Geotextile Sediment Tubes
Hello. I am looking at the geotextile sediment tubes. I am wondering, how long do these bags usually take to drain or filter. It says that bags take awhile to drain but I do not see any estimate of time.
- Type of Fabric Being Used
- Size of the Bag or Tube
- Type of Sediment or Sludge being Filtered
- Speed at which the Materials are being Pumped into your Bag
The first thing you will want to establish is whether you are looking for a dewatering bag or a dewatering tube. The geotextile filter bag is much smaller in size and is designed for silt or sediment removal on locations like construction site or other operating location.
The dewatering tube, by contrast, is a much larger geotextile product and is commonly used for sludge dewatering, lagoon dewatering or large removal jobs.
Filtering for Dewatering Bags
Dewatering Bags are typically built in a size of either 8 ounces or 10 ounces. The material used will be a non-woven fabric that creates needle-punched pores for small filtering jobs.
- 8 oz. Fabric: 80 gpm per square foot
- 10 oz. Fabric: 60 gpm per square foot
Filtering times will vary depending on the speed of pumps in your location and the amount of sediment needed to be filter out.
Filtering for Dewatering Tubes
Made in larger sizes and capacities, the Dewatering Tube is designed for high strength filtering jobs and uses a woven geotextile fabric. These fabrics may vary in strength depending on their fabric material which can include both polyester and polypropylene.
- Solids Content in your Slurry or Sludge
- Tube Size/Volume/Height
- Location of your Tube
- Rate of Pumping
- Amount of Water Requiring Dewatering
Since these dewatering projects often involve large amounts of water, sludge or sediment, speeds may also be increased through the following methods:
- Polymer: The addition of polymer is often used to increase pumping times. If you are considering this option, it is best to use polymer specialist to treat your materials.
- 24/7 Run Time: Dewatering tubes can be run 24/7, extending the amount of time available for dewatering.
