Dewatering Bags to Remove Copper

Sludge Dewatering Project for Heavy Metal Removal

dewatering bags to remove copperDewatering Problem: A visitor asked about dewatering bags to remove copper and spoke about his sludge issue. The sludge has a copper content above acceptable levels for composting.

He is looking for a sludge dewatering solution that would lower the concentrations in the organic particles and make it easier to remove copper from the water itself. The goal is to remove the water with the dissolved copper in it rather than having the copper precipitated out into the organics in a drying process.

Dewatering Solutions

Standard dewatering bags use a nonwoven geotextile material, while dewatering tubes use a woven geotextile. Our product specialists worked with the manufacturing locations to offer the correct fabric material and bag filter for sludge dewatering. Now, he can remove the copper and water together. GEI Works provided the solution he needed, helping to solve his sludge dewatering problem.

Dewatering Bags
The Dewatering Bag is a filtering device typically designed to remove silt, sediment, and other small materials from water. These bags are typically made from a nonwoven 8 or 10 ounce geotextile, although they have also been made from 6 ounce, depending on the requirements.

The nonwoven geotextile fabric uses a needle-punched filtering design. The holes are small enough to prevent particles from leaving the bag, while remaining large enough for water (and occasionally water and copper) to leave the bag. Standard dewatering bag sizes range from 6' x 6' to 15' x 25'.

Dewatering Tubes
dewatering sludge tubesA common choice for sludge dewatering is the Dewatering Tube. The tubes are constructed of a woven geotextile material for high levels of filtering and sludge removal.

The sludge tubes are significantly larger in size, ranging in length from 50 to 250 feet. They are frequently used for applications requiring large amounts of water, including lakes, waste water treatment plants, and lagoons.

Dewatering Considerations
There are a number of factors to consider when choosing sludge removal equipment. Sludge tubes and dewatering bags are used for similar applications, but sometimes one in a better option over the other. Dewatering considerations include:

  • Slurry / Sediment Concentration
  • Amount of Liquid in Need of Dewatering
  • Clear Drainage Areas
  • Footprint Space
  • Safe Location Away from Hazards
