Silt Filter Bags
Specifications for a 6' x 6' Dewatering Bag
Question: I would like information about silt filter bags. Do you have specifications for a 6' x 6' dewatering bag model available? Can you provide them?
Answer: Thank you for contacting GEI Works! Our Taurus Dewatering Bags, also known as silt filter bags, are ideal for filtering sediment laden water. The water passes through the nonwoven geotextile fabric while retaining the sediment inside the bag.
6' x 6' Dewatering Bag Specifications
- Material Options: 8 oz. Nonwoven, 10 oz. Nonwoven
- Discharge Hoses: Up to 4"
- Capacity: 1.44 cubic yards per bag
All silt filter bags are fabricated using heavy duty needle punched filter fabric (non woven geotextile) which provides high permittivity (water flow) and a fine pore structure that allows water to flow through freely, while preventing fine soils from piping through. Another material option is woven monofilament (polypro or PE), which is ideal for high flow, rugged, and high tensile applications.
In addition to this bag, we also offer several other standard sizes as well as custom sizes:
- 15 ft x 10 ft
- 15 ft x 15 ft
- 15 ft x 20 ft
- 15 ft x 25 ft
Dewatering filter bags may be placed directly on the ground, in porous surfaces, and in various other containers (even dump trucks!) to help filter, transport, and store materials.
Additional Dewatering Products
Sometimes silt filter bags are too small for a project or too broad to fit in a pipe space. Luckily, GEI Works provides two other dewatering filtration solutions for these instances.
- Dewatering Tubes - Geotextile tubes are larger, stronger version of the silt filter bags. They use a stronger woven material, and sizing begins with a 50-foot length. Dewatering tubes are generally used for lagoon dredging, beach breakwaters, and other large scale project.
- Dewatering Socks - Our filtration socks are designed as long, narrow silt filter bags. They attach to one end of a pipe or hose, allowing the water flow to filter through the sock. Standard sizes have a 4" to 16" diameter and are 5 feet long. As with many of our products, custom sizing is also available.
