Dewatering Bags for Coal Slurry
Sludge Tubes for Coal Dewatering
Question: I work at a coal processing plant. I am looking for specs, price, and availability on dewatering bags for coal slurry. I need it to have a lay flat size of 100' x 20'.
Answer: We offer two dewatering product options for dewatering operations:
- Dewatering Bags for sediment, silt, and other small dewatering jobs
- Geotextile Tubes for dredging spoils, lagoon sludge and slurry, and other larger locations
There are a couple of differences between these two dewatering products. Dewatering bags for coal slurry are designed in smaller sizes and made from a nonwoven geotextile filter material. The bags are commonly used on project sites for dewatering small ponds, construction site runoff, and other smaller jobs.
Geotextile tubes, also known as sludge tubes or geotubes, are significantly larger in size and made from a woven geotextile material. These dewatering products are used for large jobs such as the dewatering of large lagoons, WTTP sludge removal, and other larger locations.
Choosing the Right Dewatering Products
Due to the size of the dewatering bags for coal slurry needed, the best option for your location would probably be the large sludge tubes. When sludge dewatering bags are compared to geotubes, the tubes are significantly larger and can be used for large coal dewatering projects and jobs.
Geotextile tubes are filled to 85 percent capacity with coal slurry and left on site to consolidate. Once consolidation process has taken place, the sludge tubes are refilled, and the geotubes sludge dewatering cycle continues. When consolidated solids reach 85 percent of the total capacity, the tubes are ready to be transported away from the area for disposal.
Sizing for the tubes can be anywhere from 50 to 250 feet in length and 15 to 90 feet in circumference. Depending on the amount of materials you need to contain, the available space you have in your location, and the concentration of coal slurry needing to be processed, different dewatering products may work better than others for your project.
