Small-Scale Dewatering Bags

Zebratube®’s small-scale dewatering bags are manufactured from an engineered woven geotextile that enables retention of solids within the bag whilst filtrate percolates through the geotextile.

Our small-scale square bags are perfect for the dewatering and containment of smaller sludge volumes on a continuous basis.

Our square dewatering bags are fitted with forklift handles, enabling easy handling of the dewatered material.

Process Flow
1 Feeding the bags

Slurry is fed to the bag either by pumping the material or via gravity drainage.

2 Addition of flocculant

In some cases the slurry has to be conditioned through the addition of a flocculating agent. Particles agglomerate allowing for retention of fines and increased dewatering efficiency.

3 Settling and Dewatering

Solid particles settle inside the bag allowing the formation of a filter cake on the surface of the geotextile. The filter cake enhances filtration efficiency, allowing clear filtrate to percolate through the geotextile. Filtrate can be captured and re-used.

4 Removal of dry material

Our unique small-scale square bags come with forklift handles, allowing easy removal and transport of the dewatered material within the bag.


Zebratube® geotextile dewatering bags offer the following benefits in comparison with conventional dewatering equipment:

  • Easy handling and disposal of the dewatered material.
  • Cost-effective dewatering on a small scale when compared with mechanical dewatering equipment.
  • The ability to easily scale the dewatering process in line with production requirements.
  • Minimal skilled labour required, with low labour requirements overall.
  • Simple auxiliary equipment required, with minimal maintenance requirements and low energy usage.
  • Filtrate can be captured, allowing for containment, recycling and re-use.

Our small-scale dewatering bags are perfectly suited for the dewatering and containment of waste in the following sectors:

  • Mining
  • Agriculture
  • Food and Beverage
  • Small-scale water and wastewater treatment
  • Golf courses
  • Residential estates

Open top

Allows for easy access to dewatered material
