TenCate Geotube® dewatering containers are an effective dewatering technology fabricated from a specially engineered textile that provides confinement of the fine solids inside the container, while allowing water to permeate through the engineered textile. As the water drains, the solids continue to densify and consolidate over time. Once the solids are fully consolidated or have met minimum requirements for transport, several options are available for disposal of the dewatered material.
The containers are custom sized to save land space and are ideal for areas where space is a constraint. Geotube® dewatering containers are designed to optimize the solids retention and effluent discharge rate and quality making it a highly efficient and environmental friendly solution for various sludge dewatering applications.
Advantages and Applications of TenCate Geotube® Dewatering technology
How TenCate Geotube® Dewatering Technology Works?
Step 1: Filling
Sludge (slurry material) is pumped into the TenCate Geotube® container. Environmentally-safe polymers are added to the sludge, which makes the solids bind together and water separate. The TenCate Geotube® container’s unique fabric confines the fine grains of the material.
Step 2: Dewatering
Clear effluent water simply drains from the TenCate Geotube® container through the small pores in the specially engineered textile. This results in effective dewatering and efficient volume reduction of the contained materials. The volume reduction allows for repeated filling of the TenCate Geotube® container. Over 99% of solids are captured, and clear filtrate can be collected and recirculated through the system. The decanted water is often of a quality that can be reused/returned for processing or returned to native waterways without additional treatment.
Step 3: Consolidation
After the final cycle of filling and dewatering, the solids remain in the bag and continue to densify due to desiccation as residual water vapor escapes through the fabric. Volume reduction can be as high as 90 percent. When full, the TenCate Geotube® container and contents can be deposited at a landfill, remain on-site, or the solids can be removed and land-applied when appropriate.
Geotube® dewatering containers are prefabricated using high strength and quality seaming techniques into tubular, bag-like, or other forms with filling ports or other provisions for site filling.
