Dewatering Filter Bags


Solutions for Sediment and Silt Filtration

dewatering filter bagsQuestion: I am looking for dewatering filter bags that I can use around my construction site to filter out silt and sediment materials. Would it be possible to place these bags in a 20 yard dumpster? What sizes are available?

Answer: For filtration of sediment, silt and other materials, the most commonly used product is our Dewatering Filter Bags. Our bags are constructed with an outer nonwoven filter fabric that allows water to slowly drain out of the bag while sediment, silt and other materials are retained inside the bag.

Dewatering Bag Construction and Filtration

silt filtration bagThe construction of a dewatering bag includes the use of either an 8 oz. or 10 oz. nonwoven geotextile filter fabric. These fabrics are designed to filter out materials at various filtration levels depending on the strength of fabric. The 8 oz. material will typically offer a starting filtration level of 80 gpm, while the 10 oz. material can filter at a rate of 60 gpm. Standard sizing includes the following:

  • 6' x 6': 1.44 cubic yds./bag
  • 15' x 10': 6 cubic yds./bag
  • 15' x 15': 9.6 cubic yds./bag
  • 15' x 20': 12 cubic yds./bag
  • 15' x 25': 15 cubic yds./bag

Custom sizing for the dewatering bags is also available, so please do not hesitate to ask.

Dewatering Filter Bag Placement

Placement of the bags on items such as hay bales or other aggregates can help to increase efficiency and filtration levels on your site. To provide the highest level of filtration, bags should always be placed on a flat and level area. Dewatering filter bags can be used in several different locations including the following:

  • Dump Trucks
  • Construction Sites
  • Drop Boxes
  • Trailers and Dumpsters
  • Flat Areas
  • Pond Banks
  • Hay Bales

As seen in the list above, dewatering filter bags can be easily used in dump trucks, drop boxes and other locations where filled bags can be easily transported. To learn how to connect a dewatering bag to a hose, read about Dewatering Bag Connections.
