Hydraulic Structure & Environmental Dewatering

Applications

Geotextile Tube(Geobag) used as Environmental Dewatering

Geotextile tube dewatering filling with Environmental Sediments, Industrial Sludge, Sewage, Mining Residuals and etc. There are too many sediments carried by rivers and streams into down gradient harbors, estuaries and deltas every year in the world. The dredging, a safe and efficient strategies is necessary, the geotextile dewatering tube not only to dewater the dredged material while under pressure but also to decontaminate them is the unltimate goal. By dewatering we mean to decrease the water content of slurried material to a point where geotextile bags handling of the sediments by standard earth moving equipment is possible.

Geotextile tubes are a reliable, versatile, and eco friendly solution for dewatering. They offer many benefits over traditional methods and can help to effectively manage and remove excess water from construction and excavation sites. If you are looking for an effective solution for dewatering, consider using geotextile tubes as an alternative.

Municipal Waste

The dewatering of municipal waste sludge was a early and mature application for geotextile tube. Most municipal sewage treatment plants store the generated sludge in ponds. 

Geotextile tubes are used extensively for dewatering sludge from these containment ponds. The effluent water is normally back to the ponds, and solids disposed of elsewhere.

For the limited space available, many customers use small size geobag, which can put into ‘rectangle steel box’ and can be easy moved by truck. It is also called MDS dewatering system.

mine dewatering
Mining Waste

The mining of minerals will produce various types of waste. Such as tailings, mineral fines and processing sludge.

Large mining activities produce big amounts of tailings, which are stored in open tailings dams in isolated locations. However, small mines produce small tailings, which are close to population or environmentally sensitive areas.

The management of these tailings or their remediation are necessary, because in many cases the tailings have to be dewatered first before they can be rendered stable and inert.

geobag dewatering
Contaminated Sediments

The contaminated sediments are always come from industrial effluent waste that settle into rivers, lakes, ponds and streams within timeby. They are such as: PCBs, PCPs, PAHs, lead, copper, zinc, arsenic and etc. These contaminants are harmful to humans, animals and aquatic lifes. Environmental dredging is the most common method of contaminated sediment remediation. The sediment is dredged and pumped into geo tube and transported after weeks or months consolidation.

geotextile tube dewatering
Agricultural Animal Waste

Chicken, Cattle and Pig farms produce large amount of waste, which is commonly stored in retention ponds. Over time there ponds are filled with sludge, and they have to be cleaned out periodically.

Animal waste is more fine than sewage waste, it normally has to be treated with coagulate and flocculate to ensure colloids and nutrients are contained within the geotextile tube during dewatering.

geotube dewatering
Industrial Waste

Many industrial processes produce waste which is stored in waste ponds on the industrial site. Over time these ponds fill with waste sludge, and have to be cleaned to continue function.

A common method of these waste reclamation is to dewater the waste sludge from ponds and dispose of it in landfill or use it for other applications.

geotube dewatering
Food Processing

Food processing produces large quantities of slurry waste, which comes from manufacturing process such as Potato Processing(washing and skin waste), Cheese Processing, Wine Processing and etc.

Slurry waste stored in sedimentation pond and need to be dewatered periodically.

Applications

Geotextile Tube(Geobag) used as Hydraulic Structure

Geotextile tubes, also known as geobags or geocontainers, are an innovative solution for building structures in various applications, from coastal protection to erosion control. Made of high strength, woven polypropylene geotextile material, geotextile tubes are designed to withstand the forces of water, waves, and erosion, making them an ideal choice for challenging environments. 

geotube seawall
Revetments

Geotextile tubes(geobag) often filled with sand slurry for used as revetment structures. They are used for both submerged and exposed revetments. For submerged revetments the geotextile tube is always covered by local soil. For exposed revetments, the geotextile tube is exposed throughout it’s design life.

To prevent erosion of the foundation, the geotextile tube is always to install a scour apron, which is anchored by a small geotextile tube, we call it ‘anchor tube’. Revetments are also constructed using multiple geo tube layers. Here the geobags are stacked over to reach the required design heights. A common method of these waste reclamation is to dewater the waste sludge from ponds and dispose of it in landfill or use it for other applications.

geotube dyke
Protection Dykes

Geotextile tubes(geobag dewatering) are used for protection dykes, where they prevent flood and storm damage to valuable structures. They can also used for river, lake works.

 

When geotextile tube protection dykes are constructed, always it is covered by local soil. Thereby ensuring no damage caused by activities and long term sunlight exposure.

Once geotextile tubes are used for river or lake works, it is always leave the geobag exposed except for major structures, where rock armour layers may be placed over it to dissipate hydraulic forces. 

Slurry waste stored in sedimentation pond and need to be dewatered periodically.

geotube breakwater
Offshore Breakwaters

Geotextile tubes(geobags) are used for offshore breakwaters to prevent the erosion behind shoreline developments. The geotextile tube is located at a certain distance from offshore in order to weak or eliminate wave energy before they can reach the shoreline. 

geotube groynes
Geobag Groynes

Geotextile tube(geobags) as groynes, which to prevent shoreline movement of sediment. In most cases the geotextile tubes are left exposed, but coatings or a rock covering or concret matress may be applied, dependiing on the situation and required life span.
