Technical Talk on Tailings Dams by GHD and ATC Williams Experts (21 August, 2019)

Dredging Services uses Geotube™ geotextile dewatering containers that enable a unique solution to dewatering many types of fine-grained material, sludges and slurries
With the in-line addition of a suitable polymer flocculant, solids pumped into the Geotube™ consolidate and release water through the pores of the Geotube™ container.  Due to the surface tension exhibited by full Geotube™ containers, rain cannot permeate the geotextile weave, allowing the contained solids to become progressively drier whilst remaining fully contained.  To install Geotube™ all that’s required is a slighted graded bunded area which acts to contain the filtrate from the Geotube™ that is then returned to the respective dam or lagoon.
