Dewatering-Bag Geotextile Tubes

Dewatering-Bag

Sediment Bags, Sludge & Breakwater Tubes

Granite offers two options for dewatering operations; Dewatering-Bag for sediment and Geotextile Sludge and Sediment Filter Tubes for dredging spoils, lagoon sludge and slurry which are an economical effective way to keep within NPDES phase II and Clean Water Act compliance and avoid shut downs and/or fines for not removing material like sediment and organics from pumped water and possibly exceeding TSS permit levels. These are ideal for aquaculture use, composting or site remediation.

Our Sediment filter bags are ideal for pumping sediment laden water into where it is filtered and the water passes through the nonwoven geotextile, which retains the sediment and oil too!.

Another novel use for these geotextile tubes has been developed recently for use along storm prone coastlines where the tubes have been installed for shoreline stabilization and as breakwater tubes to protect real estate and natural resources.

Our sediment dewatering and filter bag is fabricated using heavy duty needle punched filter fabric (nonwoven 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. Other options are woven Monofilament (polypro or PE), which are ideal for high flow, rugged, high tensile applications.

These small dewatering filter bag's are effective alternatives to settling ponds/basins and way better than any straw bale structure or inlet filter!!
