High strength PP woven Marine sludge dewatering bag for seawall protection
Description:
PP woven marine sludge dewatering bag or a large tube bag and inclusion made of high-strength geotextiles, the diameter of which can be changed as needed, up to several tens of meters long. Dewatering Bag were originally used in the dike project. At present, through the efforts of the vast number of technical workers, they have been applied to environmental protection, agriculture and other fields. With the deepening of people's research, their application fields will become more and more extensive.
Main Feature:
PP woven marine sludge dewatering bag used for landfill
1.High strength, low deformation geobag
2.Durability: steady property, not easy to resolved, air slaked and can keep the original property long term
3.Anti-erosion: anti-acid, anti-alkali, resists insects
4.Permeability: could control the sieve size to retain certain permeability tube
5.Effective high volume containment
6.Efficient dewatering and volume reduction
7.Cost effective
8.No special equipment required

Application
The whole process has three-steps:
Step 1: Filling -- Sludge (dredged material) is pumped into the tube container. Environmentally-safe polymers are added to the sludge, which makes the solids bind together and water separate. The TenCate tube?container's unique fabric confines the fine grains of the material.
Step 2: Dewatering -- Clear effluent water simply drains from the tube 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 tube 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 tube container and contents can be deposited at a landfill, remain on-site, or the solids can be removed and land-applied when appropriate.
