What is in a geotube?
The Geotubes are also known as geobags — used for sludge dewatering projects of different sizes because of their simplicity and low-cost factor. They are containers that are hydraulically filled with a slurry mix of sand and water.
How much do geotubes cost?
Materials for a seawall can be between $1,200 to $3,000 a foot, but for the geotubes a person can expect somewhere between $200 to $250 a foot.
Can geotubes be reused?
The specially engineered TenCate Geotube® textile retains the solids while releasing the clear water through the pores of the fabric. The effluent is typically of a quality that can be reused for mine processing operations, making this an economical and sustainable technology for mine water management.
How do I fill in geotube?
How it works
- Step 1: Filling. Sludge (slurry material) is pumped into the TenCate Geotube® container.
- Step 2: Dewatering. Clear effluent water simply drains from the TenCate Geotube® container through the small pores in the specially engineered textile.
- Step 3: Consolidation.
How do geotubes dewater sludge?
How TenCate Geotube® Dewatering Technology Works? 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.
What is geotube seawall?
A geotube, which are made of stacks of natural or synthetic fibre, is filled with sand to form a seawall. At present, workers are preparing the ground to lay the geotubes. However, they are met with another hurdle – the unavailability of sand to fill geotubes.
How does a geotube work?
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.
What is the purpose of geotube?
Geotube® systems are used for shoreline erosion protection, land reclamation, island creation, wetlands creation, construction platforms, revetments, dykes, groynes and offshore structures.
