Ponds
- Aquaculture Facilities
- Pulp Mills
- Paper Mills
- Industrial Lagoons
- Large River or Pond Dewatering Projects
- Sludge Dewatering
- Large Sediment Removal Projects.
The technology used for these tubes is often the most inexpensive economical route to consider for treating a specific sludge / slurry stream. Simple soil analysis in conjunction with hanging bag tests can economically determine the correct fabric and pore size necessary for the conditions to safely deploy the Dewatering Tube in an environmentally responsible manner.
Things to Consider:
- Slurry / Sludge solids content
- Placement of inlets for distribution of sludge/solids in each tube
- Drainage of clear, free-flowing filtrate from each tube to retention area or reservoir.
- Tube height should not exceed 5’ and inflation rates of multiple tubes applications
- Stability of additional layers of tubes (if filling a second layer tube)
- Safe location tubes with respect to potential hazards and area.
Additional Info on Geotextile Tubes
The geotextile tube can be made in a wide range of sizes includes site-specific configurations. In general, lengths for these tubes are typically made anywhere from 50 to 200 feet with circumferences anywhere from 15 to 90 feet. Please contact us for additional information regarding the sizing of these bags.
Choosing the correct size depends significantly on your filtering rates, pumping rates and the type/amount of sediment or sludge you need to retain.
These tubes have also been implemented in various breakwater applications (seen in image above). Beaches and coasts work to install these geotextile tubes along the shoreline, allowing sand to be retained while water filters in and out with the tides.
Hope the provided info on geotextile tubes above helped you to better understand what products are required for your project.
