Dewatering tubes, also known as geobags or geotubes, act like a filter container, trapping solids inside while allowing water to escape.
Easy to operate
SLUDGE
Geotubes can dewater almost any sludge type - from sewage to mine tailings, plastics, to silt. Simply choose the geotextile suited to your wastewater type and see how reducing the water content of your sludge lowers handling, treatment and removal costs.
SIMPLE
Sludge dewatering bags are filled by pumping or gravity drainage. As they inflate, water filters out through the geotextile for collection or disposal. Small projects use our hanging bags with forklift handles for mobility. Larger projects use tubes that lie flat along the ground, or on a HDPE liner.
SMART
Geobags provide a low-cost, low-maintenance alternative to mechanical dewatering equipment. Let gravity and pressure do the work for you, so you can focus on other tasks.

Effective dewatering
Geobag dewatering typically reduces moisture content of solids by 50-70%, minimising the waste volume and associated costs. We offer a range of geotextiles with different aperture sizes: one for organic or flocculated sludge, one for inorganic sludge like coal or mineral tailings, and a third for ultrafine particle dewatering.
Expertly made
Our woven geotextile material is durable and resistant to chemicals, ensuring reliable performance in remote wastewater treatment sites and alongside operational facilities. With a variety of sizes available, operators can easily adjust dewatering capacity as needed.
