Geotextile Dewatering Tubes

Geotextile Dewatering Tubes Environmental Dewatering

1st, a large reduction in volume of the slurry material is achieved as water is removed from the waste.

2nd, the contaminated sediment is changed from liquid to solid that can be earily handled and disposed of in waste storage facilities.

Geotextile Dewatering Tubes
Filling

Sludge is pumped into geotextile dewatering tubes. In most cases, coagulant and flocculant are added to the sludge, which makes the collapse of sludge structure also traps heavy metals and organic contaminants, produces relatively large amounts of free water. Our unique geotextile fabric that capture bonded particles.

geotube dewatering
Dewatering

The effluent drains from geotextile tube through the small pores in our specially woven geotextile. This results in effective dewatering and dramatically volume reduction of the sludge. The volume reduction allows for repeated filling of the geo tube. Clear effluent can be collected and recirculated through flow system.

geotube consolidation
Consolidation

After dewatering, the solids remain in the geobag and continue to densify due to eliminate remianing free water and solids pore water vapor escapes through the geotextile fabric. When full, the geo tube can be deposited at a landfill, remain on site, or the solids can be removed and land applied when appropriate.

Geotextile Dewatering Tubes Marine Structural

Geotextile dewatering tubes works in marine structural similar as works in environmental dewatering. The only difference is marine structure geotextile tube always filling with sand or sand like slurry, it is no need chemical treatment and no consolidation stage or consolidation stage is very fast.

INSTALLATION OF GEOTEXTILE TUBES USED FOR COASTAL STRUCTURES

Experience Level-Geotextile tubes dewatering or geosynthetic tubes shall be installed by contractors having demonstrated successful experience in fillinglarge geotextile tubes of at least 300 m in length.
Plan of Construction - The contractor shall submit a Plan of Construction describing the sequence of operations for the construction of the sand-filled geotextile tubes. The plan shaladdress site preparation, deployment and filling of Tubes. Equipment to be used for geobag sludge dewatering construction shall be specified.
PRE CONSTRUCTION
Tube Foundation - The foundation for the placement of the geotextile tube shall be smooth and free of protrusions which could damage the geotextile. Remnant timber piles, piers, footings,under ground utilities, at or below grade, shall be removed if located within work site. Weak foundation material shall be removed or stabilized.
2.PRECEDURE
Fill Material -Material for filling the geotextile tube erosion control for coastal applications will normally consist of fine sand dredged from adesignated borrow site. Suitable material for filling the tubes will contain not more than 15 percent fines to minimize subsidence of thetubes after filling. lf excessive fines are observed during the filling process, the contractor should divert the flow until more suitable borrow material can be located. If primarily organic and/or fine-grained material, repeated fillings may be required.
1.PRECEDURE
Tube Alignment - Geotextile tubes used in coastal applications normally require alignment within 600 mm of the baseline. The alignment canbe facilitated by a number of methods, e.g., earthen cradles, tiedown straps, or physical buttressing. The filled tubes shall have aneffective height within 150 mm of the specified elevation.
