Dewatering Bags and Other Equipment
Dewatering bags, socks, and tubes are designed to provide an economical solution to dewatering and sludge removal processes. Often used on construction sites, lagoons, waste water treatment plants, power plants and dredging locations, dewatering products provide a quick way to remove sediment, sand, sludge, and other dredging materials.
Dewatering Products Variety
Dewatering filter bags, also known as the silt bags or sediment filter bags, are smaller dewatering options made from nonwoven materials. A geotextile bag is available in sizes ranging from 6' x 6' to 15' x 25.'
By contrast, dewatering tubes are built in sizes up to 250' in length and are made from a heavier woven geotextile fabric. Some of the additional differences between these products can be seen below:
Dewatering Silt Bags
- Nonwoven Geotextile Fabric (typically 8 or 10 oz.)
- Available Fitting for a Discharge Port
- Ideal for Construction Site Runoff or Small Dewatering Projects
Dewatering Filter Socks
- Nonwoven Geotextile Fabric
- Fits on the Ends of Pipes and Hoses
- Smaller and narrower Size
- Woven Geotextile Fabric
- Larger in Size
- Lengths Up to 250 feet
- Circumferences Up to 90 feet
- Multiple Filling Ports
- Ideal for Lagoon Dewatering, Sludge Removal, or Breakwater Applications
Dewatering products have also been used by companies as a way to successfully stay in compliance with clean water regulations such as NPDES Phase II and the Clean Water Act. A dewatering bag is an excellent way to filter out sediment and allow a clean water flow from your site.
Dewatering Products Placement
Placement of dewatering bags or tubes varies based on application, available space, and specifications on your site. In general, these materials have been placed in some of the following locations:
- On the Ground - This is a great option for either the dewatering sludge bag or the dewatering tube. Runoff from bags should be directed to the nearest inlet, while runoff from tubes (often larger) can be directed to retention ponds.
- Along Shores - Dewatering tubes are often placed along shorelines to act as a breakwater structure and protect against erosion.
- Drop Boxes or Dump Trucks - Smaller dewatering products can be placed in these containers for dewatering, transportation and disposal.
