Millions of gallons of sludge have been pumped into TenCate Geotube® containers for containment and dewatering of industrial waste, municipal sludge, and hazardous contaminated sediments. Paper mills, chemical companies, industrial plants, and nuclear power plants are just a few of the clients that have benefited from TenCate Geotube® dewatering technology.
TenCate Geotube® dewatering technology is the low cost, high volume dewatering solution. The dewatering process is simple and effective.
Key Benefits of TenCate Geotube® Dewatering Technology
- Effective high volume containment
- Efficient dewatering and volume reduction
- Cost effective
- No special equipment required
How It Works
TenCate Geotube® dewatering technology is the low cost, high volume dewatering solution. The dewatering process is simple and effective. The pumping process is repeated until the tube is full. Eventually, the solids can be handled as dry material, increasing options for transportation and disposal.
How TenCate Geotube® Dewatering Technology Works
Step 1: Filling – Sludge (dredged 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. And this volume reduction allows for the 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.
