Bag Filters for Sludge Dewatering
Copper Removal Dewatering Bags
A bag filter for sludge dewatering can help remove copper from sludge. One of our customers asked about dewatering bags to remove copper and spoke about their sludge issue. The sludge has a copper content above acceptable levels for composting.
The customer was looking for a bag filter for sludge dewatering that would lower the concentrations in the organic particles and make it easier to remove copper from the water itself. The goal was to remove the water with the dissolved copper in it rather than having the copper precipitated out into the organics in a drying process.
Nonwoven Bag Filter for Sludge Dewatering
Standard sludge 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, the customer can remove the copper and water together. We were able to provide the solution the customer needed, helping to solve their sludge dewatering problem.
Sludge Dewatering BagsThe Dewatering Bags and Silt Filtration Products are filtering devices 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 sludge dewatering bag sizes range from 6' x 6' to 15' x 25'.
Dewatering Geotextile Tubes
A common choice for sludge dewatering is the Geotextile Dewatering Tube. The tubes are constructed of a woven geotextile material for high levels of filtering and sludge removal.
A bag filter for sludge dewatering is 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, wastewater treatment plants, and lagoons.
Bag Filter for Sludge Dewatering ConsiderationsThere 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 is a better option over the other. Dewatering considerations include:
- Slurry and Sediment Concentration
- Amount of Liquid in Need of Dewatering
- Clear Drainage Areas
- Footprint Space
- Safe Location Away from Hazards
